Pesticide use in Potato Next

Potato tuber moth Spray quinalphos 2 ml/litre to manage foliar damage caused by the larvae of the pest. Walls of godown should be sprayed with 0.1% malathion 50 EC (2ml/litre in 500 litre of water) at an interval of three months. Treat potato tubers kept for seed purpose with malathion 5% 1.25g/kg to prevent tuber moth incidence during storage. Treated potatoes should not be used for consumption. EndPrevious Next

Cut worm Spraying of potato foliage, ridges and collar region during evening hours with chlorpyriphos 20 EC 2 ml/litre. Spray chlorpyriphos20 1ml/litre on 4th day after transplanting of potato seedlings raised from TPS (True Potato Seeds) to protect the seedlings from cut worms. EndPrevious Next

Aphid Apply carbofuran 25-30kg/ha or phorate kg/ ha nearer to the base of the seedlings when soil is moist. Spray imidacloprid 0.5 ml/litre or thiamethoxam g/litre of water. Spraying should be given only when cupping and curling of the leaves on the top 1/3 rd portion of the plant and aphids all over the plant are seen. EndPrevious Next

Whitefly Spray methyl demeton 1ml/litre in 500 in 500 litre of water/ha in the early stage. Spray quinalphos 25 3ml/litre in 600 litre of water, phosalone 35 3ml/litre in 800 litre of water in the early and mid stages of the crop. The use of synthetic pyrethroids to control whitefly should be discouraged. EndPrevious Next

Leaf Hopper Spray oxydemeton methyl 25EC (750ml) or dimethoate 30EC (625ml) or acetamiprid 20SP (50 g) in 250 litre of water. Incorporate carbofuran 30-35kg/ha or phorate kg/ha nearer to the base of the seedlings when soil is moist. Spray imidacloprid 200SL (0.5 ml/litre) or thiomethoxam 25WG ( g/litre) in case of severe infestation. EndPrevious Next

Mite Spray dicofol ml/ litre or phosalone 35 EC 2 ml / litre or wettable sulphur 50 6 gm / lit of water. Epilachna beetle: Apply malathion ml/ litre or 0.5ml/ litre of water. Wireworms Apply soil insecticides like mocap kg/ha or nemathroin 30 kg/ha against wireworms Treatment of seed tubers with imidacloprid 200 3ml/kg of seed can also reduce wire worm infestation.
