  • Hydrophic extracted neem oil-a novel insecticide
    Patent number: 5411736
    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.
    Type: Grant
    Filed: July 9, 1993
    Date of Patent: May 2, 1995
    Assignee: W. R. Grace & Co.-Conn.
    Inventors: James C. Locke, James F. Walter, Hiram G. Larew, III

  • Insecticidal compositions derived from neem oil and neem wax fractions
    Patent number: 5372817
    Abstract: Novel insecticide compositions prepared from neem seeds are disclosed. Two distinct neem derived insecticides 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.

  • Hydrophobic extracted neem oil-a novel fungicide use
    Patent number: 5368856
    Abstract: 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.
    Type: Grant
