  • water logging condition.
  • light drizzles with a temperature of 20-250C favours the disease development.
  • Young plants are highly susceptible.


Spread and Survival:

  • Survive: soil, plant debris and graminaceous collateral hosts (Sorghum bicolor, Sorghum halapense, etc). The oospores survive in the soil as well as in the infected plant debris.
