Shothole borer: Good sanitation (removing previous season's large wood pruning and wood piles from the orchard or near-by) is the best management tactic. Insecticides are only effective against adults. The second generation flight begins in late July or early August. Yellow sticky traps placed on orchard borders will detect activity of the adult beetles. Spraying the border trees (rows) with recommended products in high water volumes will protect the remainder of the orchard in many situations where external sources are the primary problem.
Powdery mildew: Apply to reduce next season's powdery mildew potential. Apply within 30 days after harvest. Optimum timing is 7 to 10 days after harvest. Full wetting of the foliage is required.
Bacillus thuringiensis subsp. kurstaki: Bts are stomach poisons so complete coverage is very important for control. Two or three applications are usually required.
petroleum oil, summer: Do not spray wet foliage. Do not spray when freezing temperatures are anticipated within 48 hours of an oil application, above 90° F (32° C) or when plants are under heat or moisture stress.
