Biopesticides have been developed as environment friendly alternate to chemical pesticides. Pesticidal properties of neem leaves have been known in literature. A novel biopesticide using whole neem fruit in combination with other ayurvedic herbs in micro fine dust form has been developed. The formulation particles create a sustained release effect since the ingredients are gradually released and thus a long term protection from insects is achieved. The product is economical and efficient in the field.
Proposed technology is process for manufacture of a biopesticide formulation based on whole Neem fruit with additives and Ayurvedic herbs in a microfine powder form. Extracted active ingredient Azadirectin, is unstable and sensitive to moisture, pH and light losing activity under field conditions. This technology overcomes these problems and offers an efficient and economic alternate.
This biopesticide describes a novel technique of making micro size powder of whole neem fruit and other Ayurvedic herbs. Azadirectin, active ingredient of neem, becomes unstable after extraction and when sprayed on the crop, its anti insecticidal effect becomes short lived. Therefore, this technology utilizes Azadirectin in its original form as in neem fruit without extraction. Since azadirechtin is unstable in solution form, presently available neem based bio pesticides are less efficient and need frequent spraying adding to the cost. Considering this aspect a bio pesticide formulation using whole neem fruit (without extracting oil) in a micro fine powder form (20 micron) has been developed. This has solved the problem of instability of Azadirechtin and cost of extracting of oils is also eliminated.
Use of whole neem fruit and other ayurvedic herbs in micro fine dust form as pest controller is the novelty of this biopesticide.
Azadirachtin is the key ingredient of neem-based biopesticide responsible for the inhibition of pests. Three major factors that influence instability of Azadirachtin after extraction, are degradation in water, pH sensitivity and photo degradation. In this process, whole neem fruits are used in its original form without extracting Azadirachtin separately. This method ensures better Azadirachtin stability as well as effective utilization of other limonoids in neem fruits. The whole neem fruits are dried and ground with inert material into fine powder using a special technique. This method reduces particle size and creates new surface area, which in turn increases the availability of Azadirachtin on the surface of the particles. This whole neem powder based microfine formulation is found to be more effective than the equivalent products available in the market.
