HOST PLANTS: Common in cabbages, radishes, turnips, canola, and other plants belonging to the mustard family. SYMPTOMS: Diseased roots grow gall formations on latent roots and gives the shape of a club or spindle. Eventually the roots will become dry and cracked due to their inability to absorb moisture. Above ground, outer leaves on infected plants eventually turn yellow or brown. FAVORED ENVIRONMENT: Fungal spores can be spread by wind, water and garden tools. Disease development can occur over a wide range of conditions, but is favored by excessive moisture, low soil pH and soil temperatures between 64 and 77 degrees F. Spores can survive in the soil for as many as 10 years. CLUB ROOT CONTROL: Choose resistant cultivars when possible. Try to prevent the occurrence of this disease by keeping a clean garden and rotating crops. Keep in mind that the disease spores can persist in the soil for many years. If club root is present, you may want to solarize the soil*. Carefully remove infected plants and sterilize garden tools (one part bleach to 4 parts water) after use. Raise your garden soil's pH to a more alkaline 7.2 by mixing oyster shell lime into it in fall. Check soil pH often. |
