ABSTRACT
Economic importance The economic importance of Fusarium foot rot is difficult to determine for three reasons. First, the effect of each individual pathogen on yield may vary. Second, naturally occurring
Fusarium foot rot (crown rot, brown foot rot) symptoms are varied. In temperate areas, the most common symptom is a dark brown lesion around the node of mature plants. Long thin dark brown vertical streaks are also frequently observed. In more arid areas, dryland foot rot may develop. The entire stem base becomes girdled with a dark brown lesion (148, 149). Tissue may become soft and white, or pink fungal growth with orange spore masses can develop.
