Diseases. Scab, brown rot, bacterial spot.
Insects. Oriental fruit moth, leafrollers, lesser peachtree borer, mites, plant bugs, scales.
Bacterial spot. See shuck split schedule for control. Apply at 10- to 14-day intervals.
Mites. For mite control, use see Miticide Recommendations for Peaches.
Early season lesser peachtree borer. If there is only a moderate problem (less than 2 borers/tree), wait until late summer to apply controls (see Postharvest Disorders of Peaches). If there are more than two borers per tree, make an application now and again in late summer. This borer attacks weak or injured trees in winter damaged orchards and diseased trees, especially those with canker. Adult borers deposit eggs in wounds from May through August. The peak egg-laying period for the first generation is in June. Low-volume sprays are not effective on lesser peachtree borer. Use only high-volume, handgun applications. Be sure to cover trunk and scaffold limbs.
