PESTICIDAL COMPOSITIONS CONTAINING AZADIRACHTIN AND AT LEAST 50 ALCOHOL OR OTHER APROTIC SOLVENT, WITH LESS THAN 15 WATER; METHODS OF EXTRACTION FROM NEEM SEEDS

摘要

Storage stable pesticide compositions comprising neem seed extracts which contain azadirachtin as the active pesticidal ingredient wherein the compositions are characterized by their non-degrading solvent systems and high concentrations, i.e., greater than 10 g/l, of azadirachtin. In one embodiment, the pesticide compositions contain solvent systems characterized as having greater than 50% by volume aprotic solvents and less than 15% by volume water. In a second embodiment, the pesticide compositions contain solvent systems characterized as having greater than 50% by volume alcohol and less than 5% by volume water.
