Outline of Final Research Achievements |
Detailed mechanisms of anaerobic soil disinfestation with diluted ethanol (Et-ASD) were investigated on physicochemical and biological factors such as organic matter content, water-soluble organic matter fraction, soil microorganisms, etc. by comparing some reduction-promoting soils with non-reduction-promoting soils under several temperature conditions. Especially, for Et-ASD treatment under low temperature conditions, the factors were confirmed whether these exerted density-reducing effects of soil borne pathogens in vitro between two soil types. It was proved that identified factors were applied to non-reduction-promoting soils to enhance ASD efficiency even under the low temperature condition.

Academic Significance and Societal Importance of the Research Achievements |
土壌還元消毒効果は、特に低温下で効果が不安定になる欠点があった。この要因が明らかになり、この物理化学的、生物的要因を土壌還元消毒効果が不安定な土壌に付与する事によって、土壌還元消毒効果が改善した。すなわち、幅広い作物の土壌伝染性病原微生物に対して、冷涼な地域や低温期でも安定した土壌還元消毒効果が発揮できることで、低濃度エタノールを用いた土壌還元消毒は世界中で利用可能な革新的な汎用技術となり得ることが実証できた。
