NEEM , extracts of Azadirachta indica tree, can influence nearly 200 species of insects. It is an insect growth regulator and a feeding deterrent. Neem products work by intervening at several stages of the life of an insect. They may not kill the pest instantly but incapacitate it in several other ways. Use of neem products does not give immediate results like chemical insecticides.
Some patience is required after application.
Insects like flies, cockroaches, leaf miners, mosquitoes, fruit flies, thread worms or nematodes and snails are affected by neem products. Neem products have proved to be remarkably benign to beneficial insects. Derived from the seeds. Mix at the rate of 5 ml. Works best with emulsifier.
