Spotted Lantern Fly nymphs have taken over.
Yes, you can use Bonide Fruit Tree Spray Concentrate on grapes up to 7 days before harvest. We are not sure if this product will help control spotted lantern flies since this is a new invasive pest and this product is not labeled to control it.. Please take a few moments to review this article from your Penn State Extension to find out if you need to report finding this pest to your local Extension office. We recommend consulting them for best treatment practives.
