Roots may be decayed. The bark at base of branches may die and slough off. Before growth starts in spring, remove and destroy all leaves on ground and lodged in twig crotches. Prune out dead twigs and severely cankered branches as soon as noticed. Spray with a fungicide just after removing dead leaves and branches and as new leaves begin to develop.
Many leaves drop early.
Young twigs may die. Begin spraying with a foliar fungicide as new leaves emerge. Plants are weakened, stunted and lack vigor, may wilt on hot days and recover at night. Leaves may be pale green to bronze or orange. Plants gradually decline and branches may die back.
