The present investigation was carried out in order to utilize this phenomenon in controlling diseases caused by zoospores of this fungus. Two of polyethylene glycol dodecyl ether, with HLB (hydrophile-lipophile balance) of 11 and 13,were very effective on bursting of zoospores at a low concentration of 12.5μg/ml. Polyethylene glycol nonilphenyl ethers, with HLB of 10.9,12.0 and 13.1 were effective at 25μg/ml. Tested surfactants with HLB over 13 or under 10 generally gave poor results. Moreover, two sorbitan-type surfactants, Tween-21 and -81 failed to show the desired effect. Cucumber seedlings grown in culture solution and inoculated with zoospores escaped invasion when added 25 to 50μg/ml of polyethylene glycol nonilphenyl ether, [chemical formula]. It was noted that the seedlings were severely injured to wilt with 100μg/ml of the surfactant. Though there are not a few problems to be solved before the method is put into practice, the investigation is being continued in a hope that it is applied as one of the effective disease-protection methods in water culture of crops where a comfortable environment is provided for zoospores of plant pathogenic fungi, such as Phytophthora and Pythium.","subitem_description_language":"en","subitem_description_type":"Other"}]},"item_3_source_id_1":{"attribute_name":"雑誌書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AN00062275","subitem_source_identifier_type":"NCID"}]},"item_3_source_id_20":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"00757373","subitem_source_identifier_type":"PISSN"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorAffiliations":[{"affiliationNameIdentifiers":[],"affiliationNames":[{"affiliationName":""}]}],"creatorNames":[{"creatorName":"宮田, 善雄","creatorNameLang":"ja"},{"creatorName":"ミヤタ, ヨシオ","creatorNameLang":"ja-Kana"},{"creatorName":"Miyata, Yoshio","creatorNameLang":"en"}],"familyNames":[{},{},{}],"givenNames":[{},{},{}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"阿部, 宏二","creatorNameLang":"ja"},{"creatorName":"アベ, コウジ","creatorNameLang":"ja-Kana"},{"creatorName":"Abe, Koji","creatorNameLang":"en"}],"familyNames":[{},{},{}],"givenNames":[{},{},{}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"西, 新也","creatorNameLang":"ja"},{"creatorName":"ニシ, シンヤ","creatorNameLang":"ja-Kana"},{"creatorName":"Nishi, Shinya","creatorNameLang":"en"}],"familyNames":[{},{},{}],"givenNames":[{},{},{}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"並木, 隆和","creatorNameLang":"ja"},{"creatorName":"ナミキ, タカカズ","creatorNameLang":"ja-Kana"},{"creatorName":"Namiki, Takakazu","creatorNameLang":"en"}],"familyNames":[{},{},{}],"givenNames":[{},{},{}],"nameIdentifiers":[{}]},{"creatorAffiliations":[{"affiliationNameIdentifiers":[],"affiliationNames":[{"affiliationName":""}]}],"creatorNames":[{"creatorName":"桂, 琦一","creatorNameLang":"ja"},{"creatorName":"カツラ, キイチ","creatorNameLang":"ja-Kana"},{"creatorName":"Katsura, Kiichi","creatorNameLang":"en"}],"familyNames":[{},{},{}],"givenNames":[{},{},{}],"nameIdentifiers":[{}]},{"creatorAffiliations":[{"affiliationNameIdentifiers":[],"affiliationNames":[{"affiliationName":""}]}],"creatorNames":[{"creatorName":"高嶋, 四郎","creatorNameLang":"ja"},{"creatorName":"タカシマ, シロウ","creatorNameLang":"ja-Kana"},{"creatorName":"Takashima, Shiro","creatorNameLang":"en"}],"familyNames":[{},{},{}],"givenNames":[{},{},{}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-02-20"}],"displaytype":"detail","filename":"KJ00000078903.pdf","filesize":[{"value":"1.1 MB"}],"format":"application/pdf","mimetype":"application/pdf","url":{"label":"KJ00000078903.pdf","url":"https://kpu.repo.nii.ac.jp/record/4904/files/KJ00000078903.pdf"},"version_id":"e4b25fde-bb09-4ca8-8973-5b7689adf0ad"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper"}]},"item_title":"非イオン界面活性剤を用いた Phytophthora および Pythium による植物疾病の新しい防除の観点(農学部門)","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"非イオン界面活性剤を用いた Phytophthora および Pythium による植物疾病の新しい防除の観点(農学部門)","subitem_title_language":"ja"}]},"item_type_id":"3","owner":"14","path":["416"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2017-02-20"},"publish_date":"2017-02-20","publish_status":"0","recid":"4904","relation_version_is_last":true,"title":["非イオン界面活性剤を用いた Phytophthora および Pythium による植物疾病の新しい防除の観点(農学部門)"],"weko_creator_id":"14","weko_shared_id":-1},"updated":"2024-04-26T04:28:24.032243+00:00"}
