Measures to control Charcoal Rot disease in Soybean Crop

Charcoal rot disease is a fungal disease that affects a wide range of plants, including soybeans, corn, sorghum, potatoes, and beans. It is caused by the soil borne fungus Macrophomina phaseolina. The fungus survives in the soil and in plant debris for long periods of time.

Environmental favorable factors for pests/Diseases:

• Temperature: Favorable temperatures for charcoal rot development are in the range of 25°C to 35°C.
• Humidity: Low humidity levels, coupled with high temperatures, exacerbate charcoal rot disease in soybeans.

• Wilting of leaves, especially during hot weather
• Drying and death of older leaves
• Yellowing of leaves
• Stunted growth
• Dark brown or black lesions on stems and roots
• Formation of small, black fungal structures (microsclerotia) on infected tissue.
