Title:
CONTROL OF DISEASE INJURY DEVELOPED IN RICE PLANT NURSERY BED BY TREATING RICE PLANT SEED WITH MICROORGANISM
Document Type and Number:
Japanese Patent JP3209565
Kind Code:
B2
Abstract:
PURPOSE: To suppress or control the development of plural disease injuries occurring in a rice plant nursery bed without using a chemical agrochemical by directly inoculating a specific bacterium having antagonistic action on many pathogenic microbes into a rice plant seed.
CONSTITUTION: A rice plant seed is treated with a bacterium of the genus Pseudomonas having antagonistic action on pathogenic microbes of disease injuries developed in a rice plant nursery bed, especially the bacterium of the species Pseudomonas cepacia, among them, new Pseudomonas cepacia AGF-158 strain (FERM P-3834) to suppress and control the disease injuries developing in the rice plant nursery bed. For example, bakanae disease, damping-off, blast, bacterial damping-off and bacterial brown stripe of the rice plant are cited as the disease injuries developing in the rice plant nursery bed. The Pseudomonas cepacia AGF-158 strain is capable of manifesting strong antagonistic action on plant pathogenic molds and plant pathogenic bacteria. The economic burden on farmers cultivating the rice plant is reduced and many operations following the disinfection of the rice plant seed with a germicide can be omitted by this method for controlling which is effective even against resistant microbes.
