Grape:
Grape Berry Moth (GBM): The timing for second generation treatments in Gloucester County and surrounding areas will be on 6/21 to 6/22. Grape berry moth is the most common insect in NJ vineyards that will directly damage the fruit (See Figure 1.) This timing is for the use of Intrepid, Altacor, and Delegate. If you are using other products like Danitol, Baythroid, Brigade, or Imidan, then you can make the application a few days later. This timing is calculated for 810 degree days (base 47) after wild grape bloom, which was May 16.
