Early blight and late blight are the important fungal diseases. Spraying zineb (2 g/litre) is effective to control early blight. Copper fungicides can control late blight. Cut worms, aphids and jassids are common pests of potato. Dusting with carbaryl 10 % DP immediately after planting can control cut worms. To control aphids and jassids spraying dimethoate (1 ml/litre) is effective.
