Bacterial cancer of fruit trees – it primarily attacks stone trees. On the shoots, branches, the branches and trunks there are necroses and cankers, leading to sudden or chronic tree dieback. Dieback is accompanied by abundant gumming. Sometimes flowers die and fruit sets rot. In less infected trees, cut out dead shoots, branches or limbs (cutting wounds are smeared with Funaben 3), and in the case of a strong infestation in the forks of the limbs or the trunk, the uprooting and burning of the whole tree remains.
