Environmental Impact of Microbial Pesticides uri icon


  • Biological control constitutes an important component of integrated pestmanagement (IPM). However, the non-availability o f efficient biocontrolagents is one of the major constraints in adopting IPM practices. Microbialcontrol, which makes use o f naturally occurring microbes to control insectpests, pathogens, and weeds, is less harmful to nontarget organisms andthe environment than the chemical pesticides. Microbials are promisingalternatives to chemical pesticides and have opened up new vistas in insectpest management to aid promotion o f safe, eco-friendly pest management.The use o f microbial pesticides in pest management is quite limited becauseo f lack of appropriate formulations and the availability of quality productsto the farmers. Since 2006, the registration o f the microbial pesticides forcommercial purposes has been made mandatory in India. It warrantsinformation on toxicological results against mammals and eco-toxicity dataon nontargets such as fishes, birds, earthworms, honeybees, and silkworm.The data is to be generated with technical product and the formulation ofevery strain intended for commercialization. It is also mandatory to generatedata on the safety of the formulation to natural enemies along with data onthe bioefficacy and phytotoxicity to the crop. Fourteen primary microbialpesticide products and their formulations have been registered in India by2009. There are 478 products o f the 14 microbial pesticides registered inIndia. There are 184 products for the management of plant pathogens
