Grape Pest Survey – 1st Week of September

— Written By and last updated by

Harvest keeps going in a full swing, and about half of our locations are completely harvested with the rest to conclude soon. Due to the hurricane, some vineyards in eastern NC finished harvest a bit earlier than anticipated.

We caught one last glassy winged sharpshooter  in our northeast location at Perquimans Co. just before Hurricane Dorian hit. A very few, close to zero, specimens of the Graphocephala leafhopper and the three-cornered alfalfa hopper were caught.
