Description

Cankers are dead sections of bark on branches or main trunks of trees. Bark may be killed by mechanical damage or by plant pathogens, especially fungi and bacteria. Most plant pathogens are unable to penetrate bark directly but will quickly colonise wounded tissue.
Cankers varies with the host plant or tree. Apples, pears and Cherries are often affected. The bark of the plant may be raised and split with oozing from the canker. It may enlarge to ring a branch which eventually die.
