Grape Pest Survey – 4th Week of June

— Written By and last updated by

As the grapes grow, we again started to catch grape berry moth in one of our Northwest locations (Wilkes Co.), although at low numbers. Captures were zero in the rest of locations.

Glassy-winged sharpshooter, continues to be present in the same locations as last week, Currituck, Perquimans and New Hanover Counties at higher numbers.

Also, the leafhopper Graphocephala  versuta, continues to increase its numbers, particularly at locations where no pesticide application are made.
