Detail:

Take 1 kg. Of dried cow dung in an earthern pot and mix it with 15 gm. of tobacco. Fume this mixture keeping the earthern pot below the vegetable canopy; the smoke is enough to kill the harmful pests. The procedure is to be repeated every week. For treatment of insects and pests affecting grams (choli), grind 25 gm. of tobacco, dilute with water and keep overnight. In the morning, mix it with a little coconut oil and soap solution and sprinkle on the leaves of the choli Normally, five to six feet pandals are made for vegetables (from the family of creepers); this makes it easy for creepers to grow and for the vegetables to be picked. For vegetables like bittergourd (karela) and kuluru she suggests fuming instead of insecticidal sprays: Take 1 kg. of dried cow dung in an earthern pot and mix it with 15 gm. of tobacco.

"Tobacco and its evil cousin nicotine are good as a pesticide" -

PAS 2:

"Gardeners have been using soap to control insects since the early 1800s. During the first half of the 19th century, whale oil soap and, more commonly, fish oil soaps were an important part of insect control. Recent tests indicate Ivory liquid dishwashing detergent, diluted with water to a 1 to 2% solution, provides the most consistent control and is easy to mix. There are also soaps available that are specifically formulated to control insects on plants. Thorough coverage of the plant and repeated applications may be necessary to bring insect populations under control. High rates of soaps and detergents may damage some varieties of plants. The most effective soaps have carbon chains of C-12 or C-18. Laurate (C-12) is the main component of most dishwashing liquids and various other products in common usage. The richest natural source of this is coconut oil."

PAS 3:

"Pest control measures include application of synthetic pesticides (Decis, Curacron, Darmabas, Thiodan, Furadan, Rekor, Furacron), sulfur, lime, soap and kitchen ashes. These are all somewhat effective in reducing pest numbers. Infestations are too heavy for hand picking/cleaning." -
