The white powder appears on the leaves and other green parts, which later become light-colored white spots. These spots gradually increase in size and become spherical, covering the lower surface as well.
In severe infection, the foliage turns yellow causing premature leaf loss.
Disease infected plants undergo early maturation resulting in heavy yield loss.
When the initial disease appears, spray twice a day with NSKE or neem oil 75 ml per 15 liters of water.
Spray Hexaconazole 5% SC 400 ml or Thiophanate methyl 70% WP or Azoxystrobin 23 SC 200 ml per acre in 200 water at an interval of fifteen days.
