Stone Fruit Diseases and Recommended Fungicides

Recommendations are based on chemical registrations as of August 2015.

To avoid fungicide resistance, practice good cultural control methods, use fungicide mixtures, tank-mix with a broad-spectrum protectant, and alternate chemicals by FRAC code group.

Please refer to product labels and the Penn State Extension Tree Fruit Production Guidefor details on chemical use.

a. Uppercase names are trade names; lowercase names are common names for products with more than one trade name.
b. No efficacy data from Pennsylvania; expected performance based on the ai chemistry and preliminary observations in neighboring states.
