Treatment of trunks
Treating trunks in mid-May and again in mid-July with carbaryl kills hatching peachtree borer eggs and
adults emerging from pupae before they can lay more eggs. Once newly hatched larvae bore into the tree,
they can't be killed. A pheromone trap is available to detect the presence of peachtree borer adults.
Remove soil, weeds, and suckers from the base of the tree trunk and spray the trunk from the scaffold
crotch to the ground so that some of the spray solution puddles and drenches the area below the soil surface.
