In India about 68% of the total population depends upon agriculture for their livelihood. To guard the agricultural production from the pests, a variety of chemical pesticides are in use. Most of them are toxic. They kill the target pest but also harm the ecosystem seriously by killing a variety of desirable organisms. Most of these pesticides are non biodegradable. It is clear that once used, chemical pesticides exists somewhere causing serious harm to mankind and the ecosystem. Realization of the negative effect of the chemical pesticides the uses of biopesticides is being encouraged all over the world. In present studies it has been observed that biopesticides such as NEEM is capable of destroying only the target pest without harming other desirable organisms or without disturbing the ecological balance. Biopesticides are completely biodegradable. It has been also observed that soyabean grown by using organic farming and neem based pesticide have better quality i.e. better percentage of protein content and negligible pesticide residue. Also the yield has been found to be marginally better in the crop grown by organic farming method using neem pesticide. Thus bio pesticides and organic fertilizers represent some of the most significant crop protection tools that a grower has, to produce a quality crop without sacrificing on the yield.
