| Outline of Final Research Achievements |
Organic acids and microorganisms of lowland soil were analyzed in order to elucidate the mechanism of suppressive effect of rice bran on Monochoria vaginalis in organic rice production. Outdoor experiments could not reveal the mechanism on the assumption of the effect of aromatic carboxylic acids. Therefore, laboratory experimental system simulating the suppressive effect of rice bran was established. The system revealed the essentiality of microorganisms and chemicals produced through the reaction of the microorganisms and rice bran. However, the microorganisms and chemicals could not be identified in the research period.
