Root rot disease, also known as stem rot or charcoal rot, is one of the most destructive diseases affecting sesame crops. It is caused by a soil-borne fungus called Macrophomina phaseolina. This fungus can survive in the soil for extended periods, forming structures called sclerotia that allow it to persist through harsh conditions.

Scientific name: Macrophomina phaseolina

Type: Fungal Disease

Target: Root

Damage: Dark brown lesions at the collar region

Environmental favorable factors for pests/Diseases:

Temperature: Many root rot fungi are heat-loving. Soil temperatures between 25C and 30C can promote rapid growth of these pathogens.

Humidity: Fungal pathogens that cause root rot thrive in moist environments. Overwatering or poorly drained soils can create ideal conditions for these pathogens to grow and infect sesame roots.
