What is Bio-pesticide?
» An aspect of Biological control that uses natural enemies such as pathogens, parasitoids and/or predators to manage insect and mite pest populations.
» Biopesticides may be derived from animals (e.g. nematodes), plants (Chrysanthemum, Azadirachta) or micro-organisms (e.g. Pseudomonas, Trichoderma, nucleopolyhedrosis virus), and include living organisms (natural enemies) etc.
» Biopesticide is a formulation made from naturally occurring substances that controls pests by nontoxic mechanisms in an ecofriendly manner.
» Refers to any living microorganism such as bacteria, fungi, nematodes, viruses, protozoa, parasitoids and predators that controls pests by biological non-toxic means.
» Microbial pesticides are composed of microscopic living organisms (viruses, bacteria, fungi, protozoa, or nematodes) or toxin produced by these organisms.
» Microbial pesticides includes insecticides, fungicides, herbicides and growth regulators of microbial origin.
Benefits and Advantages
» Increase crop yield by 20-30%.
» Inherently less toxic than conventional pesticides.
» Affect only the target pest and closely related organisms.
» Effective in very small quantities and often decompose quickly.
» Crop yields remain high.
» Cheap, renewable and can be handled safely.
» Difficult for insects to develop resistance to these pesticides.
