Crown Gall
Identification
Galls can appear on roots, trunks or branches of infected trees and shrubs. They are raised, tumor-like growths. Galls commonly form at the base ("crown") of the plant, where the stem/trunk meets the soil.
Damage prevention
The most effective preventative measure is to plant species that are less prone to getting crown gall in the first place. There is not much you can do once an established plant is infected. While a gall will not usually harm the mature plant, it can potentially spread the disease to younger plants in the area.
Physical control
If a gall appears on a newly planted tree or shrub: dig it up, if possible, along with the soil in its immediate vicinity. Destroy the plant, and refill the area with new, clean soil. Another option is to prune and destroy infected branches. Be sure to sterilize all tools used in this process once you are done.
Chemical control
Chemicals are rarely used to prevent or control crown gall.
