Neem Pesticide Facts
- As early as 1930, neem cake was applied to rice and sugarcane fields against stem borers and white ants.
- Some innovative farmers in Karnataka and Tamil Nadu states in India even today "puddle" green twigs and neem leaves in rice nursery beds to produce improving various methods like crop rotation, sanitation, deep plowing, soil solarization, mixed cropping, and the improving the quality of neem seeds.
- It has been reported that by using 0.1 to 0.2% neem emulsions there was a significant bio-effectiveness shown against the sugarcane aphid, Melanaphis saccdhari; corn aphid, Rhopalosiphum maidis; the blue butterfly, Euchrysops chejus on green gram and cowpea; Bihar hairy caterpillar, Spilosoma obliqua gram pod borer, Helicoverpa armigera on chickpea and pigeon pea. robust seedling and simultaneously ward-off attack by early pests-leafhoppers, plant hoppers, and whorl maggots.
- Neem is quite effective against armyworm, one of the most devastating pests of food crops in the western hemisphere. Azadirachtin in extremely low concentrations – a mere 10 mg per hectare – inhibits these pests.
- Med fly, one of the most damaging horticulture pests, can be controlled by spraying neem solution under fruit trees.
- Neem products are quite effective against the larvae of a number of mosquito species which stop feeding and die after treatment. At present developing countries use expensive imported chemical pesticides to control mosquito population. These countries can save a lot of money by using simple neem products which are very effective.
- Neem extract is useful against leaf miner, a serious pest in parts of North America. Neem seed extracts work as well as available commercial synthetic pesticides. It has been approved by the US Environmental Protection Agency for use on leaf miners.
- Neem in extremely useful as an anti-feedent and ovipositional repellent for protection of crops like tobacco, groundnut, cotton and sweet potato from the damages caused by tobacco caterpillar or tobacco cutworm, a serious polyphagous pest.
- Experiments have shown that neem is also effective against fruit flies. Whereas the conventional pesticides kill fruit flies as well as their internal parasites, neem products on the other hand, leave the biological-control organisms unaffected; and only kill fruit flies. This reduces eliminates adverse, unintended effects.
- Neem is useful against gypsy moth, a pest which is causing severe damage to forests in parts of North America. Laboratory tests have shown that a very low concentration application of neem seed extract formulation, approved by the US Environmental Protection Agency, can kill gypsy moths.
- Neem is the most important organic pesticide among all bio-pesticides for controlling pests and nematodes. This pesticide does not leave any residue on the crop like other chemical pesticides and therefore, is the preferred organic pesticide of choice.
