Anthracnose Control

dogwood anthracnosePlants such as Dogwoods, Oaks, Maples, Sycamores, and others are prone to this fungal disease. Spraying fungicides on trees and shrubs several times during the time when their new leaves are emerging can reduce the amount of anthracnose that may damage the plant. Anthracnose will cause brown to black spotting and blotches on leaves. This disease will later spread to infect twigs and will begin to start die-back of infected twigs, causing eventual branch loss.
