著者らは、ジャガイモ青枯病菌に対する抗菌成分を含有する雑草であるアメリカフウロの利用方法を検討した結果、アメリカフウロ乾燥物のうね内土壌混和処理と太陽熱土壌消毒を組み合わせることにより、高い防除効果が得られることを見出した。そこで、本技術がトマト青枯病でも有効であるか否かを検討した結果、本処理を行った試験区においては、植え付け8ヶ月後でも青枯病の発生が確認されなかった。以上の結果から、アメリカフウロは各種園芸作物の青枯病防除に有効な生物防除素材であると考えられた。, In a previous study, we found that a 70% aqueous ethanol extract of fresh aerial tissue of G. carolinianum L. showed antimicrobial activity against the pathogen causing bacterial wilt of potato. Furthermore, we demonstrated that a treatment combining the soil incorporation of dried aerial tissue of G. carolinianum into the soil and solarization was highly effective in the control of bacterial wilt of potato. Therefore, we have examined the control effect of the above-mentioned treatment against bacterial wilt of tomato in a field trial. The development of this disease did not observe though eight months had passed since tomato seedlings was planted. These findings suggest that G. carolinianum could be used as a biological agent for the control of bacterial wilt of various crops.
