Charcoal Rot
Causal Agent: (fungus - Macrophomina phaseolina)
A water-soaked lesion develops around the crown of the plant, followed by the appearance of an amber-colored ooze at the surface. This area becomes dark brown, dried and cracked. Small black fungal structures (microsclerotia) are then formed in this area. A dark ring is visible beneath the outer layer when a cross section is cut through the canker. Infected plants have yellow crown leaves and die soon after symptoms are observed.
