Charcoal rot (Macrophomina phaseolina) is a soilborne fungus, which can infect the roots and lower stem of over 500 species of plant.[1]



It causes seed and seedling rots, wilt, root and stem rots, leaf spot, rotting of developing pods and seed, early maturation, chlorosis and incomplete pod filling.[1]


The fungus causes a stalk rot during hot, dry conditions.[1]




Practice a three- or four-year crop rotation. Earlier planting will result in plants growing a larger, shading canopy thus reducing soil temperatures and conditions conducive to the fungus. Avoid overcrowding. Provide sufficient levels of phosphorus and potassium. Maintain moisture, apply a mulch if necessary.[1]
