Ergot: Claviceps fusiformis
Symptom
- Cream to pink mucilaginous droplets of "honeydew" ooze out of infected florets on pearl millet panicles.
- Within 10 to 15 days, the droplets dry and harden, and dark brown to black sclerotia develop in place of seeds on the panicle.
- Sclerotia are larger than seed and irregularly shaped, and generally get mixed with the grain during threshing
- Conditions favoring the disease are relative humidity greater than 80%, and 20 to 30 0C temperatures during flowering.
Management
- Spray any one of the fungicides like Carbendazim 500g or Mancozeb 1000g /ha when 5 - 10% flowers have opened and again at 50% flowering stage
