Late-July Nectarine Varieties for New Jersey – New and Standard
Fruit IPM Report July 29, 2025
Peach:
Diseases: Brown rot: Brown rot is appearing in ripening fruit throughout the state. Highly effective rot materials such as DMI’s (FRAC group 3) and Strobilurins (FRAC group 11) should be applied beginning 3 – 4 weeks prior to harvest. See the NJ Commercial Tree Fruit Production Guide for more information.
Tarnished Plant Bugs; and Other Cat-facing Insects: Cat-facing insects remain active in orchards. The percent fruit injury observed remains low (average <1%).
Oriental Fruit Moth: A biofix point for OFM was set on 4/2 for southern counties and 4/17 in northern counties. See below for timings for third generation.

Scale Insects: Numbers of scale crawlers on traps in southern county orchards are increasing indicating the second generation has emerged (Figure 1).
Crawler emergence will continue through August. Esteem and Centaur are both good scale materials that should be applied at the start of crawler emergence. These materials should only need one application. Other options include: Assail, Belay, Actara (Group 4A): Closer (Group 4C); Sivanto (Group 4D) and Venerate. These products may need more than one application. Venerate is a good option as a pre-harvest treatment with a 0-day PHI.
Japanese Beetles: Japanese beetles and June bugs have been observed feeding on fruit throughout the state. 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 maturing apple fruit.
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. Adult male 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.

Grape: Grapes are beginning veraison in southern counties. Third generation grape berry moths are actively flying and larvae have been observed feeding in grape bunches.
Figure 3. Downy mildew on the underside of a grape leaf.
Refer to the Commercial Grape Pest Control Recommendations for New Jersey for management options. Spotted lanternfly adults are now being reported in vineyards in southern NJ. Japanese beetles are actively feeding on foliage. Stink bugs have also been observed in vineyards in southern counties. Disease management continues to focus on downy mildew (Figure 3).
Blueberry: Spotted-wing drosophila trap captures remain high at an average of 52 males and 35 in Atlantic and Burlington Counties, respectively. Treatments for spotted-wing drosophila should continue on a 7-day schedule where susceptible fruit remain in the field. 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.

Mid-July Nectarine Varieties for NJ – Silvergem, Silverglo, Easternglo, and Avalon
There are four excellent, yellow and white-fleshed nectarine varieties harvested during mid-July. These varieties were developed at the Rutgers Fruit Breeding program and evaluated over the years at multiple Southern New Jersey locations. The ripening days could be a few days later for central and northern New Jersey. [Read more…]

Mid-July Peach Varieties – Gala, PF 8 Ball, Summer Serenade, July Rose, and PF Lucky 13
GALA is a medium to medium-large, globose, 70-90% scarlet red over yellow-orange ground color, yellow-fleshed, semi-freestone peach ripening July 11-15, about a week after the Sentry. The flesh is firm, with a sweet and mildly tangy flavor. The tree is vigorous and moderately productive. Note that these varieties were evaluated in southern New Jersey; as a result, the harvest dates could be a few days later for the Central and Northern New Jersey orchards.
Challenges: Gala is a beautiful peach in a great season, but the size and yield could be highly variable. Split pits are a problem even in a normal year, and the first pick may have significant split pits. Fruit has medium susceptibility to bacterial spot.
FLAMIN FURY® PF#8 BALL is a large, globose, 70-90% crimson red over greenish-yellow ground color, yellow-fleshed semi-clingstone peach with prominent suture groove, ripening during July 13-18. The fruit is firm, with melting, sweet, juicy flesh, and has a sweet and tangy flavor. The tree is spreading, vigorous, and productive, with medium susceptibility to bacterial spots. A promising variety because of its color and size. A good option to replace Gala peach.
SUMMER SERENADE is a medium-large, globose to ovate, attractive, 50-70% crimson red over yellow-green ground color, yellow-fleshed, semi-clingstone peach ripening from July 13-16, approximately 11 days before Redhaven. The flesh is firm with fair to good flavor. The tree is moderately vigorous and productive, with low susceptibility to bacterial spot. Summer Serenade has a better size than Garnet Beauty and PF 7, with a significant suture groove and flavor like Garnet Beauty.
JULY ROSE is a popular white fleshed peach with excellent firmness, cling stone, and low fuzz. Fruit is large and attractive, and ripens between Sugar May and White Lady from 15-20 July. Fruit is always very sweet and sub-acid. It has good fruit and leaf resistance to bacterial leaf spot. Even poorly thinned trees tend to produce large-sized fruit. Moderate fruit or bloom thinning will be required to optimize size and quality. Fruit hangs well and has better cold-hardiness than other white varieties.
Snowbrite is a good white-fleshed peach that ripens a few days after July Rose but is highly susceptible to bacterial spots. Scarlet Pearl is another good white-fleshed peach. However, it is a cold, tender variety and produces split pits.
FLAMIN FURY PF LUCKY 13 is a large, globose to slightly ovate, heavy scarlet red over orange-yellow ground color, yellow-fleshed, freestone peach ripening near or earlier than Redhaven. The flesh is crunchy, firm, and sweet and tangy. The tree is vigorous and productive, with slight drop and inking tendencies and low to moderate susceptibility to bacterial spots. This very attractive peach has also shown good size and minimal splits.

|||||||||||||||||||||||||
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.

Grape: The next timing for Grape Berry Moth will be on or about 7/22 if using Intrepid, Altacor or other diamides in southern counties. Growers using other insecticides can make applications a few days later. Spotted lanternfly adults are now being reported in vineyards in southern NJ (Figure 3).
Japanese beetles are actively feeding on foliage. Observations of downy mildew have increased from the previous week.
Blueberry: 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.
Fruit IPM Report July 14, 2025
Peach:
Figure 1. Early cat-facing injury on peach.
Brown rot: 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: Tarnished plant bug and stink bugs are active and present at moderate to high levels in some orchards. The percent fruit injury observed remains low (average <1%) but has increased from previous weeks (Figure 1).
Oriental Fruit Moth: A biofix point for OFM was set on 4/2 for southern counties and 4/17 in northern counties. See below for timings for third generation.
|
|||||||||||||||||||||||||
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 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.

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.
