摘要： 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.

摘要： The present disclosure relates to a plant disease control composition comprising a culture broth of Streptomyces sp. JCK-6141 strain or an extract of the culture broth of the strain, a preparation method therefor and a plant disease control method. The culture broth of the strain or an extract thereof exhibits extremely excellent antimicrobial activity when applied to a causative pathogen of plant disease and thus may be effectively used for plant disease control.
