Abstract

A novel fungicide 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 fungicides exhibit the ability to control various fungi.
