The entire fruit may become semi-watery, decayed, and light brown. Tannish gray spore tufts break through the fruit skin, giving it a powdery appearance. Blossoms suddenly wilt, turn brown, and wither, and later they are covered with a tan-gray mold. Oval or elliptical, brown, sunken cankers form on the fruit spurs, twigs, and small branches. Gum commonly oozes out from the canker margins during wet periods.
Sanitation is critical for disease control.
All dropped and rotted fruit should be promptly picked up and destroyed. Remove all mummies from trees. Prune out all cankers and blighted twigs after the last picking and during the dormant season. Prune trees annually to open the center. Remove and burn or bury all wild and neglected stone fruit trees.
