Nectria twig blight
Disease
Nectria twig blight
Nectria cinnabarina (Tode:Fr.) Fr.
Distribution: Occurs from eastern US and Canada, west to Michigan.
Typically, small cankers can be found girdling the base of cluster buds that bore fruit the previous year. This leads to the wilting and dying of leaves and twigs of current season's growth (A). Bright pink to orange fruiting bodies appear at the nodes (B) or on developed cankers or pruning stubs during wet weather in early summer (C).
