Detail:

The powder form of 1 kg of tobacco (Nicotiana tabacum) and soak it in 3 L water in an earthen pot for three days. Filter this decoction and add 500 ml of neem (Azadiachta indica) oil. Mix this with soap. Dilute the mixture with water and spray it on the cotton crop. The results of a better flowering and fruit formation and reduced flower dropping, are apparent within a week.

PAS 1:

Put a thin layer, about 1 1/2 centimetres, of fresh neem leaves in the bottom of whatever container you use to store grain. On top of that put in a layer of sun dried grain about 30 centimetres thick. Then put in another thin layer of neem, and on top of that another 30 centimetres of grain. Keep on alternating a thin layer of neem leaves with a thicker layer of grain up to the top of the container. Then close it up. Your grain will be safe from insects. [Neem Protects Stored Grain, G. Venkataramani, Agricultural Correspondent, The Hindu, Kasturi Buildings, Anna Salai, Madras ‑ 600 002, INDIA.]

PAS 2:

Neem (Azadirachta indica) has been demonstrated to reduce insect populations in stored products through its toxic and growth-disrupting and other effects on the pests. Grain movement and percussion also help to kill pests in grain. The combination of neem

PAS 3:

"Their antiparasitic activity was evaluated in bioassays against adult fleas (Ctenocephalides felis), blowfly (Lucilia cuprina) larvae, nematodes (Caenorhabditis elegans), and ticks (Rhipicephalus sanguineus) larvae and adults, (Lxodes ricinus nymphs). None of the extracts killed fleas and blowfly larvae effectively at the concentrations tested. Only N. tabacum K326 and N. glutinosa exhibited moderate anthelmintic activity. All extracts significantly repelled R. sanguineus ticks, but not I. ricinus, and the nicotine-rich extracts rapidly knocked down all tick species and stages at high concentrations. The link between nicotine and tick knockdown was confirmed by successfully testing the pure alkaloid at concentrations found in the tobacco extracts. In contrast, repellent activity could not be correlated to the individually tested alkaloids (nicotine, nornicotine, anabasine, anatabine), although anatabine and nornicotine were active in the tick bioassay at high concentrations.
