NEWA Disease and Insect Forecasting System
The NEWA (Network for Environment and Weather Applications) website managed by the New York state Integrated Pest Management (IPM) program can be found at http://newa.cornell.edu/. The website is easy to use and offers weather data as well as insect and disease forecasting (e.g., P-days for Early blight and BlightCast for Late Blight in potato, and Tom-Cast DSV’s for Early blight, Septoria leaf spot and Anthracnose fruit rot in tomatoes. Just click on the map and scroll down to New Jersey and chose a weather station within the closest proximity to your operation. Once you choose a location a new webpage will appear with the different forecasting options to choose from. Clicking on the potato early blight will automatically generate daily and accumulative P-day values for you for that location. Remember once 300 P-days are accumulated, spray programs for early blight control should be initiated. Clicking on either tomato or potato Late blight will bring up a table which will provide daily rainfall, average temperature, hours above 90% RH and daily and accumulative DSV values for that location. One important thing to remember for the disease forecasting is to track the accumulation of DSV or P-day values based on when you transplanted tomatoes or when potatoes emerged on your farm.

New Jersey Farmland Preservation Seeking New Applications for State Acquisition Program
New Jersey Secretary of Agriculture Douglas H. Fisher recently announced that the New Jersey Farmland Preservation Program is accepting new applications for farm owners wishing to permanently preserve their land. The State Agriculture Development Committee (SADC), the agency that administers the program, is accepting new applications through its State Acquisition Program in which landowners coordinate directly with the SADC office to preserve their farms.
If you are interested in exploring preservation, the SADC acquisition regional coordinators are ready to help.

Vegetable IPM Update 6/23/21
Sweet Corn
European corn borer (ECB) moth catches remain very low, and concentrated primarily in Gloucester County (see map below at right). Most active infestations now are in pre-tassel stage corn, with whorl corn largely free of feeding as egg laying has declined. Feeding in scouted pre-tassel stage sweet corn ranges to above 30% in Hunterdon County.
Look for the characteristic “shot-hole” type of feeding (photo below at right) and consider treating when infested plants exceed 12% in a 50 plant sample. As plantings proceed to the pre-tassel stage, ECB larvae may be found in emerging tassels (see photo at left). It is a good idea to treat individual plantings as they move into the full tassel/first silk stage one time. This eliminates any ECB larvae that have emerged with the tassels as they begin to move down the stalk to re-enter near developing ears.
Useful insecticides for this particular application include synthetic 
pyrethroids (IRAC Grp 3), spinosyns (including OMRI approved Entrust) IRAC Grp 5), and diamides such as Coragen or Vantacor (IRAC Grp 28) or materials such as Besiege which include the active ingredient in Coragen. Synthetic pyrethroids alone should NOT be used for corn earworm (CEW) protection on silking corn. Control with these materials is very inconsistent.
The highest nightly trap catches of ECB for the week ending 6/23/21 are as follows:
| Downer 2 | New Egypt 1 |
| Cinnaminson 1 | Old Bridge 1 |
| Medford 1 | South Branch 1 |
