[Prospect of biopesticide on organic farming]

Phil Trans R Soc B. Plant secondary metabolites as an alternative in pest management.

Hiopesticides is an ecological phenomenon whereby secondary metabolites synthesised by plants and microorganisms too influence biological and agricultural systems; they may be either stimulatory or inhibitory. To a large extent, agriculture development has been due to the use of synthetic pesticides to reduce the losses caused by pests.

Grainge M, Ahmed S. Successful manipulation of pest behaviour could provide protection of the resource crop plant through the use of stimuli that either enhance or inhibit a particular behaviour and ultimately change its expression 34, General aspects and approaches to the study of plant secondary metabolites from the pest management perspective A characteristic feature of plants and other sessile organisms, which cannot run away in case of danger and do not have an immune system to combat pathogens, is their capacity to synthesize an enormous variety of low molecular weight compounds, the so-called secondary metabolites 7.

Only a hiopesticides percentage of plants has been screened for pesticidal activity, and in addition, many such studies are not complete and often bioassay procedures used have been inadequate or inappropriate 20, Natural products that have been used commercially as crop protection agents.

These bioassay techniques, with exception of perhaps a few, cannot be used as a rapid, general screening procedure for biopesitcides detection of toxic secondary metabolites biopesticices of cost, specificity, sophistication or objection by animal rights activists.

Standardisation of complex mixtures of plant materials is a challenge because plants are subject to natural variation figure 3.

Background and present situation of the development and use of plant metabolites in pest management In the early days, cultivational controls such as rotational farming, selection of resistant crops, and physical controls were used for crop protection.

Combining reduced-risk products, trap crops and yellow sticky traps for greenhouse whitefly Trialeurodes vaporariorum management on sweet peppers Capsicum annum. At the same time, some of bbiopesticides products have affected human health and have created environmental and pest-resistance problems 2. They include allomones emitting species benefitskairomones receptor species benefits and ee both species benefit. WOA1 Safeners are provided which reduce the toxicity of biocide-containing pesticide formulations on microbial inoculants.

Preliminary studies for the evaluation of extracts and pure compounds extracted.

Types and Applications – IJAPBC ; Biopesticides are very effective in the agricultural pest control without causing serious harm to ecological chain or worsening environmental pollution. A polymer composition comprising an antimicrobial material for inhibiting the growth of microorganisms in close proximity to said polymer composition.

WOA1 The present invention relates to the use of an extract of knots from trees belonging to the genus Pinus for the treatment of a pathogenic infection due to at least one oomycete.

Recent technological improvements in the area of chromatographic separation methods have nevertheless provided new possibilities to accelerate the overall process of bioassay-guided fractionation. An ecofriendly approach for pest control Suman Gupta and A. The standardisation of natural product-based anti-insect preparations has really the biggest constraint and has subsequently been hindered their potential marketability compared with conventional pesticides The ecological impacts of secondary metabolites extend beyond plant-insect coevolution.
