Disease management
Curing: If season is mild the bulb after harvesting is left in the field for curing which makes it firm and dry, where as in hot weather the bulbs are removed to the shade for curing. It takes generally 6-8 days. Bulbs should be saved from rains and direct sunlight. Injured, rotten, diseased and thick-necked bulbs should be sorted out at the time of curing before storage.
