  • Method for producing a nematocidal composition by heat treating a pH-adjusted fermentation broth
    Patent number: 6942860
    Abstract: The present invention is directed to a method for producing a new nematocidal composition particularly useful against plant parasitic nematodes and also a process to prevent damage resulting from nematode infestation. The method for production of the composition involves heating a pH-adjusted fermentation broth of microorganisms to a temperature of at least about 100° C. for at least about 15 minutes. Preferably, the microorganism is Gibberella fujikuroi, Streptomyces erythraeus, Bacillus sphaericus, Bacillus thuringiensis or Fusarium moniliforme.
    Type: Grant
    Filed: February 4, 2003
    Date of Patent: September 13, 2005
    Assignee: Valent BioSciences Corporation
    Inventors: Prem Warrior, Daniel Feulner Heiman, Linda Anne Rehberger, Ronald Eugene Johnson, James Russell Hansen, Kevin Allen McVicker
