Biological Pathogen Control from AgraQuest protects against many plant diseases, including black spot, powdery mildew, rust, gray mold, leaf blight and scab. Apply alone or in alternating spray programs with other fungicides. Generally most effective when regular spraying begins early in the season before diseases take hold.

Apply Serenade Garden Disease Control to roses, vegetables, fruits, flowering plants, trees and shrubs at 2-4 oz/gal water.
I had bacterial spot on my peach tree and used this. It controlled the spot and kept it from spreading. I had to apply it for 3 weeks which wasn't a problem, it is a biological control after all.Review by Stephanie (on 10/15/13)
