Detection and prevention of yellow spots in onion crop

Yellow Spot: Almost round spots form on the seeded stems, on which purple-colored owls form and later appear brown. The crop looks scorched, and the sticks are broken.

Prevention: For the prevention of these diseases, treat the seeds with thiram or captan medicine (3 grams per kg of seeds). If symptoms of the disease appear, 600 grams of Indophil M-45 and 220 ml should be taken. Dissolve triton or linseed oil in 200 liters of water and spray it on the crop per acre. After this, spray three sides at an interval of 10 days.
