Grape Pest Survey- 4th Week of August

— Written By and last updated by

Two of our locations have completed harvest, and we have concluded our monitoring efforts. We will continue to visit these vineyards every other weeks to observe plants for evidence of the invasive spotted lanternfly, until October.

Grape berry moth and glassy winged sharpshooter were not caught in any of our locations. Graphocephala versuta counts keep declining, and almost none were caught this week.
