For growers who don’t have clubroot on their farms, be sure any used or demo’d equipment you buy is clean before you bring it home. Clubroot spreads with the movement of contaminated soil, and the most common way to transfer soil from field to field is on farm machinery and vehicle tires. Clubroot Sanitation Guide
Clean equipment before it leaves the auction site or the farm it comes from. Also check that the transport truck is clean. As a precaution, you may want to pressure wash the equipment again when it gets to your farm. Do this in a commercial truck wash or on the farm in a low-traffic grassed area away from any cultivated soil.
