Neem oil fatty acid distillation residue based pesticide

Neem oil fatty acid distillation residue based pesticide which is storage stable, water soluble, environmentally safe and rich in bitter principles. It is obtained by saponifying the neem oil fatty acid distillation residue with an aqueous alkali, drying the resulting soap, allowing the resulting soap cake to cool down to room temperature, pulverising the soap cake, fortifying the resulting fines by mixing with a small quantity of neem oil, allowing the fines to dry at room temperature and if desired, forming an aqueous emulsion by mixing the pesticidal fines with water at room temperature. The fines may be enriched by mixing with a small quantity of a solvent extract of neem tree parts prior to allowing the fines to dry.
