abstract
In present scenario the rapid increase in population and demand of food materials has initiated the large use of pesticides. An ecofriendly alternative to chemical pesticides is biopesticides, which encompasses a broad array of microbial agents, 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 namely, biochemical, plant-incorporated protectants, and microbial pesticides.
