Biopesticides: Introduction and its prospects

Plant and pest coexist on this planet from the ages. Chemical pesticides are generally used to reduce the damage caused by the pest. As chemical pesticides are costly and hamful for ecosystem, biopesticides are gaining importance. Biopesticides are cost effective and ecofriendly. In India, biopesticides covers 3 per cent of total pesticide production. Biopesticides usage in India rose 23 per cent from 2010-11 to 2016-17 while chemical pesticides only 2 per cent. Biopesticides are mainly microbial origin (Trichoderma sp, Bacillus sp), plant origin (Neem based pesticides) and biochemical compounds (pheromones, repellants, attractants). Many pests like Helicoverpa armigera, Spodoptera litura, Diamond back moth, Fusarium sp are successfully controlled by biopesticides like Trichogramma, Bt, NPV and Trichoderma sp. respectively. Exploration of new source of biopesticdes, formulation and is required. Public private partnership and large investment is required in this sector. | Int.J.Curr.Microbiol.App.Sci 2019 8 2 2960-2964 EXCELLENT PUBLISHERS International Journal of Current Microbiology and Applied Sciences ISSN 2319-7706 Volume 8 Number 02 2019 Journal homepage http www.ijcmas.com Review Article https doi.org 10.20546 ijcmas.2019.802.345 Biopesticides Introduction and its Prospects Nishant Prakash1 Bibha Kumari1 and Shipra Karn2 1Krishi Vigyan Kendra Lodipur Farm Arwal Bihar India Darwin School of Business Guwahati Assam India Corresponding author ABSTRACT Keywords Biopesticides Trichoderma spp. Trichogramma spp Neem Bacillus thringenesis Article Info Accepted 20 January 2019 Available Online 10 February 2019 Plant and pest coexist on this planet from the ages.

Introduction Agriculture has been on this planet from time immemorial and so the plant and pests. Pests cause substantial yield loss in agriculture by damaging plant. Recently chemical pesticides are used to protect the crop from this damage. These chemical pesticides found to be highly effective in killing these pests. Now a day farmers are indiscriminately using these chemical .
