The distinctive underground symptoms of club root have 
earned it the nickname "fingers and toes". These symptoms 
consist of swellings on the roots and occasionally on below 
ground stems. Swellings range from small round enlarged 
areas to large spindle-shaped galls. All or part of the 
root system may be affected. In cases of mild infection no 
above ground symptoms may be evident. In severe cases, 
nutrient absorption and water uptake are disrupted and 
above ground symptoms are those commonly associated with 
nutrient deficiencies and drought stress. Plants may show 
varying degrees of yellowing (chlorosis). Infected plants 
may also wilt during the hot part of the day. Flagging, 
wilting of uppermost leaves is common on young infected 
plants. Premature death, stunting and reduced size and 
quality of heads are also symptoms associated with club 
root.
