Crown gall can be difficult to manage once established, so prevention and early management are especially important for BC grape growers.  

Cold injury, pruning, and mechanical damage can create opportunities for infection, while infected nursery material can introduce the bacterium into a vineyard before symptoms appear.  

A new research factsheet explains what growers should watch for and explores practical ways to reduce risk, from planting material and equipment sanitation to preventing winter injury, retrunking, and replanting.
