Branch Canker Disease

The primary means of managing avocado branch canker disease is applying chemical treatment to any open wounds to prevent Botryosphaeriaceae spores from entering and initiating infection.

A California avocado tree canker that occurs on twigs, branches or trunks is caused by a complex of fungal pathogens which include many species in the Botryosphaeriaceae family. Canker pathogens can enter and initiate infection through wounds on the bark surface, such as pruning, frost damage and mechanical injury wounds.
