Pritam Chattopadhyay. Sukanta K. View. Sukanta Kumar Sen. Serratia entomophila, a Gram negative non spore forming bacteria, is commercially exploited as biocontrol agent of pasture pest, grass grub (Costelytra zealandica, Coleoptera) in New Zealand as soil inoculants. Incorporation of commercial chitosan based formulation LS254 and LS255, comprising of P. macerans and Bacillus subtilis into soil at the ratio of 1:40 (Formulation:Soil) increased plant biomass and yield (Vasudevan et a. 2002). The bacterial strain S. entomophila AB2, used in this study, was originally isolated from epizootic Heliothis armigera larvae (Chattopadhyay et a. 2011). As majority of them persist for longer period of time and are carcinogenic in nature, their disposal is a matter of global concern (Jain et al.

As for conventional pesticides, formulation of biopesticides comprises the blending of a biologically active metabolite or microorganism with a carrier or solvent as well as adjuvants, to develop a product which can be delivered to the target weed, pathogen or pest using existing equipment. The objectives of biopesticide formulation are to stabilize the active metabolite or microorganism, to optimize delivery to the target, to protect the biopesticide during storage and in the field, and to enhance the efficacy of the biopesticide.

Are existing formulation technologies suitable for biopesticides? .

Are existing formulation technologies suitable for biopesticides? A lack of formulation technologies specifically designed to meet the special needs of biopesticide products is often cited as one of the factors hindering their wider usage. For biopesticides to truly become mainstream global products, active ingredients must be developed along with formulations that provide attributes specific for the biopesticide industry, explains Mr Donaldson. The acquisition of AgraQuest gave us a strong position in bacterial-based biologics, while the acquisition of Prophyta means we have a strong platform for fungal-based biologics, Bayer says.

Biopesticides, a contraction of 'biological pesticides', include several types of pest management intervention: through predatory, parasitic, or chemical relationships. The term has been associated historically with – and by implication – the manipulation of living organisms. Regulatory positions can be influenced by public perceptions, thus: in the EU, biopesticides have been defined as "a form of pesticide based on micro-organisms or natural products".

Pests resistency against most of the chemical pesticides and Bt based products are of global concern. Insect epizootics provide a good natural source of entomopathogens. Serratia entomophila is a Gram negative non spore former bacteria known for its application against Newziland grass grub. The strain S. entomophila AB2, isolated from dead pod borer in India, is not only shows its biopesticide activity against lepidopteron pests, also found to be a plant growth promoter through solubilizing inorganic phosphate and zinc and producing IAA. Therefore, it may be a very good biocontrolling agent in IPM practice. For any non spore-former, product formulation is a crucial step. A vermiculite based prototype formulation shows to enhance crop yield about 250% and reduce pest attack about 50% in ground nut and sesame when applied to field through soil conditioning method only. Single strain with multidimensional attributes will definitely pave a new way to direct the biopesticides research in coming decade. The strains will also provide novel insecticidal genes that may have used in future pest management with the aids of genetic and/or protein engineering.
