Grape IPM in the Northeast

Early August

IPM practices to be implemented

 


 

Grape Berry Moth Risk Assessment Protocol

An insecticide should be applied at this time in vineyards determined to be at high risk for grape berry moth (also available as a 234k pdf file). Vineyards in the low- and intermediate-risk categories over the 6 percent threshold for grape berry moth damage during the third week of July scouting should also receive an insecticide application. Vineyards in the low- and intermediate-risk categories that did not exceed the 6 percent damaged cluster threshold require no treatment at this time.
