My matar gets a white powdery coating late in the season. Want to know sowing time and how to stop the disease.

Field peas are sown in the rabi window, generally from late October into November in north India, and early timely sowing helps the crop finish before powdery mildew pressure peaks in warmer late-season weather. Powdery mildew shows as a white powdery coating on leaves and pods and spreads fast in dry, mild conditions, so grow resistant varieties, avoid very late sowing, and spray a recommended fungicide or wettable sulphur at the first sign, following the label and pre-harvest interval. Good spacing and airflow reduce build-up. Confirm sowing dates and variety with your KVK.
I sow my peas a bit early now and the powdery mildew comes much later, after most pods are already set. Late sowing was my problem before.
Scout closely from the warmer late-season days, because once that white coating spreads across the canopy it is very hard to pull back. I spray at the very first patches I see on the lower leaves and it stays manageable. Waiting even a week too long made it explode on me once.
