Abstract
A novel insecticide derived from a neem seed extract comprising neem oil which is substantially free of azadirachtin, said neem oil being prepared by extracting dried, coarsely ground neem seeds with a non-polar, hydrophobic solvent to obtain a neem oil extract, and then removing the solvent to obtain the neem oil. These neem oil insecticides exhibit the ability to repel insects from plant surfaces and kill insect pests at various life stages.
