Due to the toxic effects of chemical pesticide and other agro chemicals on human beings and livestock, residual toxicity, environmental problems, pest out-breaks and drastic effects on beneficial insects the use chemical pesticide and other agro chemicals are getting reduced /being banned globally. But Biopesticides that are extracted, for example, from neem seed can tackle these problems to make it more eco-friendly, economically viable and socially acceptable for the farmers.
Biopesticides are certain types of pesticides derived from such natural materials as animals, plants, bacteria, and certain minerals. The key insecticidal ingredient found in the neem tree is azadirachtin, the potent insect and mite killer, anti-feedant, and growth retardant isolated from the kernel of neem seeds. The general objective of this research is to produce biopesticide from neem tree seed by the method of solvent extraction. The neem seeds were crushed in to 0.25-0.5 mm sizes for easy grinding. Sample drying was carried out in sunlight for 24hr to obtain easily crushable material. The maximum particle sizes of the ground mixed sample were 0.5 mm. The effects of particle size, solvent, temperature and time on the yield were investigated. The optimum results were obtained at 0.25mm particle size, 69oC temperature and with yield of 41.78% at the time of four hour. Under these condition hundred percent of water soluble and stable biopesticide was obtained by mixing with the neem oil and liquid detergent. Investigation on the technical and economic feasibility of the work for biopesticide production was performed and results from the feasibility study indicated that the proposed work was feasible with rate of return (RR) 31% and with the payback period of estimated to be 3 years.
