An eco-friendly alternative to chemical pesticides is biopesticides, which encompasses a broad array of microbial pesticides, bio-chemicals 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. Main aspects of botanical pesticides, search and exploitation of new botanicals as pesticides including isolation, identification and evaluation of the active components and another use of botanicals in agriculture in different forms like direct spray applications of various plant materials, soil amendments for different plant parts, intercropping of biologically active plants with main crop, use of botanical based synthetic pesticidal formulations and also use of botanicals as synergists/ binders for synthetic pesticides.
