Western Gall Rust


Description of Disease

Western gall rust forms globose to fusiform galls form on the branches or trunk of infected trees. On large trees this results in a hip-canker. The fungus produces powdery yellow-orange spores on surface of the galls or cankers from May-July. Trees are stunted and younger trees may be killed if the gall is formed on the main stem.
