Fields of Devotion film screening at 2023 New Jersey Agricultural Convention & Trade Show at Harrah’s Resort in Atlantic City, on Tuesday February 7th.
Fields of Devotion (30 minutes) features New Jersey farmers and Rutgers scientists partnering to develop climate resilient and disease resistant food crops to empower growers.
Discussion with the featured farmers and scientists immediately following screening.
Watch the Fields of Devotion trailer by clicking here.
Event description: Small family farms in New Jersey are racing against climate change. Unpredictable weather and new diseases are threatening the very crops they depend upon. Fields of Devotion follows the decade long partnership between Rutgers plant biologists, the New Jersey Agricultural Experiment Station (NJAES), and New Jersey herb farmers who together developed lines of sweet basil resistant to downy mildew, a devastating disease destroying Ocimum species around the world.
Building upon more than a century of Rutgers’ support for New Jersey growers, Fields of Devotion is told from the perspective of the farmers and graduate science students who together help realize Rutgers land grant mission of community engagement and academic excellence.
For those attending the New Jersey Vegetable Growers Association (NJ-VGA) or the New Jersey Department of Agriculture’s (NJDA) 2023 Annual Meeting we cordially invite you to please join us this February 7th at 3:30 pm in Wildwood Rooms 8 and 9.

Vegetable Disease Update – 5/27/20
- Sand blasting has been reported on a number of leafy green and other crops these past few weeks. Injury from sand blasting predisposes plants to bacterial infections. Remember, all bacteria need a wound or a natural opening, such as a stomata, to gain entry into the plant. Fields with extensive injury need to be scouted regularly, and most likely will need to be sprayed regularly with a copper fungicide or disinfectant-type product to help mitigate infection and spread.

- Bacterial leaf spot has been reported in sweet basil. BLS of sweet basil is a relatively new disease of basil in the US. The bacterium has a large host range and can survive and overwinter in the soil on infested plant debris. Disease development is favored by hot, humid, rainy weather. Periods of hot, dry weather will help mitigate disease development.
- Club root has been reported in southern New Jersey.
- Cucurbit powdery mildew season is quickly approaching as more cucurbit crops are planted. For a review of CPM control strategies please click here.
- Cucurbit downy mildew has been reported as far north as southern Georgia on cucumber and cantaloupe. To track the progress of CDM please visit the CDM forecasting website.
- With the on and off again rains we have been getting, along with warmer weather this week, all growers should consider applying at-transplanting fungicides for root rot control. Please click here to see this article.
- Weather conditions have been ideal for fruit rot infections in strawberries. For more information on controlling fruit rots in strawberry please click here.
- The following is a nice article by Jeanine Davis from NCSU about mixing Serenade with coppers.
- The 2020/2021 Commercial Vegetable Production Recommendations Guide is available for free online! With many county offices running reduced hours or being closed this is the easiest way to obtain the newest recommendations.

Veg IPM Update: Week Ending 6/29/16
Sweet Corn
European corn borer (ECB) moth catches remain very low now. The first flight is over, and growers are now managing subsequent infestations, which are generally lower than normal. Present adult activity is too low to generate a map image (<0.5 moths/night in all traps). Larval feeding ranges from single digits to above 20% in areas where IPM personnel are operating, although many plantings still have no detectable feeding at all. Be sure to begin monitoring plantings for ECB feeding while they are still in the whorl stage. Consider treating when the number of infested plants in a 50 plant sample exceeds 12%. Feeding in the whorl stage will appear as numerous small holes (called “shot-hole”) on leaves, with damage present on consecutively younger leaves. As plants progress to pre-tassel and beyond, droppings and larvae may be found in or on the emerging tassels. Any planting remaining at or above threshold as it proceeds to full tassel should be treated, as this is the last stage at which ECB larvae will be exposed and vulnerable to insecticidal sprays. Insecticides that are acceptable in organic production include the spinosyn based material Entrust (IRAC-5) and Dipel (IRAC-11a). The 10G formulation of Dipel is particularly useful when granules can be dropped or broadcast such that they get into the whorls of corn plants. Other effective insecticides include Coragen (IRAC 28), and the synthetic pyrethroids (IRAC 3). See the 2016 Commercial Vegetable Recommendations Guide for a more complete list of insecticides.
The highest nightly ECB catches for the previous week are as follows:
| Denville 1 | Matawan 1 |
| Farmingdale 1 | New Egypt 1 |
| Lawrenceville 1 | Old Bridge 1 |
| Little York 1 | Pennington 1 |
In addition, several low-level infestations of fall armyworm (FAW) were discovered this week. These were in Hunterdon and Middlesex counties, but it is likely that there are other light infestations throughout the state. These infestations have not exceeded 4% in the whorl stage, and are likely the result of a few FAW moths arriving in advance of weather fronts. This is somewhat early for FAW infestations in NJ, and we would expect to see little injury until mid-July. FAW feeding is much more obvious than that of ECB larvae, with large ragged holes and conspicuous droppings found in the whorl. FAW is resistant to synthetic pyrethroid insecticides (IRAC 3), and can be effectively managed with insecticides such as Radiant/Entrust/Blackhawk (IRAC 5) or Coragen/Besiege (IRAC 28). Consider treating if damage from ECB and/or FAW reaches 12%. [Read more…]

Vegetable Disease Briefs – Late blight reported, 9/8/14
- Late blight was confirmed in an organic cherry tomato field near Lawrenceville, NJ in Mercer County on 9/8. All tomato growers should continue to scout on a daily basis. Weather conditions have been ideal with the heavy, scattered rain and humid conditions over the past few days across much of the state.
- There have also been scattered reports of late blight have been reported in PA and VA over the past couple weeks.
- Conditions for downy mildew development on many crops have been ideal this past week with the scattered heavy rains, cooler night temperatures and dewy mornings. Downy mildew has been reported on cucumber, basil, and crucifer crops in our area. Remember, the fungicides recommended for controlling downy mildew are specific and need to be incorporated into weekly maintenance applications.
- Cucurbit powdery mildew remains active on many cucurbit crops.

Vegetable Disease Update – 8/9/13
No Late blight has been reported in New Jersey this week.
Cucurbit downy mildew has been found on pumpkin in northern New Jersey.
Phytophthora blight remains active in many crops. The good news is that next week should bring some dry weather.
An early indication from our pepper bacterial leaf spot differential trial is that Race 6 is present in southern New Jersey. We’ll have more information later this fall.
Phomopsis leaf spot has been found on Italian eggplant. [Read more…]
