Redhaven /PF-17 was at approximately at petal fall on April 15. Red Delicious is at petal fall. Apple bloom has been prolonged this year, with some varieties still in various stages of bloom. Sweet cherries are at past bloom and tart cherries are at petal fall.</p><p><strong>Peach:</strong></p><p><strong>Bacterial Spot: </strong>Copper formulations should be used starting at petal fall to suppress bacterial spot. Generally we recommend starting at 0.5 ozs metallic copper and gradually lowering the rate as the season progresses. The rate applied will depend on the formulation. Dr. Lalancette <a href="https://dev-ppa.pantheonsite.io/copper-bactericides-for-peach-bacterial-spot-management/">published a chart</a> listing common copper formulations and rates for peach and nectarine applications. Avoid combining copper with captan especially if it has been overcast for several days. Also avoid acidic spray solutions when applying copper. Dr. Lalancette has published a <a href="https://dev-ppa.pantheonsite.io/dos-and-donts-for-using-copper-to-control-peach-bacterial-spot/">handy guide</a> for copper applications in early covers. Antibiotics containing oxytetracycline may also be used and may offer slightly more residual activity during long wetting periods.</p><p><strong>Peach Scab: </strong>In addition to Rusty Spot and Bacterial Spot, Peach Scab requires protective applications starting at petal fall. Peach scab cankers begin to expand at bloom and by shuck split begin to shed spores during wetting periods. Topsin, Topsin/Captan combinations, Flint Extra, Inspire Super, and especially Quadris Top applied at petal fall are the best materials for blocks that had scab last year. Quadris Top, Flint Extra or Topsin should be used at the high rate to suppress overwintering lesions on the wood. Quadris Top contains azoxystrobin which is phytotoxic to many apple varieties. Phytotoxic residues can remain in the tank for long periods after an application is made, even if a tank cleaner is used. <strong><em>Do not use Quadris Top or Abound in the same sprayer used for apples. </em></strong>Bravo (chlorothalonil) is also a good protectant that may be applied no later than shuck split. Captan is also helpful in cover sprays after shuck split where scab was troublesome last year.</p><p><strong>Oriental Fruit Moth:</strong> A biofix point for OFM was set on 4/10 in both northern and southern counties. The first of two insecticide timings for first generation Oriental Fruit Moth control fall at 170-200 degree days base 45 after biofix. This timing generally coincides with 100% petal fall in peaches. Timings are updated below: <em>Note that timings have been pushed back from last week due to cooler than forecast weather</em>. <strong><em>Do not apply insecticides until all bloom is off. No Insecticides for OFM are needed where Mating Disruption is implemented.</em></strong></p><table><tbody><tr><td colspan="4">OFM 1<sup>st</sup> Generation Timing</td></tr><tr><td></td><td></td><td colspan="2">Insecticide Type</td></tr><tr><td>County/Region</td><td>Degree Days by 4/12 base 45</td><td>Conventional</p><p>170-200, 350-375</td><td>Diamide</p><p>100-150, 300-350</td></tr><tr><td>Gloucester – Southern</td><td>266</td><td>1<sup>st</sup> –past</p><p>2<sup>nd</sup> – 5/5-5/7</td><td>1<sup>st</sup> –past</p><p>2<sup>nd</sup> –5/2-5/5</td></tr><tr><td>Middlesex – Northern</td><td>202</td><td>1<sup>st</sup> –past</p><p>2<sup>nd</sup> –5/12-5/14</td><td> 1<sup>st</sup> – past</p><p>2<sup>nd</sup> –5/7-5/12</td></tr></tbody></table><p><strong>Green Peach Aphid:</strong> GPA colonies begin forming sometime during bloom. Examine trees for the presence of colonies from pink to shuck split. Count the number of colonies on ten trees and use a treatment threshold of 2 colonies/tree at petal fall for peach, and 1 colony/tree for nectarine. The best way to scout for aphids during bloom is with a <a href="https://www.youtube.com/watch?v=FVETlObhsIs">beating tray</a>. Blossoms may also be collected, opened, and examined for the presence of aphids using a hand lens. This is particularly important for nectarine blocks. Check 10 trees per block with the beating tray. Collect 50 blossoms per block and examine for the presence of aphids. If more than 1 colony of aphids are found in nectarines, or 2-3 colonies are found in peaches, an insecticide for aphids will be needed when all petals are off. See the <a href="https://njaes.rutgers.edu/pubs/publication.php?pid=E002">NJ Commercial Tree Fruit Production Guide for recommended materials and rates</a>. The first aphid colonies curling leaves was noted in southern counties last week.</p><p><strong>Plum Curculio; Tarnished Plant Bugs; and Other Catfacing Insects:</strong> Plum Curculio start to move into orchards at about <a href="https://plant-pest-advisory.rutgers.edu/plum-curculio-phenology-model/">88-100 degree days base 50 after January 1</a>. Applications for PC should be initiated once <strong><em>all petals are off</em></strong>, with a second application made with ovicidal materials at 379-402 DD. Currently we have accumulated about 239 DD base 50 in southern counties, and 164 DD base 50 in northern counties. Growers can monitor degree day development at their site by finding the nearest weather station and using the <a href="https://newa.cornell.edu/degree-day-calculator/">degree day development tool at NEWA</a>. Catfacing insects are starting activity but cause little damage at this time of the year. Catfacing insects will become more of an issue as temperatures warm and mowing and other ground cover activities become more common <strong><em>after bloom</em></strong>. Insecticides for catfacing insects <strong><em>are not recommended until after all petals are off</em></strong>.</p><p><strong>Scale Insects: </strong>Dormant oil applications are standard recommendations for scale control but in some years when conditions are not optimal for oil application scale control may be less than desired. Where oil was not applied or in orchards where scale is a recurring problem, an application of Centaur at petal fall or Movento between petal fall and shuck split should “clean up” problem blocks. Centaur is recommended at 34.5 ozs./ac and Movento should be applied at 6-9 ozs./ac. A penetrant must be included to Movento as per the product label. Movento will also control green peach aphid when used at this timing.</p><p><strong>Lesser and Greater Peach Tree Borers:</strong> Growers using mating disruption for borer control can begin placing dispensers around the end of April and should have them in place by mid-May.</p><p><strong>Apples and Pears:</strong></p><p><strong>Diseases:</strong> Fire Blight, Apple Scab, Rust diseases, and Powdery Mildew are the main targets at this stage. The <a href="https://newa.cornell.edu/index.php?page=apple-diseases">NEWA apple scab model</a> is estimating about 98% ascospore maturity as of 4/22 in southern NJ with 92% of cumulative ascospores discharged. The model estimates about 98% ascopsore maturity for Northern Counties with 90% ascospores released. Primary apple scab spores are released during any substantial <a href="https://web.uri.edu/ipm/2013/05/mills-table-apple-scab-infection-periods/">infection period</a>. Between tight cluster and first cover include products effective for powdery mildew and cedar apple rust. To manage Fire Blight in both apples and pears, consider using Kasumin at bloom. Kasumin is an antibiotic like Streptomycin and Oxytetratracycline. It contains Kasugamycin which is a different chemistry. Kasumin is only labeled for bloom and petal fall applications while strep and oxytet are labeled for post bloom use (<strong><em>Note that Fireline 45 is only labeled for 1 post bloom application on apple.)</em></strong>. Using 3 different chemistries in rotation allows for resistance management while extending the protection into the post bloom period when late blossoms typically appear which ever material you use, the addition of Actigard, Lifegard, or other plant defense elicitors may improve control.</p><p><strong>Rust Diseases: </strong>The two most common rust diseases that affect pome fruit are Quince Rust and Cedar Apple Rust. In some years these diseases can be troublesome in commercial orchards. Most disease control programs for scab will also control rust. In organically managed blocks in the east options are limited for approved materials that are effective for rust. Potassium Bicarbonate products have shown good efficacy for rust diseases in trials performed in Virginia. Organic growers should seek out and plant rust resistant cultivars. Cultural controls are not practicable due to the widespread presence of alternate host Junipers both wild and cultivated. Rust disease development on junipers should now be producing large spore releases during wetting periods. See this <a href="https://blogs.cornell.edu/plantpathhvl/apple-diseases/rust-diseases/">link for pictures of rust </a>on pome fruit and juniper.</p><p><strong>Codling Moth: </strong>A Codling Moth Biofix was set in Southern counties on 4/22. See the <a href="https://njaes.rutgers.edu/pubs/publication.php?pid=E002">NJ Commercial Tree Fruit Production Guide for recommended materials and rates</a>. Where Mating Disruption has been employed, supplemental Madex applications should be made at the timings listed below.</p><table width="74%"><tbody><tr><td width="11%"></td><td colspan="8" width="85%">Codling Moth Degree Day Timing</td></tr><tr><td width="11%"></td><td width="10%"></td><td colspan="7" width="74%">Application and Insecticide Type</td></tr><tr><td width="11%">County Area</td><td width="10%">Biofix</td><td colspan="2" width="17%">Rimon:</p><p>75-100DD + 14-17 days later</p><p> </td><td colspan="2" width="18%">Intrepid</p><p>150 + 450 DD</p><p>Diamides – Altacor, Voliam mixes: (150-200 DD)</td><td width="19%">Madex</p><p>250 DD + every 7-9 days during brood hatch (later if first spray is an IGR)</td><td colspan="2" width="19%">Standard Insecticides – Delegate, Avaunt, OP’s, carbamates, pyrethroids</p><p>250 DD + 550 DD</p><p> </td></tr><tr><td width="11%">DD</td><td width="10%"></td><td width="8%">75</td><td width="9%">100</td><td width="8%">150</td><td width="9%">450</td><td width="19%">250</td><td width="9%">250</td><td width="9%">550</td></tr><tr><td width="11%">Southern</td><td width="10%">April 22</td><td width="8%">4/30</td><td width="9%">5/2</td><td width="8%">5/8</td><td width="9%">Too far off</td><td width="19%">Too far off</td><td width="9%">Too far off</td><td width="9%">Too far off</td></tr><tr><td width="11%">Northern</td><td width="10%">May 1</td><td width="8%">5/7</td><td width="9%">5/9</td><td width="8%">5/13</td><td width="9%">Too far off</td><td>Too far off</td><td>Too far off</td><td>Too far off</td></tr></tbody></table><p> </p><p><strong>Scale Insects/Apple Aphids: </strong>Dormant oil applications are standard recommendations for scale control but in some years when conditions are not optimal for oil application scale control may be less than desired. Where oil was not applied or in orchards where scale is a recurring problem, an application of Centaur at petal fall or Movento at petal fall should “clean up” problem blocks. Centaur is recommended at 34.5 ozs./ac and Movento should be applied at 6-9 ozs./ac. A penetrant must be included with Movento as per the product label. Movento should also control apple aphids, including Wooly Aphid, when used at this timing. In pears Movento may also control aphids and suppress 1st generation pear psylla when applied at petal fall.</p><p><strong>Rosy Apple Aphid: </strong> If a pre-bloom application was not made, monitor for colonies during bloom and use a treatment threshold of 1 colony/tree at petal fall. Low levels of rosy aphid colonies were observed in southern county orchards this week.</p><p><strong>Ambrosia Beetle : </strong>Across all northern counties, we are seeing this pest attacking our wood dowel traps. We were catching fewer beetles on our clear sticky traps, however the these past hot days have a marked an increase in captures. This likely means the first-generation flight slowed from cool weather as they are moving into orchards in search of stressed trees to attack. Once these beetles bore into the trunk, they will form a gallery in the heartwood of the tree to lay their eggs and farm the ambrosia fungus to feed themselves and their larvae. Once the female lays her eggs, it will take about 30 days for them to become adults and emerge from their host tree to begin the second flight. If you have had a history of this pest in your orchard, you should begin scouting for damage and remove any trees that have been attacked. It may be beneficial to leave attacked trees in the orchard for a few weeks before removal so they can act as trap trees to reduce populations.</p><p><strong>Pear Psylla: </strong> In lieu of oil or insecticides, Surround may also be applied starting at swollen bud and continued through petal fall. If using Surround through the bloom period stop at petal fall and switch to applications of 1% summer oil @ 1gal/100 in no less than 150 gals/ac. these should be made at no more than 2 week intervals. At petal fall insecticide options for Psylla control include Actara, Assail, Belay, Movento, Sivanto Prime, and Agri-mek. See the <a href="https://njaes.rutgers.edu/pubs/publication.php?pid=E002">NJ Commercial Tree Fruit Production Guide for recommended materials and rates</a>.</p><p><strong>Pear Diseases:</strong> Include effective materials such as Ziram or EBDC formulations for Pear Scab and Rust diseases beginning at the cluster bud stage. At white bud use products effective for pear scab, rusts, <strong><em>and</em></strong> fabrea leaf spot. For both apples and pears, consider using Kasumin at bloom. Kasumin is an antibiotic like Streptomycin and Oxytetratracycline. It contains Kasugamycin which is a different chemistry. Kasumin is only labeled for bloom and petal fall applications while strep and oxytetracycline are labeled for post bloom use. Using 3 different chemistries in rotation allows for resistance management while extending the protection into the post bloom period when late blossoms typically appear. Whichever material you use, the addition of Actigard, Lifegard, or other plant defense elicitors may improve control.</p><p><strong>Grapes Grapes: </strong>The most important diseases to manage at this time are Phomopsis and Powdery Mildew. At 3″ growth start managing for Black Rot. More information about early season disease control can be found in this <a href="https://ext.grapepathology.org/reminders-for-early-season-grape-disease-management">blogpost from Virginia Tech</a>. Insect pests to monitor are <a href="https://www.canr.msu.edu/ipm/diseases/grape_flea_beetle">Grape Flea Beetle</a>, and <a href="https://grapes.extension.org/climbing-cutworms/">Climbing Cutworms</a>. Controls for these insects are rarely needed. If control is determined to be necessary, use one of the materials recommended in the <a href="https://njaes.rutgers.edu/pubs/publication.php?pid=E283">New Jersey Commercial Grape Production Guide</a>. Spotted Lantern Fly nymphs (Fig. 1) usually begin to emerge around this time in southern counties. We have not observed any yet. There is no need to control SLF at this time.</p><div id="attachment_35305" style="width: 235px" class="wp-caption aligncenter"><a

Affected crops include chives, scallions, garlic, onions and leeks. Look for neat rows of white spots descending from the upper tips of allium leaves <strong>(see photo at left)</strong>. Initial injury often occurs on the tallest leaves. Under warmer, less breezy conditions, adults may be seen near the tips of leaves <strong>(see photo of adult at lower right)</strong>. Perennial chive beds are often the first, and most heavily infested alliums of the spring season, so this makes chives an ideal crop to confirm ALM adult activity.</p><p>Floating row covers, kept on until this flight ends will help minimize access to plants.

The test sample required from lactating dairy cattle is milk/udder secretions from each quarter per individual cow (ensure each quarter is sampled, as there have been reports of only one quarter having the virus), which is then combined into one sample tube (a total volume of 3-10 ml of milk per animal should be submitted). The samples can be submitted to the NJDA Animal Health Diagnostic Laboratory (AHDL), a USDA-approved National Animal Health Laboratory Network (NAHLN) laboratory. Samples submitted to the NJDA AHDL will be tested by real-time polymerase chain reaction (PCR) assay for influenza A, <span style="text-decoration: underline;">which will be completed at no cost to the producers/veterinarians.</span> Influenza A testing for interstate dairy cattle movement is an additional requirement to the preexisting livestock importation regulations in New Jersey, N.J.A.C. 2:3 Livestock and Poultry Importation. Persons moving dairy cattle are reminded that these requirements are in addition to the official identification, certificate of veterinary inspection (CVI), and testing requirements conventionally required for cattle movement. Please consult the receiving state to confirm all other interstate movement requirements prior to affecting an animal’s movement.</p><p><em>Listed below are particularly important aspects of the Federal Order and USDA guidance.</em></p><p><strong>Mandatory Testing for Interstate Movement of Dairy Cattle:</strong></p><ul><li>Prior to interstate movement, non-clinical lactating dairy cows are required to receive a negative test for Influenza A virus at an approved National Animal Health Laboratory Network (NAHLN) laboratory in addition to meeting the importing state’s testing requirements and a certificate of veterinary inspection (CVI).</li><li>Non-clinical lactating dairy cows moving interstate direct to slaughter do not require influenza A testing but require a certificate of veterinary inspection (CVI).</li><li>Non-clinical lactating dairy cows moving interstate through auction markets in New Jersey to out-of-state slaughter do not require influenza A testing but require a certificate of veterinary inspection (CVI).</li><li>Non-clinical lactating dairy cows moving interstate to auction market in another state require influenza A testing and a certificate of veterinary inspection.</li><li>Nonlactating dairy cattle, including bull calves, dry cows, and heifers; and beef cattle are exempt from Influenza A testing for interstate movement.</li><li>Movement tests are valid for seven (7) days from the date of sample collection.</li><li>For imported cattle attending a New Jersey Fair/Show, Influenza A testing is required for lactating dairy cattle in addition to meeting requirements in the 2024 fair and show letter.</li><li>Owners of herds in which dairy cattle test positive for interstate movement will be required to provide epidemiological information, including animal movement tracing.</li><li>Sick cattle are not eligible for movement. Dairy cattle herds that have tested positive for influenza A must wait 30 days and retest negative to be eligible for movement.</li></ul><p><strong>Mandatory Reporting: </strong>Laboratories and state veterinarians must report positive Influenza A detection diagnostic results in livestock to USDA APHIS.</p>]]></content:encoded> <post-id xmlns="com-wordpress:feed-additions:1">35284</post-id> </item> <item> <title>26th Biennial International Pepper Conference Returns to Northeast, Sept 9-11, 2024</title> <link>https://plant-pest-advisory.rutgers.edu/26th-biennial-international-pepper-conference-returns-to-northeast-sept-9-11-2024/</link> <dc:creator><![CDATA[Rick VanVranken]]></dc:creator> <pubDate>Thu, 25 Apr 2024 20:11:31 +0000</pubDate> <category><![CDATA[Vegetable Crops]]></category> <category><![CDATA[bell pepper]]></category> <category><![CDATA[Conferences]]></category> <category><![CDATA[research]]></category> <category><![CDATA[specialty peppers]]></category> <guid isPermaLink="false">https://plant-pest-advisory.rutgers.edu/?p=35276</guid> <description><![CDATA[Cornell announces they will be hosting the International Pepper Conference 2024 “Fall in New York’s Finger Lakes Region is the perfect time to visit local waterfalls, revel in colorful foliage, and explore our ripening pepper selection!

We are excited to be hosting the 26th Annual International Pepper Conference in Ithaca, NY and are looking forward to showcasing peppers in our region. I’m especially excited about this year’s field day. On Tuesday, September 10, we’ll travel around Central New York, touring Cornell University research plots, visiting Norwich Meadows Farm, and taking in one of Ithaca’s “gorges” waterfalls. I’m looking forward to welcoming all of you to Ithaca and sharing the latest scientific information and pepper breeding projects.<br />—- Michael Mazourek, Plant Breeding & Genetics, Cornell University</p><p>The <a href="https://extension.arizona.edu/ipc/sites/extension.arizona.edu.ipc/files/2022-02/Origin%20and%20History%20of%20the%20National%20Pepper%20Conference.pdf">International Pepper Conference</a> has been held every couple of years since 1973 and is not limited to researchers working on peppers.

In southern counties all peach orchards are petal fall to shuck split. Redhaven /PF-17 was at approximately full bloom on April 5. Plums are at shuck off. Pears are at petal fall. Red Delicious is just past full bloom. Sweet cherries are at about late bloom depending on variety.</p><p><strong>Peach:</strong></p><p><strong>Bacterial Spot: </strong>Copper formulations should be used starting at petal fall to suppress bacterial spot. Generally we recommend starting at 0.5 ozs metallic copper and gradually lowering the rate as the season progresses. The rate applied will depend on the formulation. Dr. Lalancette <a href="https://dev-ppa.pantheonsite.io/copper-bactericides-for-peach-bacterial-spot-management/">published a chart</a> listing common copper formulations and rates for peach and nectarine applications. Avoid combining copper with captan especially if it has been overcast for several days. Also avoid acidic spray solutions when applying copper. Dr. Lalancette has published a <a href="https://dev-ppa.pantheonsite.io/dos-and-donts-for-using-copper-to-control-peach-bacterial-spot/">handy guide</a> for copper applications in early covers. Antibiotics containing oxytetracycline may also be used and may offer slightly more residual activity during long wetting periods.</p><p><strong>Peach Scab: </strong>In addition to Rusty Spot and Bacterial Spot, Peach Scab requires protective applications starting at petal fall. Peach scab cankers begin to expand at bloom and by shuck split begin to shed spores during wetting periods. Topsin, Topsin/Captan combinations, Flint Extra, Inspire Super, and especially Quadris Top applied at petal fall are the best materials for blocks that had scab last year. Quadris Top, Flint Extra or Topsin should be used at the high rate to suppress overwintering lesions on the wood. Quadris Top contains azoxystrobin which is phytotoxic to many apple varieties. Phytotoxic residues can remain in the tank for long periods after an application is made, even if a tank cleaner is used. <strong><em>Do not use Quadris Top or Abound in the same sprayer used for apples. </em></strong>Bravo (chlorothalonil) is also a good protectant that may be applied no later than shuck split. Captan is also helpful in cover sprays after shuck split where scab was troublesome last year.</p><p><strong>Oriental Fruit Moth:</strong> A biofix point for OFM was set on 4/10 in both northern and southern counties. The first of two insecticide timings for first generation Oriental Fruit Moth control fall at 170-200 degree days base 45 after biofix. This timing generally coincides with 100% petal fall in peaches. Timings are updated below: <em>Note that timings have been pushed back from last week due to cooler than forecast weather</em>. <strong><em>Do not apply insecticides until all bloom is off. No Insecticides for OFM are needed where Mating Disruption is implemented.</em></strong></p><table><tbody><tr><td colspan="4">OFM 1<sup>st</sup> Generation Timing</td></tr><tr><td></td><td></td><td colspan="2">Insecticide Type</td></tr><tr><td>County/Region</td><td>Degree Days by 4/12 base 45</td><td>Conventional</p><p>170-200, 350-375</td><td>Diamide</p><p>100-150, 300-350</td></tr><tr><td>Gloucester – Southern</td><td>20</td><td>1<sup>st</sup> –4/26-4/29</p><p>2<sup>nd</sup> –</td><td>1<sup>st</sup> –4/16-4/23</p><p>2<sup>nd</sup> –</td></tr><tr><td>Middlesex – Northern</td><td>12</td><td>1<sup>st</sup> –5/2-5/8</p><p>2<sup>nd</sup> –</td><td> 1<sup>st</sup> – 4/22-5/2</p><p>2<sup>nd</sup> –</td></tr></tbody></table><p><strong>Green Peach Aphid:</strong> GPA colonies begin forming sometime during bloom. Examine trees for the presence of colonies from pink to shuck split. Count the number of colonies on ten trees and use a treatment threshold of 2 colonies/tree at petal fall for peach, and 1 colony/tree for nectarine. The best way to scout for aphids during bloom is with a <a href="https://www.youtube.com/watch?v=FVETlObhsIs">beating tray</a>. Blossoms may also be collected, opened, and examined for the presence of aphids using a hand lens. This is particularly important for nectarine blocks. Check 10 trees per block with the beating tray. Collect 50 blossoms per block and examine for the presence of aphids. If more than 1 colony of aphids are found in nectarines, or 2-3 colonies are found in peaches, an insecticide for aphids will be needed when all petals are off. See the <a href="https://njaes.rutgers.edu/pubs/publication.php?pid=E002">NJ Commercial Tree Fruit Production Guide for recommended materials and rates</a>. The first aphid activity was noted in southern counties last week.</p><p><strong>Plum Curculio; Tarnished Plant Bugs; and Other Catfacing Insects:</strong> Plum Curculio start to move into orchards at about <a href="https://plant-pest-advisory.rutgers.edu/plum-curculio-phenology-model/">88-100 degree days base 50 after January 1</a>. Applications for PC should be initiated once <strong><em>all petals are off</em></strong>, with a second application made with ovicidal materials at 379-402 DD. Currently we have accumulated about 168 DD base 50 in southern counties, and 109 DD base 50 in northern counties. Growers can monitor degree day development at their site by finding the nearest weather station and using the <a href="https://newa.cornell.edu/degree-day-calculator/">degree day development tool at NEWA</a>. Catfacing insects are starting activity but cause little damage at this time of the year. Catfacing insects will become more of an issue as temperatures warm and mowing and other ground cover activities become more common <strong><em>after bloom</em></strong>. Insecticides for catfacing insects <strong><em>are not recommended until after all petals are off</em></strong>.</p><p><strong>Scale Insects: </strong>Dormant oil applications are standard recommendations for scale control but in some years when conditions are not optimal for oil application scale control may be less than desired. Where oil was not applied or in orchards where scale is a recurring problem, an application of Centaur at petal fall or Movento between petal fall and shuck split should “clean up” problem blocks. Centaur is recommended at 34.5 ozs./ac and Movento should be applied at 6-9 ozs./ac. A penetrant must be included to Movento as per the product label. Movento will also control green peach aphid when used at this timing.</p><p><strong>Lesser and Greater Peach Tree Borers:</strong> Growers using mating disruption for borer control can begin placing dispensers around the end of April and should have them in place by mid-May.</p><p><strong>Apples and Pears:</strong></p><p><strong>Diseases:</strong> Fire Blight, Apple Scab, Rust diseases, and Powdery Mildew are the main targets at this stage. The <a href="https://newa.cornell.edu/index.php?page=apple-diseases">NEWA apple scab model</a> is estimating about 88% ascospore maturity as of 4/22 in southern NJ with 83% of cumulative ascospores discharged. The model estimates about 69% ascopsore maturity for Northern Counties with 43% ascospores released. Primary apple scab spores are released during any substantial <a href="https://web.uri.edu/ipm/2013/05/mills-table-apple-scab-infection-periods/">infection period</a>. Between tight cluster and first cover include products effective for powdery mildew and cedar apple rust. To manage Fire Blight in both apples and pears, consider using Kasumin at bloom. Kasumin is an antibiotic like Streptomycin and Oxytetratracycline. It contains Kasugamycin which is a different chemistry. Kasumin is only labeled for bloom and petal fall applications while strep and oxytet are labeled for post bloom use (<strong><em>Note that Fireline 45 is only labeled for 1 post bloom application on apple.)</em></strong>. Using 3 different chemistries in rotation allows for resistance management while extending the protection into the post bloom period when late blossoms typically appear which ever material you use, the addition of Actigard, Lifegard, or other plant defense elicitors may improve control.</p><p><strong>Rust Diseases: </strong>The two most common rust diseases that affect pome fruit are Quince Rust and Cedar Apple Rust. In some years these diseases can be troublesome in commercial orchards. Most disease control programs for scab will also control rust. In organically managed blocks in the east options are limited for approved materials that are effective for rust. Potassium Bicarbonate products have shown good efficacy for rust diseases in trials performed in Virginia. Organic growers should seek out and plant rust resistant cultivars. Cultural controls are not practicable due to the widespread presence of alternate host Junipers both wild and cultivated. Rust disease development on junipers should now be producing large spore releases during wetting periods. See this <a href="https://blogs.cornell.edu/plantpathhvl/apple-diseases/rust-diseases/">link for pictures of rust </a>on pome fruit and juniper.</p><p><strong>Codling Moth: </strong>A Codling Moth Biofix was set in Southern counties on 4/22. See the <a href="https://njaes.rutgers.edu/pubs/publication.php?pid=E002">NJ Commercial Tree Fruit Production Guide for recommended materials and rates</a>. Where Mating Disruption has been employed, supplemental Madex applications should be made at the timings listed below.</p><table width="74%"><tbody><tr><td width="11%"></td><td colspan="8" width="85%">Codling Moth Degree Day Timing</td></tr><tr><td width="11%"></td><td width="10%"></td><td colspan="7" width="74%">Application and Insecticide Type</td></tr><tr><td width="11%">County Area</td><td width="10%">Biofix</td><td colspan="2" width="17%">Rimon:</p><p>75-100DD + 14-17 days later</p><p> </td><td colspan="2" width="18%">Intrepid</p><p>150 + 450 DD</p><p>Diamides – Altacor, Voliam mixes: (150-200 DD)</td><td width="19%">Madex</p><p>250 DD + every 7-9 days during brood hatch (later if first spray is an IGR)</td><td colspan="2" width="19%">Standard Insecticides – Delegate, Avaunt, OP’s, carbamates, pyrethroids</p><p>250 DD + 550 DD</p><p> </td></tr><tr><td width="11%">DD</td><td width="10%"></td><td width="8%">75</td><td width="9%">100</td><td width="8%">150</td><td width="9%">450</td><td width="19%">250</td><td width="9%">250</td><td width="9%">550</td></tr><tr><td width="11%">Southern</td><td width="10%">April 22</td><td width="8%">4/30</td><td width="9%">5/2</td><td width="8%">5/5</td><td width="9%">Too far off</td><td width="19%">5/11</td><td width="9%">5/11</td><td width="9%">Too far off</td></tr><tr><td width="11%">Northern</td><td width="10%"></td><td width="8%"></td><td width="9%"></td><td width="8%"></td><td width="9%"></td><td></td><td></td><td></td></tr></tbody></table><p><strong>Scale Insects: </strong>Dormant oil applications are standard recommendations for scale control but in some years when conditions are not optimal for oil application scale control may be less than desired.

Centaur is recommended at 34.5 ozs./ac and Movento should be applied at 6-9 ozs./ac. A penetrant must be included to Movento as per the product label. Movento will also control apple aphids, including Wooly Aphid, when used at this timing. In pears Movento may also control aphids and 1st generation pear psylla when applied at petal fall.</p><p><strong>Rosy Apple Aphid: </strong> If a pre-bloom application was not made, monitor for colonies during bloom and use a treatment threshold of 1 colony/tree at petal fall.</p><p><strong>Ambrosia Beetle: </strong>This pest has traditionally been an economically damaging pest of ornamental crops. In more recent years we have found it opportunistically attacking our tree fruit orchards. Ambrosia Beetles are attracted to young, stressed trees with trunks no greater than 4 inches in diameter, however it will attack larger trees in some years. Over the past few years, some New Jersey farms have experienced significant tree loss to this pest. In northern counties we are been experimenting with Ambrosia Beetle monitoring tools. Each farm in the program has had one clear sticky trap with a commercial ethanol lure and three wood dowel traps filled with ethyl alcohol placed along the wood line closest to their tree fruit orchards. The clear sticky trap is being used to monitor flights of this pest while the wood dowel traps are being used to time management decisions. We had our first Ambrosia Beetle trap catch on 4/8, since then this pest has been caught on the clear sticky traps at every location they were placed at. We had our first damage to the wood dowel traps on 4/18 so we can expect to see these beetles becoming an issue in orchards where they have historically attacked relatively soon. Indeed we have seen tunneling in southern county orchards this past week.</p><p><strong>Pear Psylla: </strong> Dormant oil applications should have already been started to deter psylla egg laying. At the green cluster stage a pyrethroid or Esteem is generally included with oil. Pyrethroids may knock down some of the adults migrating into the orchard, while Esteem may sterilize them. In lieu of oil or insecticides, Surround may also be applied starting at swollen bud and continued through petal fall. If using Surround through the bloom period stop at petal fall and switch to applications of 1% summer oil @ 1gal/100 in no less than 150 gals/ac. these should be made at no more than 2 week intervals. At petal fall insecticide options for Psylla control include Actara, Assail, Belay, Movento, Sivanto Prime, and Agri-mek. See the <a href="https://njaes.rutgers.edu/pubs/publication.php?pid=E002">NJ Commercial Tree Fruit Production Guide for recommended materials and rates</a>.</p><p><strong>Pear Diseases:</strong> Include effective materials such as Ziram or EBDC formulations for Pear Scab and Rust diseases beginning at the cluster bud stage. At white bud use products effective for pear scab, rusts, <strong><em>and</em></strong> fabrea leaf spot. For both apples and pears, consider using Kasumin at bloom. Kasumin is an antibiotic like Streptomycin and Oxytetratracycline. It contains Kasugamycin which is a different chemistry. Kasumin is only labeled for bloom and petal fall applications while strep and oxytetracycline are labeled for post bloom use. Using 3 different chemistries in rotation allows for resistance management while extending the protection into the post bloom period when late blossoms typically appear. Whichever material you use, the addition of Actigard, Lifegard, or other plant defense elicitors may improve control.</p><p><strong>Grapes: </strong>Grapes are at budbreak to the 3″ stage of development. The most important disease to manage at this time is Phomopsis. Insect pests to monitor are <a href="https://www.canr.msu.edu/ipm/diseases/grape_flea_beetle">Grape Flea Beetle</a>, and <a href="https://grapes.extension.org/climbing-cutworms/">Climbing Cutworms</a>. Controls for these insects are rarely needed. If control is determined to be necessary, use one of the materials recommended in the <a href="https://njaes.rutgers.edu/pubs/publication.php?pid=E283">New Jersey Commercial Grape Production Guide</a>. It’s also not too late to scout for and <a href="https://extension.psu.edu/how-to-remove-spotted-lanternfly-eggs">destroy SLF egg masses</a> on posts and trunks.</p><p><strong>Phenology Table: Based

The workshop focuses on insects recovered from a 1683 grave that was excavated at Historic St. Mary’s City, Maryland. Historic St. Mary’s City was the first permanent British settlement in Maryland, located on a small rural coastal peninsula east of modern-day Washington, DC. Today, the site is still a farming operation that mainly grows field crops.</p><p style="font-weight: 400;">Registration is free and can be found on the workshop’s homepage here: <a href="https://go.rutgers.edu/mll66dzo" target="_blank" rel="noopener">https://go.rutgers.edu/mll66dzo</a></p><p style="font-weight: 400;"><em>Workshop Details</em></p><p style="font-weight: 400;">Dr. George Hamilton’s Integrated Pest Management (IPM) Laboratory at the Rutgers Department of Entomology is studying historical insects from the <a href="https://www.hsmcdigshistory.org/research/archaeology-and-architecture/projects/the-lead-coffins-project/" target="_blank" rel="noopener">Philip Calvert grave at Historic St. Mary’s City</a> and the insect biodiversity of the modern site. One goal of this project is understanding if the same beneficial rove beetle species have survived in the area as land use around the site has changed over time.</p><p style="font-weight: 400;">The workshop’s purpose is to get feedback from the agricultural community on the project after going through some of the activities used to study the historical insects and gather modern site data. First, the workshop will start at 10:30am with learning more about the project and the archaeology of Historic St. Mary’s City through two 10-minute talks. Then, three break-out groups will rotate through guided insect collecting in the field, recognizing historical insect fragments under laboratory microscopes, and seeing how maggots move after leaving a death scene by making insect art.</p><p style="font-weight: 400;">Everyone who attends will receive a folding pocket scope on behalf of NOFA-NJ for viewing insects they collect and are invited to take home their maggot insect art.</p><p style="font-weight: 400;">Lunch will be provided around noon after breakout groups complete each hands-on activity. Coffee will be served, and a short talk will give an overview of the investigation’s current findings. Finally, before the workshop ends at 2:00pm project members will lead a brief group discussion about how studying insects in archaeology can be used for sustainable agriculture.</p><p style="font-weight: 400;">For example, identifying native rove beetles that have existed at a location for 100s of years then developing an IPM farmscaping or habitat manipulation program targeted to increase populations of those beneficial insects.</p><p style="font-weight: 400;"><em>Additional Background Information</em></p><p style="font-weight: 400;">The study of insects and other arthropods in archaeology sites <a href="https://orb.binghamton.edu/neha/vol33/iss1/8">is referred to as archaeoentomology</a>. In Europe archaeoentomology has been used to show <a href="https://linkinghub.elsevier.com/retrieve/pii/S027737911630542X">fleas and grain weevils moved with migrating humans over 5,000 years ago</a>. Changes in archaeoentomology beetle species found at early European farms <a href="https://royalsocietypublishing.org/doi/10.1098/rspb.2021.2734">represent changing land use once agriculture became established</a>. However, even though insects are all around us, archaeoentomology is usually <a href="https://doi.org/10.1080/00438243.2019.1610492">overlooked when researchers try to design new sustainable agriculture practices</a>.</p><p style="font-weight: 400;">Very little archaeoentomology research has been conducted in the United States. This provides an opportunity for developing American archaeoentomology as a field focused on <a href="https://www.sciencedirect.com/science/article/pii/S2352409X20303904">understanding changes in the food system over time related to crop pests</a> and beneficial insects.</p><p style="font-weight: 400;">Parking information and the link to the registration form can be found on the workshop’s homepage here: <a href="https://go.rutgers.edu/mll66dzo" target="_blank" rel="noopener">https://go.rutgers.edu/mll66dzo</a></p><p style="font-weight: 400;">In addition to farmers, growers, ranchers, farm workers, beekeepers and other members of the agriculture industry, this workshop is free and open to college students interested in agriculture, Master Gardeners, and other interested community members.</p><p style="font-weight: 400;">Please contact Mike with any questions at <a href="mailto:mmonzon@njaes.rutgers.edu">mmonzon@njaes.rutgers.edu</a></p><p style="font-weight: 400;"><em>This event is a collaboration between NOFA-NJ, George Hamilton’s Integrated Pest Management (IPM) Laboratory at the Rutgers University Department of Entomology, and the Fahrenfeld Research Group at the Rutgers University Department of Civil and Environmental Engineering and is supported by the National Institute of Food and Agriculture, U.S. Department of Agriculture, through the Northeast Sustainable Agriculture Research and Education program under subaward number GNE22-292.</em></p>]]></content:encoded> <post-id xmlns="com-wordpress:feed-additions:1">35242</post-id> </item> <item> <title>2024 National Agritourism Survey</title> <link>https://plant-pest-advisory.rutgers.edu/2024-national-agritourism-survey-2/</link> <dc:creator><![CDATA[Claudia Gil Arroyo]]></dc:creator> <pubDate>Mon, 15 Apr 2024 16:09:07 +0000</pubDate> <category><![CDATA[Christmas Trees]]></category> <category><![CDATA[Fruit]]></category> <category><![CDATA[Landscape, Nursery, & Turf]]></category> <category><![CDATA[Vegetable Crops]]></category> <category><![CDATA[agritourism]]></category> <category><![CDATA[national survey]]></category> <guid isPermaLink="false">https://plant-pest-advisory.rutgers.edu/?p=35238</guid> <description><![CDATA[The 2024 National Agritourism Survey is now collecting responses.

In southern counties all peach orchards are late bloom to petal fall. Redhaven and PF-17 were at approximately full bloom on April 6. Plums are at shuck split. Pears are full bloom for Asian varieties and first bloom for Europeans. Apples and cherries are coming into bloom.</p><p><strong>Peach:</strong></p><p><strong>Brown Rot:</strong> Blossom infections from the brown rot fungus can occur whenever pistils are exposed and a favorable climate exists. Infections can occur during any wetting period when temperatures are between 41 and 86 °F. However, optimum conditions for infection occur with wetting and temperatures in the mid 70’s. During long wetting periods (several days or more) blossoms can be infected regardless of temperature. Generally infections that occur when conditions are sub optimal are less severe. Blossoms and fruitlets will remain susceptible until the pistil desiccates (sometime between petal fall and shuck split). Initiate coverage for blossom blight starting at pink for short petal varieties and 5-10% bloom for showy flowers. See the <a href="https://njaes.rutgers.edu/pubs/publication.php?pid=E002">NJ Commercial Tree Fruit Production Guide for recommended materials and rates</a>.</p><p><strong>Bacterial Spot: </strong>Copper formulations should be used starting at petal fall to suppress bacterial spot. Generally we recommend starting at 0.5 ozs metallic copper and gradually lowering the rate as the season progresses. The rate applied will depend on the formulation. Dr. Lalancette <a href="https://dev-ppa.pantheonsite.io/copper-bactericides-for-peach-bacterial-spot-management/">published a chart</a> listing common copper formulations and rates for peach and nectarine applications. Avoid combining copper with captan especially if it has been overcast for several days. Also avoid acidic spray solutions when applying copper. Dr. Lalancette has published a <a href="https://dev-ppa.pantheonsite.io/dos-and-donts-for-using-copper-to-control-peach-bacterial-spot/">handy guide</a> for copper applications in early covers. Antibiotics such as Mycoshield or Fireline may also be used and may offer slightly more residual activity during long wetting periods.</p><p><strong>Peach Scab: </strong>In addition to Rusty Spot and Bacterial Spot, Peach Scab requires protective applications starting at petal fall. Peach scab cankers (Fig. 1) begin to expand at bloom and by shuck split begin to shed spores during wetting periods. Topsin, Topsin/Captan combinations, Flint Extra, Inspire Super, and especially Quadris Top applied at petal fall are the best materials for blocks that had scab last year. Quadris Top, Flint Extra or Topsin should be used at the high rate to suppress overwintering lesions on the wood. Quadris Top contains azoxystrobin which is phytotoxic to many apple varieties. Phytotoxic residues can remain in the tank for long periods after an application is made, even if a tank cleaner is used. <strong><em>Do not use Quadris Top or Abound in the same sprayer used for apples. </em></strong>Bravo (chlorothalonil) is also a good protectant that may be applied no later than shuck split. Captan is also helpful in cover sprays after shuck split where scab was troublesome last year.</p><div id="attachment_22259" style="width: 310px" class="wp-caption aligncenter"><a href="https://plant-pest-advisory.rutgers.edu/wp-content/uploads/2020/04/Peach-Scab-lesions-twig040109-020-scaled.jpg"><img loading="lazy" decoding="async" aria-describedby="caption-attachment-22259" class="wp-image-22259 size-medium" src="https://plant-pest-advisory.rutgers.edu/wp-content/uploads/2020/04/Peach-Scab-lesions-twig040109-020-300x225.jpg" alt="" width="300" height="225" srcset="https://plant-pest-advisory.rutgers.edu/wp-content/uploads/2020/04/Peach-Scab-lesions-twig040109-020-300x225.jpg 300w, https://plant-pest-advisory.rutgers.edu/wp-content/uploads/2020/04/Peach-Scab-lesions-twig040109-020-1024x768.jpg 1024w, https://plant-pest-advisory.rutgers.edu/wp-content/uploads/2020/04/Peach-Scab-lesions-twig040109-020-768x576.jpg 768w, https://plant-pest-advisory.rutgers.edu/wp-content/uploads/2020/04/Peach-Scab-lesions-twig040109-020-1536x1152.jpg 1536w, https://plant-pest-advisory.rutgers.edu/wp-content/uploads/2020/04/Peach-Scab-lesions-twig040109-020-2048x1536.jpg 2048w" sizes="(max-width: 300px) 100vw, 300px" /></a><p id="caption-attachment-22259" class="wp-caption-text">Fig. 1 Peach Scab lesions on peach twig.</p></div><p> </p><p><strong>Oriental Fruit Moth:</strong> A biofix point for OFM was set on 4/11 in both northern and southern counties. It is not too late to place dispensers for OFM mating disruption, however if they aren’t in place soon the first generation should be controlled with insecticides. The first insecticides for first generation Oriental Fruit Moth control should be applied at 170-200 degree days base 45 after biofix. This timing generally coincides with 100% petal fall in peaches. <strong><em>Do not apply insecticides until all bloom is off regardless of degree day timing. No Insecticides for OFM should be needed needed where Mating Disruption is implemented.</em></strong></p><table><tbody><tr><td colspan="4">OFM 1<sup>st</sup> Generation Timing</td></tr><tr><td></td><td></td><td colspan="2">Insecticide Type</td></tr><tr><td>County/Region</td><td>Degree Days by 4/12 base 45</td><td>Conventional</p><p>170-200, 350-375</td><td>Diamide</p><p>100-150, 300-350</td></tr><tr><td>Gloucester – Southern</td><td>20</td><td>1<sup>st</sup> –4/20-4/22</p><p>2<sup>nd</sup> –</td><td>1<sup>st</sup> –4/16-4/18</p><p>2<sup>nd</sup> –</td></tr><tr><td>Middlesex – Northern</td><td>12</td><td>1<sup>st</sup> –4/20-4/22</p><p>2<sup>nd</sup> –</td><td> 1<sup>st</sup> – 4/18-4/20</p><p>2<sup>nd</sup> –</td></tr></tbody></table><p><strong>Green Peach Aphid:</strong> GPA colonies begin forming sometime during bloom. Examine trees for the presence of colonies from pink to shuck split. Count the number of colonies on ten trees and use a treatment threshold of 2 colonies/tree at petal fall for peach, and 1 colony/tree for nectarine. The best way to scout for aphids during bloom is with a <a href="https://www.youtube.com/watch?v=FVETlObhsIs">beating tray</a>. Blossoms may also be collected, opened, and examined for the presence of aphids using a hand lens. This is particularly important for nectarine blocks. Check 10 trees per block with the beating tray. Collect 50 blossoms per block and examine for the presence of aphids. If more than 1 colony of aphids are found in nectarines, or 2-3 colonies are found in peaches, an insecticide for aphids will be needed when all petals are off. See the <a href="https://njaes.rutgers.edu/pubs/publication.php?pid=E002">NJ Commercial Tree Fruit Production Guide for recommended materials and rates</a>. No aphid activity has been noted on southern counties to date.</p><p><strong>Plum Curculio; Tarnished Plant Bugs; and Other Catfacing Insects:</strong> Plum Curculio start to move into orchards at about <a href="https://plant-pest-advisory.rutgers.edu/plum-curculio-phenology-model/">88-100 degree days base 50 after January 1</a>. Applications for PC should be initiated once <strong><em>all petals are off</em></strong>, with a second application made with ovicidal materials at 379-402 DD. Currently we have accumulated about 103 DD base 50 in southern counties. Growers can monitor degree day development at their site by finding the nearest weather station and using the <a href="https://newa.cornell.edu/degree-day-calculator/">degree day development tool at NEWA</a>. Catfacing insects are starting activity but cause little damage at this time of the year. Catfacing insects will become more of an issue as temperatures warm and mowing and other ground cover activities become more common <strong><em>after bloom</em></strong>. Insecticides for catfacing insects and plum curculio <strong><em>are not recommended until after all petals are off</em></strong>.</p><p><strong>Scale Insects: </strong>Dormant oil applications are standard recommendations for scale control, but in some years conditions are not good for oil and control is less than desired. Where scale has been recurring the application of Movento at petal fall to shuck split has “cleaned up” chronic scale outbreaks. Movento should be applied at 6-9 ozs/ac. a penetrant must be included as described on the product label. Movento will also control green peach aphid at this timing.</p><p><strong>Lesser and Greater Peach Borer: </strong>Mating disruption dispensers for borers should be deployed in early May. See the <a href="https://njaes.rutgers.edu/pubs/publication.php?pid=E002">NJ Commercial Tree Fruit Production Guide for recommended dispensers and rates</a>.</p><p><strong>Apples and Pears:</strong></p><p><strong>Diseases:</strong> Fire Blight, Apple Scab, Rust diseases, and Powdery Mildew are the main targets at this stage. The <a href="https://newa.cornell.edu/index.php?page=apple-diseases">NEWA apple scab model</a> is estimating about 40% ascospore maturity as of 4/12 in southern NJ with 38 % of cumulative ascospores discharged. Northern counties were at Green tip on or about 3/18. The model estimates about 22% ascopsore maturity for Northern Counties with only 21% ascospores released. Primary apple scab spores are released during any substantial <a href="https://web.uri.edu/ipm/2013/05/mills-table-apple-scab-infection-periods/">infection period</a>. More information can be found in <a href="https://extension.psu.edu/2024-disease-update-apple-scab-and-brown-rot-blossom-blight-conditions-predicted-for-april-10-april-12">this blogpost from Penn State</a>. Between tight cluster and first cover include products effective for powdery mildew and cedar apple rust. To manage Fire Blight in both apples and pears, consider using Kasumin at bloom. Kasumin is an antibiotic like Streptomycin and Oxytetratracycline. It contains Kasugamycin which is a different chemistry. Kasumin is only labeled for bloom and petal fall applications while strep and oxytet are labeled for post bloom use (<strong><em>note that Fireline 45 only allows for 1 postbloom application on apple)</em></strong>. Using 3 different chemistries in rotation allows for resistance management while extending the protection into the post bloom period when late blossoms typically appear which ever material you use, the addition of Actigard or other plant defense elicitors may improve control.</p><p><strong>Rust Diseases: </strong>The two most common rust diseases that affect pome fruit are Quince Rust and Cedar Apple Rust. In some years these diseases can be troublesome in commercial orchards. Most disease control programs for scab will also control rust. In organically managed blocks in the east options are limited for approved materials that are effective for rust. Potassium Bicarbonate products have shown good efficacy for rust diseases in trials performed in Virginia. Organic growers should seek out and plant rust resistant cultivars. Cultural controls are not practicable due to the widespread presence of alternate host Junipers both wild and cultivated. Rust disease development on junipers should now be producing large spore releases during wetting periods. See this <a href="https://blogs.cornell.edu/plantpathhvl/apple-diseases/rust-diseases/">link for pictures of rust </a>on pome fruit and juniper.</p><p><strong>Scale Insects: </strong>Dormant oil applications are standard recommendations for scale control, but in some years conditions are not good for oil and control is less than desired. Where scale has been recurring the application of Movento at petal fall to shuck split has “cleaned up” chronic scale outbreaks. Movento should be applied at 6-9 ozs/ac. a penetrant must be included as described on the product label. Movento should also control rosy apple aphid at this timing.</p><p><strong>Rosy Apple Aphid: </strong> If a pre-bloom application was not made, monitor for colonies during bloom and use a treatment threshold of 1 colony/tree at petal fall. See the <a href="https://njaes.rutgers.edu/pubs/publication.php?pid=E002">NJ Commercial Tree Fruit Production Guide for recommended materials and rates</a>.</p><p><strong>Pear Psylla: </strong> Dormant oil applications should have already been started to deter psylla egg laying. At the green cluster stage a pyrethroid or Esteem is generally included with oil. Pyrethroids may knock down some of the adults migrating into the orchard, while Esteem may sterilize them. In lieu of oil or insecticides, Surround may also be applied starting at swollen bud and continued through petal fall. If using Surround through the bloom period stop at petal fall and switch to applications of 1% summer oil @ 1gal/ac in no less than 150 gals/ac. these should be made at no more than 2 week intervals. At petal fall insecticide options for Psylla control include Actara, Assail, Belay, Movento, Sivanto Prime, and Agri-mek. See the <a href="https://njaes.rutgers.edu/pubs/publication.php?pid=E002">NJ Commercial Tree Fruit Production Guide for recommended materials and rates</a>.</p><p><strong>Pear Diseases:</strong> Include effective materials such as Ziram or EBDC formulations for Pear Scab and Rust diseases beginning at the cluster bud stage. At white bud use products effective for pear scab, rusts, <strong><em>and</em></strong> fabrea leaf spot. For both apples and pears, consider using Kasumin at bloom. Kasumin is an antibiotic like Streptomycin and Oxytetratracycline. It contains Kasugamycin which is a different chemistry. Kasumin is only labeled for bloom and petal fall applications while strep and oxytet are labeled for post bloom use. Using 3 different chemistries in rotation allows for resistance management while extending the protection into the post bloom period when late blossoms typically appear. whichever material you use, the addition of Actigard or other plant defense elicitors may improve control.</p><p><strong>Grapes: </strong>Grapes are at budbreak to the 1″ stage of development. The most important disease to manage at this time is Phomopsis. Insect pests to monitor are <a href="https://www.canr.msu.edu/ipm/diseases/grape_flea_beetle">Grape Flea Beetle</a>, and <a href="https://grapes.extension.org/climbing-cutworms/">Climbing Cutworms</a>. Controls for these insects are rarely needed. If control is determined to be necessary, use one of the materials recommended in the <a href="https://njaes.rutgers.edu/pubs/publication.php?pid=E283">New Jersey Commercial Grape Production Guide</a>.
