Plants may be attacked at any stage; young plants can suddenly dry up or older plants might develop a pale green color accompanied by wilting of lower leaves. Infected plants first develop a dull green color, eventually wilt and turn straw-color. Symptoms often appear on one section of the plant. This is typically followed by broad wilting and the death of the entire plant. Plants may wilt in the middle of the day when the temperature is high in the early stages of infection and appear to recover at night. Some plants may not display symptoms of infection until they reach flowering, at which point they collapse. When the stem is severed, the vascular tissues may develop a brown tint or streaking.
