Godronia Canker

Overview

Godronia cassandrae ( Fusicoccum putrefaciens).

Damage

Small (2-7cm), reddish brown, oval-shaped lesions develop on one-year-old stems, usually at the base of a bud. Older infections girdle stems and die, and the leaves turn reddish-brown, mostly attached to the stem e, giving a “flagging” appearance. Lesions may take 1-3 years to fully girdle and kill individual branches

Disease cycle

This fungus over- winters on canker lesions on stems. Spores are released from young canker lesions during cool, wet weather in the spring but mostly in the fall and cause new infections. Godronia Factsheet English Godronia Factsheet Punjabi
