Shot Hole Symptoms on Peach
Shot
Hole (fungus - Wilsonomyces carpophilus): Was formerly called Coryneum
blight. Blight lesions on leaves are small, circular, purple spots. In advanced
stages spots on the leaves fall out giving the leaf a ragged appearance. Defoliation
seldom occurs unless infection is severe. Fruit infection is rare. Buds and twigs
die if heavily infected. For most effective disease control, apply dormant sprays
immediately after leaves are shed or just prior to budbreak in spring. See
fungicides.
