Biology, epidemiolgy and management of the pathogenic fungus Macrophomina phaseolina (Tassi) Goid with special reference to
charcoal rot of soybean (Glycine max (L.) Merrill).
M.phaseolina (Tassi) Goid causes a
charcoal rot. The fungus infects the root and lower stem of 500 plant species (Smith and Wyllie, 1999).
is a serious pathogen of
charcoal rot disease in the maize plant recently in Punjab, Pakistan.
Assistant Director Information Naveed Asmat Kohloon here Wednesday told that
Charcoal Rot disease was attacking at inner portion of trunk.
Infection was determined visually by the presence of
charcoal rot lesions on root tissue and by laboratory culture of root sections.
The new lines were also selected for resistance to diseases such as sudden death syndrome, stem canker, and frogeye leaf spot, with moderate resistance to
charcoal rot. They both belong to Maturity Group V, which makes them well adapted to production in the Mid-South.
Charcoal rot [caused by Macrophomina phaseolina (Tassi) Goidanich] incidence is much higher when the plants are exposed to prolonged drought and high temperature stress during grain development (Edmunds, 1964).
Control of
charcoal rot fungus Macrophomina phaseolina by extracts of Datura metel.
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.
