We are suggesting to cherry owners a supplemental program to target the Cherry Bark Tortrix. And extra Fall and Spring Kaolin Clay spray of the truck plus a parasitic wasp release. The clay creates a residue barrier that prevents insects from entering the tree.
The parasitic wasp is applied during our supplemental visits. We hand a card with wasp eggs near your tree. The card is black and the size of an address label, which makes it hard to see. They hatch within days and start looking for food, which is the Cherry Bark Tortrix.
We have been targeting cherry trees with deep root feeding, too boost the tree's general health and help to combat the pests.
