Veg IPM Update 7/25/25

Greetings from the Veg IPM team!

Sweet Corn

Corn earworm moth captures are increasing, leading to 3- or 4-day spray intervals being needed throughout the state. When temperatures are high (>85 degrees F), shorten the spray interval by one day. Rotation is important for avoiding resistance, and there are four IRAC groups that are registered in silking sweet corn: 1 (carbamates), 3 (pyrethroids), 5 (spinosyns), and 28 (diamides). Corn earworm is at least partly resistant to several pyrethroids, so a spray program should not rely solely on pyrethroids, although they can be useful in tank-mixes or as pre-mixed products, such as Besiege or Elevest (Group 28 + Group 3). For detailed information about resistance and potential spray programs, the University of Delaware has an excellent resource on corn earworm management.

Spray intervals based on nightly pheromone moth captures for the southern part of New Jersey. Note that not all locations in the IPM program are currently trapping. This map is based on the following thresholds: 0 moths = 6-7 day schedule, 1 moth = 5 day spray schedule, 2-20 moths = 4 day spray schedule, 20+ moths = 3 day spray schedule.

 

Fall armyworm (FAW) infestations are beginning to pick up in some locations. Young larvae will cause damage known as “window paning”, in which the top surface of the leaf is eaten away, leaving behind thin, white, membranous-looking scratch marks. As the larvae age, these feeding marks become more ragged (A). The damage can look somewhat similar to European corn borer feeding, but FAW damage will be more severe and will lead down into the whorl. The caterpillars will have a dark head capsule with a distinct, inverted Y-shaped suture (B). We recommend using products other than diamides (IRAC Group 28) when treating whorl-stage infestations, as diamides are important to save for silk protection. Effective products include Lannate (Group 1A), Radiant (Group 5), Intrepid (Group 18), Intrepid Edge (5+18), and Avaunt (Group 22). Note that Avaunt can only be used through tassel push.

We are seeing a significant amount smut it sweet corn. Normally, smut infects the ears, however we have seen smut growths on vegetative stages (leaves and tassels) as well. Smut was prevalent in our area in 2024, and you can read more about it in an update written last year. Smut is rarely economic and there are no effective treatments for it. Being able to correctly identify it can help rule out other plant problems.

Tomatoes

Throughout New Jersey we’re continuing to see high thrips counts both in tunnels and in the field, although numbers have been higher in tunnels. We consider more than 5 thrips on 10 leaves a high count. Other guides suggest 3-5 thrips per flower or the presence of stippling damage on fruit to be a treatment threshold. Thrips management is especially important because of their ability to vector tomato spotted wilt virus (TSWV), a growing concern in New Jersey where we have resistance-breaking strains. We have seen several locations in our scouting program with small outbreaks of TSWV (in both peppers and tomatoes) so far. Scouting and roguing out these plants while continuing to manage thrips should help prevent serious losses. Additionally, follow best management practices for reducing TSWV risk throughout the season.

Caterpillar pests have begun showing up in throughout the state. We’ve seen some fruit damage, and tomato fruitworm (AKA corn earworm), beet armyworm, and hornworms on plants and fruit. There are no reliable thresholds for determining when to spray for these caterpillar pests, however scouting and consulting the corn earworm pressure map for the state will help give a sense of risk to the crop. When corn earworm pressure indicates a 3 or 4 day spray interval in corn (2-20 moths per night) as is currently the case in much of the state, tomatoes should be scouted weekly for feeding damage. Pyrethroid resistance is widespread in tomato fruitworm/corn earworm and beet armyworm, so other classes of insecticides should be used if management is needed.

With consistent hot temperatures, we’re seeing more spider mites in tomato plantings. Spider mites tend to be worse in hot, dry conditions, and especially thrive in tunnels. Their populations often dramatically increase following broad-spectrum insecticides, which reduce their natural enemies. The first sign of their presence is often light-colored stippling seen on the top surface of tomato leaves. The mites causing this damage are usually found on the undersides of leaves. For spider mites, Nealta (IRAC 25) and Oberon (IRAC 23) are effective materials that are more friendly to beneficial insects, but Portal (IRAC 21A) and other materials can also be used to manage populations.

Peppers

In terms of most insect pests, peppers have been looking very good. We have seen aphids, spider mites, and thrips at low levels so far, however it’s important to keep in mind that thrips can transmit TSWV to peppers as well, and so monitoring and staying on top of thrips populations is crucial. As with tomatoes, finding and roguing out infected plants is important as well. See previous section for an example of TSWV symptoms in peppers.

Anthracnose on ripe pepper fruit. Note concentric circles and sporulation. Picture by Maria Cramer.

With drying weather, peppers have been fairly disease-free, but we have seen instances of anthracnose. Anthracnose is an important disease to scout for and be able to identify as removing infected fruit and strip-picking surrounding fruit is key to managing its spread. Your fungicide program can also help manage anthracnose — for more information, read more here.

As a reminder, in June we saw several pepper weevils on pepper weevil traps in Cumberland and Salem Counties. Read more about pepper weevil biology and management here. If you think you may have pepper weevil on your farm or are interested in monitoring, please contact Maria Cramer.

Cole Crops 

We are no longer seeing many flea beetles in cole crops, but we continue to see caterpillar activity. Treatment thresholds vary between crops and growth stage, but for heading cole crops between early vegetative and cupping, the treatment threshold is 30%. As heads form, the treatment threshold goes down to just 5% infestation. Sprayable Bt products (IRAC 11A) such as Dipel, Xentari, or Javelin can be effective on young imported cabbage worm caterpillars. Other materials approved for caterpillar control include Entrust/Radiant (IRAC 5), Proclaim (IRAC 6), Torac (IRAC 21A), and Exirel (IRAC 28). Diamondback moth (the primary caterpillar found in southern NJ) has resistance to many insecticide groups, and pyrethroids (IRAC 3A) are not effective for their management. For Bt products and contact insecticides, coverage on the undersides the leaves is essential.

Pumpkins and Other Cucurbits

Cucurbit downy mildew was first reported on 7/11/25 on cucumbers in central NJ and has been found on cucumbers and cantaloupe at the Snyder Research Farm in Pittstown. Growers should be applying protectants on cucumbers and cantaloupes for cucurbit downy mildew at this time. As of this post, we haven’t found any instances of the disease on pumpkins, squash, or watermelon. For information on how to build an effective cucurbit down mildew control program, please reference this post by Dr. Andy Wyenandt and consult the Mid-Atlantic Production Guide for additional materials that can be used.

In pumpkins, we’ve seen few insect issues, although adult squash bugs and egg masses are starting to appear. Consider treating for squash bug if you see more than one egg mass or group of nymphs per plant (see photos below).

Powdery mildew is also beginning to pick up. If more than one leaf in a 50 leaf sample is infected, fungicide programs for powdery mildew should be initiated.

We have also seen isolated cases of anthracnose, bacterial wilt, plectosporium, and phythophthora root rot. A preventative diseases management plan based on recommendations from the Mid-Atlantic Production Guide is important for suppressing many of these diseases. If you suspect diseases in your pumpkins (or other cucurbits), reference the “Diagnosing important diseases in Cucurbit crops” guide or send/bring samples to Rutger’s Plant Diagnostic Lab.

As always, please consult the Mid-Atlantic Commercial Vegetable Production Guide for a comprehensive list of materials that are labeled for specific crops and pests. As always, be sure to follow label rates and application instructions.

Scale Insects: Second generation White Peach Scale crawlers should emerge sometime this week or next. Second generation San Jose Scale crawlers emerge about 7/17 +/- 8 days. Esteem is a good scale material that has a 14-day PHI for stone fruit. Centaur is also effective, has a 14-day PHI and can be used only once during the growing season. Venerate has shown efficacy as a pre-harvest treatment against scale and has a 0-day PHI. If using Venerate to control scale insects, make 2 applications 7 days apart starting a week after crawler emergence.

Japanese Beetles: Japanese beetles and June bugs have been observed feeding on fruit in southern counties. Adults are attracted to ripening fruit. Insecticides that are effective against Japanese beetles and june bugs are products that contain imidacloprid (Admire pro and Leverage 360), Danitol, and Sevin.

Apples and Pears:

Figure 2. Bitter rot infection on apple.

Diseases: Various rots but mostly bitter rot is present in orchards throughout the state (Figure 2).

Research has suggested products such as Merivon, Luna Sensation, Inspire Super, Omega, and Aprovia are effective rot materials to be alternated with broad-spectrum fungicides such as captan and ziram. Phosphorous acid products such as Prophyt or Rampart can be added to captan sprays to improve control.

Brown Marmorated Stink Bugs: Brown Marmorated Stink bugs are being captured at low levels in orchards statewide. Both adults and nymphs are present. See the NJ Tree Fruit Production guide for effective materials.

Codling Moth (CM): Second generation timings are updated below. Trap captures continue and increased slightly in some southern county orchards last week. Additional applications should be made if trap captures exceed 5 moths/trap.

Japanese Beetles: Japanese beetle activity has increased in orchards throughout the state. Products containing imidacloprid are standard insecticides for Japanese beetle control and have a short PHI. See the NJ Commercial Tree Fruit Production Guide for more information.

Apples and Pears:

Diseases: Now that primary scab has ended, the focus turns toward summer diseases such as fruit rots (esp. Bitter rot), and sooty blotch and fly speck. Bitter rot control has been difficult at best in recent years even where management programs have been rigorous. Research has suggested products such as Merivon, Luna Sensation, Inspire Super, Omega, and Aprovia may be effective, and longtime reliable broad-spectrum fungicides such as captan and ziram should provide control. Experience has suggested that the addition of phosphorous acid products such as Prophyt or Rampart to captan sprays may improve control. Observations are that these products improve control of other summer diseases such as sooty blotch and flyspeck, and may help suppress scab infections where present. Fungicides should be applied every 10-14 days, or consider reapplication after 2 inches of rainfall. Bitter rot symptoms have been observed in both southern and northern counties.

Grape: The next timing for Grape Berry Moth will be on or about 7/22 for Intrepid or Diamides, or a few days later for other insecticides based on the biofix of May 19 in southern counties.

Figure 3. Downy mildew on grape.

Treatments for the third generation are at an accumulation of 1620 degree days (base 47.14). Spotted lanternfly adults were reported last week in vineyards in southern NJ. See this previous Plant & Pest Advisory post on Management of Spotted Lanternfly in New Jersey Vineyards. Also, Japanese beetle pressure is increasing in vineyards throughout the state. See the NJ Commercial Grape Production Guide for more information on insecticides effective for JB.

Diseases: Wet, warm and humid weather has been conducive for infections from Downy mildew. Dr. Mizuho Nita at Virginia Tech provides a comprehensive update and summary of diseases from bloom to harvest.

Blueberry: Spotted-wing drosophila (SWD) numbers have increased from previous weeks. Treatments for spotted-wing drosophila should continue on a 7-day schedule. For management recommendations, refer to Commercial Blueberry Pest Control Recommendations for New Jersey. For weekly reports on blueberry pests and recommendations read the Rutgers Blueberry Bulletin.

Veg IPM update 7/11/25

Greetings from the Veg IPM team!

Sweet Corn

Corn earworm moth captures are increasing in the southern part of the state leading to 3- or 4-day spray intervals being needed at all trapping locations south of interstate 195. When temperatures are high (>85 degrees F), shorten the spray interval by one day. Rotation is important for avoiding resistance, and there are four IRAC groups that are registered in silking sweet corn: 1 (carbamates), 3 (pyrethroids), 5 (spinosyns), and 28 (diamides). Corn earworm is at least partly resistant to several pyrethroids, so a spray program should not rely solely on pyrethroids, although they can be useful in tank-mixes or as pre-mixed products, such as Besiege or Elevest (Group 28 + Group 3). For detailed information about resistance and potential spray programs, the University of Delaware has an excellent resource on corn earworm management. We’ve also seen some very minor instances of European corn borer, fall armyworm, and corn earworm feeding in pre-silking corn. In the pre-tassel stage, we use a treatment threshold of 12% infestation of these types of caterpillars, and sightings have been far below this so far.

Spray intervals based on nightly pheromone moth captures for the southern part of New Jersey. Note that not all locations in the IPM program are currently trapping. This map is based on the following thresholds: 0 moths = 6-7 day schedule, 1 moth = 5 day spray schedule, 2-20 moths = 4 day spray schedule, 20+ moths = 3 day spray schedule.

Tomatoes

Throughout New Jersey we’re continuing to see high thrips counts both in tunnels and in the field, although numbers have been higher in tunnels. We consider more than 5 thrips on 10 leaves a high count. Other guides suggest 3-5 thrips per flower or the presence of stippling damage on fruit to be a treatment threshold. Thrips management is especially important because of their ability to vector tomato spotted wilt virus (TSWV), a growing concern in New Jersey where we have resistance-breaking strains. We have seen several locations in our scouting program with small outbreaks of TSWV (in both peppers and tomatoes) so far. Scouting and roguing out these plants while continuing to manage thrips should help prevent serious losses. Additionally, follow best management practices for reducing TSWV risk throughout the season.

Top picture shows curled tomato leaf with brown circles covering it. The bottom picture shows a pepper plant with distorted, slightly cupped leaves, and yellow markings, including circles, on many leaves.

A) TSWV on a tomato leaf. Note the circle-shaped brown lesions. B) TSWV on a pepper plant. Note the distortion of leaves all over the plant as well as the yellow wavy lines and circles visible on leaves. Photos by Maria Cramer.

Caterpillar pests have begun showing up in southern NJ plantings in the last week. We’ve seen some fruit damage, and tomato fruitworm (AKA corn earworm), beet armyworm, and hornworms on plants and fruit. There are no reliable thresholds for determining when to spray for these caterpillar pests, however scouting and consulting the corn earworm pressure map for the state will help give a sense of risk to the crop. When corn earworm pressure indicates a 3 or 4 day spray interval in corn (2-20 moths per night) as is currently the case in much of the state, tomatoes should be scouted weekly for feeding damage. Pyrethroid resistance is widespread in tomato fruitworm/corn earworm and beet armyworm, so other classes of insecticides should be used if management is needed.

With consistent hot temperatures, we’re seeing more spider mites in tomato plantings. Spider mites tend to be worse in hot dry conditions, and especially thrive in tunnels. Their populations often dramatically increase following broad-spectrum insecticides which reduce their natural enemies. The first sign of their presence is often light-colored stippling seen on the top surface of tomato leaves. The mites causing this damage are usually found on the undersides of leaves. For spider mites, Nealta (IRAC 25) and Oberon (IRAC 23) are effective materials that are more friendly to beneficial insects, but Portal (IRAC 21A) and other materials can also be used to manage populations.

Tomato leaves with tiny yellow or white dots on visible on the top surface of the leaf.

Spider mite stippling visible when looking at tomato leaves from above. The spider mites are found on the undersides of the leaves. Photo by Maria Cramer.

We’re also seeing limited aphid activity in tomatoes. If dealing with primarily aphids, products such as Beleaf (IRAC 29) are recommended, especially if plants have reached the flowering stage. However, natural enemies often control aphids, so if counts are low and natural enemies like lacewings, lady beetles, or parasitoid wasps are present, you may avoid sprays.

Peppers

In terms of most insect pests, peppers have been looking very good. We have seen aphids, spider mites, and thrips at low levels so far, however it’s important to keep in mind that thrips can transmit TSWV to peppers as well, and so monitoring and staying on top of thrips populations is crucial. As with tomatoes, finding and roguing out infected plants is important as well. See previous section for an example of TSWV symptoms in peppers.

As a reminder, in June we saw several pepper weevils on pepper weevil traps in Cumberland and Salem Counties. Read more about pepper weevil biology and management here. If you think you may have pepper weevil on your farm or are interested in monitoring, please contact Maria Cramer.

Cole Crops 

We are no longer seeing many flea beetles in cole crops, but we continue to see caterpillar activity. Treatment thresholds vary between crops and growth stage, but for heading cole crops between early vegetative and cupping, the treatment threshold is 30%. As heads form, the treatment threshold goes down to just 5% infestation. Sprayable Bt products (IRAC 11A) such as Dipel, Xentari, or Javelin can be effective on young imported cabbage worm caterpillars. Other materials approved for caterpillar control include Entrust/Radiant (IRAC 5), Proclaim (IRAC 6), Torac (IRAC 21A), and Exirel (IRAC 28). Diamondback moth (the primary caterpillar found in southern NJ) has resistance to many insecticide groups, and pyrethroids (IRAC 3A) are not effective for their management. For Bt products and contact insecticides, coverage on the undersides the leaves is essential.

Two caterpillars on brassica leaves. Diamondback moth caterpillar on the left is smooth and tapered at each end. Imported cabbageworm on the right is fuzzy.

Left: Diamondback moth caterpillar, showing characteristic tapering at each end. Right: Imported cabbageworm caterpillar showing characteristic fuzziness. Pictures by Maria Cramer.

Pumpkins

So far pumpkins have looked very clean in terms of insects. We have seen isolated cases of anthracnose, bacterial wilt, plectosporium, and phythophthora root rot. A preventative diseases management plan based on recommendations from the Mid-Atlantic Production Guide is important for suppressing many of these diseases. If you suspect diseases in your pumpkins (or other cucurbits), reference the “Diagnosing important diseases in Cucurbit crops” guide or send/bring samples to Rutger’s Plant Diagnostic Lab.

As always, please consult the Mid-Atlantic Commercial Vegetable Production Guide for a comprehensive list of materials that are labeled for specific crops and pests. As always, be sure to follow label rates and application instructions.

Fruit IPM Report July 7, 2025

Peach:

Figure 1. Brown rot on mature fruit. Entire surface of lesion is covered with spores.

Brown Rot:  Warm and wet weather this summer have been ideal conditions for brown rot to develop on fruit (Figure 1). Most growers should be relying on a captan based program for mid-season covers, followed by better materials during the last 3 weeks pre-harvest. For reference see Dr. Norm Lalancette’s post Improving Your Late Season Peach Brown Rot Control Program — Plant & Pest Advisory.

Tarnished Plant Bugs; and Other Cat-facing Insects: Cat-facing insect activity is increasing with the arrival of hot weather and is present at moderate to high levels in some orchards.

Scale Insects: Second generation White Peach Scale crawlers should emerge sometime this week or next. Second generation San Jose Scale crawlers emerge about 7/17 +/- 8 days. Esteem is a good scale material that has a 14-day PHI for stone fruit. Centaur is also effective, has a 14-day PHI and can be used only once during the growing season. Venerate has shown efficacy as a pre-harvest treatment against scale and has a 0-day PHI. If using Venerate to control scale insects, make 2 applications 7 days apart starting a week after crawler emergence.

Japanese Beetles: Japanese beetle activity has been noticeable in many orchards. Products containing imidacloprid are standard insecticides for Japanese beetle control and have a short PHI. See the NJ Commercial Tree Fruit Production Guide for more information.

Apples and Pears:
