Necrotic Leaf Blotch (Golden Leaf Drop)

Symptoms

Irregular necrotic blotches occur on mature leaves within 12 to 24 hours. The shape of the necrotic area is restricted by larger veins, which are not affected. Blotches may vary in number from one to six or more per leaf. Affected leaves generally turn yellow and drop within 4 to 7 days of symptom development. Leaf symptoms and defoliation occur in two to four waves during the growing season. Young, vigorously growing trees are less affected than older, slower growing trees.
