How do I control grain mould in rabi jowar and protect grain colour?

Grain mould discolours and weakens jowar grain when rain and humidity hit during grain filling and maturity, lowering both food quality and price, and it is a bigger problem in rainy spells. Reduce it by growing mould tolerant varieties with the right maturity so the crop ripens after the wet period, avoiding very late or off-season flowering into rains, and harvesting promptly once mature rather than leaving heads exposed to dew and rain. After harvest, thresh and dry the grain quickly to a safe low moisture so mould does not develop in storage. White-grained food types are more affected in appearance, so for rabi maldandi jowar that fetches a premium for bold white grain, timely harvest and good drying are key. Confirm tolerant variety choice with your local KVK.
