As we reach the end of July, more fields started to ripen for both muscadines and vinifera grapes, and although  Grape berry moth is a key pest during this time, it continues to be present in low numbers  in our western sites, Rowan Co. and Wilkes Co.

Graphocephala versuta  is present in very low numbers at this time, and a similar situation occurred with the glassy winged sharpshooter.
