Raspberry anthracnose, caused by the fungus Elsinoe veneta, is the most common and widespread disease of brambles. The disease is most destructive on black and purple raspberries. Although red raspberries, blackberries, dewberries, and loganberries are commonly affected, anthracnose is not usually as serious on these brambles. The disease infects the canes, leaves, fruit, and stems of berry clusters. Losses result from defoliation, a general stunting and decrease in cane vigor, a reduction in fruit yield and quality, and the death of the canes. Infected canes are more susceptible to winter injury and other diseases than healthy canes.
