Novel fungicide compositions prepared from neem seeds are disclosed. Two distinct neem derived fungicides obtained non-polar, hydrophobic solvent neem seed extracts which are substantially free of azadirachtin, by removing the hydrophobic solvent and cooling the resulting neem oil to separate a semi-solid neem wax fraction and a clarified neem oil fraction.

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.

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.

A novel method of controlling fungi is disclosed. The method involves contacting the fungi, or a surface to be protected from the fungi, with a neem oil fungicide derived from a neem seed extract. The neem oil is 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.
