Q
Do I have borers in my peach trees?
Answer(s)
A
If you see oozing holes at the base of your peach tree including the surface roots, you probably have peachtree (crown) borers. They attack about the first of July each year, and once the borers are inside the tree there is no control.
Recommendation: Spray the lower trunk and exposed root system in early July and again the first week in August with an approved insecticide. Follow label instructions. Organic controls include beneficial nematodes.
