In groundnut cultivation, the initial symptoms of leaf spot disease appear as small yellow spots on the leaves. Over time, these spots enlarge and turn dark red. In the advanced stages of the disease, these spots merge together, causing the leaves to dry and fall off. To control this disease, mix 200 grams of Carbendazim or 200 grams of Mancozeb with 200 liters of water and spray it on the leaves using a hand sprayer until the leaves are thoroughly wet.
