  • Composition for controlling nematode comprising grammicin compound as effective ingredient and uses thereof
    Patent number: 11000039
    Abstract: A method for controlling nematode includes treating a plant or soil with a composition comprising a grammicin compound of Formula 1 or an agriculturally acceptable salt thereof. The grammicin compound may be isolated from a Xylaria grammica strain so that it is harmless to a human body, does not cause any environmental contamination, and exhibits an excellent control activity against root knot nematodes. Thus, it can be advantageously used for developing an environment-friendly natural nematicide and production of a high value-added organic agricultural product.
    Type: Grant
    Filed: September 27, 2017
    Date of Patent: May 11, 2021

  • EL 000614 strain having nematicidal activity against root knot nematode and uses thereof
    Patent number: 10980242
    Abstract: Xylaria grammica EL 000614 strain has a nematicidal activity against root knot nematode. A method for controlling root knot nematode includes treating a crop, a crop seed, or a field for cultivation with a nematicidal microorganism formulation. The method has very little possibility of having a problem related to environmental contamination, and exhibits a high mortality and activity of inhibiting egg hatching for sweet potato root knot nematode (M. incognita). It is expected that the strain can be very advantageously used as an innovative biological control agent which enables prevention of problems associated with environmental contamination.
