Stone Fruit Disease Control Toolbox - Fungicide and Antibiotic Efficacy

Fungicides should be selected based on stone fruit diseases to be controlled and product efficacy for each. Growers can prevent resistance to fungicides by alternating chemicals by FRAC code group.

Stone Fruit Diseases and Recommended Fungicides

Recommendations are based on chemical registrations as of December 2017.

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 (see pages 205-206 in the 2018-2019 Penn State Tree Fruit Production Guide).

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

Degree of control: 1 = best, 2 = good, 3 = fair, 4 = slight, 5 = none, 6 = no registration

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.
c. Rankings assume no resistance to the active ingredient of the bactericide or fungicide in the pathogen population in your orchard.
d. Effectiveness on stone fruit diseases are recommended to tank-mix the product with captan.
e. In 2018, Flint Extra will replace Gem 500.
