Abstract: Agriculture plays a crucial role in the life of an economy. Agriculture not only provides food and raw material but also employment opportunities to a very large proportion of population. But one of the major issues facing by them is pest. The worldwide consumption of pesticide is about two million tons per year, out of these India shares 3.75%. Indiscriminate uses of these agrochemicals have caused adverse effects on soil health, animal health, water quality and developed problems like insect resistance, genetic variation in plants, toxic residues in food and feed. An ecofriendly alternative to chemical pesticides is biopesticides. Biochemicals derived from micro-organisms and other natural sources, and processes involving the genetic incorporation of DNA into agricultural commodities that confer protection against pest damage. Biopesticides fall into three major classes. Microbial pesticides are composed of naturally occurring Bacteria, fungi and viruses that controls pests by nontoxic mechanism and eco-friendly manner. Biological pest control mechanism fallowed to protect plants from pests and diseases without resorting to the use of chemicals. Creating awareness among the farmers as well as farm workers about hazards of chemical pesticides and encourage them to use Microbial pesticides.
