Thyronectria canker (fungus) |
Cankers develop on trunk and branches. Cankers become elongated and sunken with ridges of callus tissue. When branches are girdled, foliage beyond this point will wilt, turn yellow and die. The fungus is most damaging on drought-stressed trees. |
See the PDC Fact Sheet "Twig Blights and Cankers". Maintain tree vigor by deep watering during periods of moisture stress. |
