Canker - bacterial


This is a fungal problem affecting stem and leaves of the Prunus species most obvious on Plum, Cherry, other stone fruit trees and ornamental (flowering) cherry.  Areas of the tree bark  flatten and sink inwards.  Clear amber-coloured resin ooze may appear, closely associated with the injured bark.  Buds at the tips of affected branches may fail to open, leaves may appear but wither later and the branch may dieback.   Product Solution: Use Fruit and Vegetable Disease Control, and Arbrex Seal And Heal after pruning.
