Crown and Cane Gall
Agrobacterium tumefaciens
14 host plants
Crown and cane gall produces swollen, knobby growths at the soil line and on canes. You see rough, tumor-like enlargements that can girdle and kill plants. The bacterium causes this problem on many hosts. Remove infected plants to prevent spreading to healthy stock.
Use certified nursery stock from fields where gall has not been found. Inspect planting stock and do not plant new canes that show galls on canes, crowns, or roots.
