1 Ratings assume that the fungicide is used at the recommended rate and applied correctly

2 Except in orchards where resistance is present.

3 Resistance or tolerance is suspected in some orchards but has not been proven.

4 Limited residual activity. Rating assumes regular reapplication during periods of heavy disease pressure. More effective against sooty blotch than fly speck.

5 Activity of these materials is highly rate-dependent. Stated efficacies assume a rate of 9 fl.oz/A for Rubigan 1E, 5 oz/A for Nova 40WP, and 6 oz/A for Procure 50WS on MM 106-size trees.

6 Activity of Flint and Sovran are approximately equal when rates of formulated product are compared at a 1:2 Flint/Sovran ratio.
