For the control of this insect and its larvae, Hamirbhai Parmar creates a small, spicy but elaborate fire, the smoke of which rids the vegetable plants of insects. He lights the fire by gathering dry grass and bark of coconut (Cocos nucifera) early in the morning (4-5 a.m.). In the fire, he puts twigs of black mustard, swallow wart and neem tree as well as husks of garlic, onion and fenugreek. This traditional practice kills the insects if it is carried out four times in as many days. Farmers from generation to generation have been using this technique.
Ingredients: Dry grass, coconut (Cocos nucifera) fibres, black mustard (Brassica campestris) twigs, neem (Azadirachta indica) tree, husks of garlic, onion, fenugreek
