Bio-pesticides are referred as pesticides derived from natural resources like animals, plants, bacteria and certain minerals. Among types, biochemical pesticides, microbial pesticides and plant-incorporated-protectants normally influence only the target pest and closely related organisms, in contrast to broad spectrum. The inappropriate and excessive use of modern agricultural pesticides has a major effect on the environment resulting in contamination of soils, health issues to human beings, flora and fauna, household animals and wild life making these synthetic chemicals environmentally intolerable. Bio-pesticides have several advantages over synthetic; most importantly they are cost effective and ecofriendly. The total world production of biopesticides is over 3000 tonne/year, which is increasing at a rapid rate. India has a vast potential for bio-pesticides. In India, bio-pesticides cover 3% of total pesticide production. Recently biopesticides usage in India raised 23% while chemical pesticides only 2%. The market share of bio-pesticides is only 2.5% of the total pesticide market. An updated representation of the current knowledge on microbial bio-pesticides and of the availability of active substances that can be used in integrated pest management programs in agro ecosystems is described in this chapter. |
