Fusicoccum canker - Phomopsis amygdali (Del.) Tuset & Portilla
IPM scouting in stone fruits > fusicoccum canker
Fusicoccum canker is found primarily on peach in the mid-Atlantic and southeastern states. Infected twigs wilt and die because of elongate, brown, sunken cankers, often with a target pattern, at their bases (see bottom photo). Twigs are blighted from girdling and from the action of a toxin secreted by the fungus.
