Branch wilt—a destructive fungus disease of English walnuts in California—may be reduced by relatively simple changes in cultural practices. These changes involve: 1, removing all diseased branches from the tree each year; 2, fertilizing soil with a nitrogenous fertilizer; and 3, providing adequate soil moisture by irrigation throughout the growing season.
