Front 8

Symptoms of bacterial canker and blast (Pseudomonas syringae)

Back 8

In spring, limb dieback with rough cankers. Cankers are irregularly shaped, brown, water-soaked areas that develop in the bark and outer sapwood of spurs, branches, and the tree trunk. Small cankers on twigs @base of infected buds. Amber-colored gum may exude from the margins. In cold, wet weather, blossoms may turn brown, shrivel, and cling to the tree. Leaves also may develop dark spots that later drop out. Sunken spots may develop on young fruit. A more severe form of the disease, the sour sap phase, generally occurs in younger trees. This phase may not show gum and cankers, but the inner bark is brown, fermented, and sour smelling. Reddish flecks and pockets of bacterial invasion in bark occur outside canker margins. Trees frequently sucker from near ground level.

Front 9

Solutions for bacterial canker and blast (Pseudomonas syringae)

Back 9

Avoid planting on shallow soils. Plant less susceptible rootstocks. Choice of rootstock and varieties can influence the susceptibility of plums, prunes, and cherries to bacterial canker and blast. Generally, vigorous trees have less trouble with bacterial canker. Practice measures such as adequate fertilizer and irrigation that encourage good plant growth. If trees have been infected, remove entire affected branches in the summer, being sure to eliminate the entire canker and a few inches below. If freezing conditions occur during bloom or early fruit growth, cover them or use protective shelters.
