Cherry leaf spot. This spray program is necessary where leaf spot is active beginning at petal fall and continuing after harvest.

Leaf Spot Recommendations for Sweet Cherries

Lesser peachtree borer (LPTB)/peachtree borer. See Peach Integrated Pest Management Program in this section. For LPTB, apply as a coarse spray to trunk and lower limbs in up to two sprays: June 10-20 and August 10-25. Do not spray fruit; there is a 14-day preharvest interval for Asana XL, a 14-day preharvest interval for permethrin, and a 21-day preharvest interval for Thionex. Young trees: If peachtree borer damage is present, make two applications, the first around July 15 and the second around August 10. Use Thionex 50W (1 lb) or Asana XL (4.0 fl oz) or permethrin 3.2AG (1.6 fl oz) per 100 gallons of water. If using only one application, apply between July 20 and August 1.
