Nematodes, plants (e.g. Chrysanthemum, Azadiracthaindica), microbes (e.g. Bacillus thuringiensis, Tricoderma, Nucleopolyhedrosis virus) which are the parental material of biopesticides Three major classes of biopesticides o Microbial Biopesticides o Plant incorporated Biopesticides o Biochemical Biopesticides Table 1: summarized 3 types of biopesticides Microbial biopesticides Plant incorporated biopesticides Bio-chemical biopesticides Products which consist of microorganisms as active ingredients. Mainly utilized fungi, bacteria and virus. Ex. Bacillus thurinngiensis Here, genes inserted into the plant tissue and pesticides produce inside its own. Ex. Bt canola, Bt cotton, Bt potato etc. Naturally occurring substance that control pests by non-toxic mechanisms. Ex. Azadiractin from Neem tree.
