Blossoms and young leaves wilt, decay, and turn brown early in the bloom period. In humid conditions, gray spores may appear on the infected flower parts. Extensive twig dieback often occurs. Cankers sometimes develop on the twigs and branches. A sticky substance may ooze out of them. Small, circular brown spots appear on the young cherries, and may enlarge to rot the fruit. Sometimes, the rotten fruit is covered with gray spores.
Treat the tree with a fungicide that''s labeled for brown rot, following label directions. Remove and destroy all infected and dried-up fruit. Prune out cankers and blighted twigs. Clean up and destroy all debris around the tree.
