The most important stalk rotting organisms, however, are Macrophomina phaseolina (Tassi) Goidanich, the causal organism of charcoal rot, and a number of Fusarium species, the pathogens responsible for Fusarium stalk rot (Edmunds and Zummo, 1975; Bramel-Cox et al., 1988; Wildermutch et al., 1997).
phaseolina also causes charcoal rot in many crops; for example in legumes it is responsible for progressive wilting followed by defoliation that results in vigor and yield reduction (Meyer et al.
