Since the disease was first reported in 1902 in Java, it has spread over tropical and subtropical countries growing bananas. In Okinawa, it was found in 1961. Because of the disease spreads so rapidly, banana growers have feeling anxiety. The causal fungus infects from the stomata of the lower surface of the first to fifth leaves from the top. The incubation period of the disease is four to eight weeks, and the visible symptoms appear in the lower leaves than the fourth to fifth from the top. According to the author's study, the disease in Okinawa seems to be the same disease as reported from other countries. The causal fungus of the disease in Okinawa is identified to Mycosphaerella musicola by studying imperfect and perfect stages of it. Although the imperfect stage appears in summer and fall, the perfect stage is found in fall only. The control of the disease has to be carried out synthetically by the following methods: 1) Planting varieties resistant to the disease, 2) Growing bananas in the place protected against wind, 3) Removing the disease infected leaves from banana plants, and 4) Spraying fungicides. History of application of fungicides could be classified into three steps as follows: 1) Boldeaux mixture or other fungicides containing copper was sprayed, 2) Oil or copper-oil mixture was applyed, and 3) New kind of fungicides such as Manebdithane was started to use. The control of the disease may become successful by the use of development and use of new fungicides in the future. It is recommendable to spray the fungicides two or three weeks intervals during summer and fall.","subitem_description_type":"Other"},{"subitem_description":"論文","subitem_description_type":"Other"}]},"item_1617186643794":{"attribute_name":"Publisher","attribute_value_mlt":[{"subitem_1522300295150":"ja","subitem_1522300316516":"沖縄農業研究会"},{"subitem_1522300295150":"en","subitem_1522300316516":"Okinawa Agriculture Research Society"}]},"item_1617186702042":{"attribute_name":"Language","attribute_value_mlt":[{"subitem_1551255818386":"jpn"}]},"item_1617186920753":{"attribute_name":"Source Identifier","attribute_value_mlt":[{"subitem_1522646500366":"ISSN","subitem_1522646572813":"1344-1477"},{"subitem_1522646500366":"NCID","subitem_1522646572813":"AN00083297"}]},"item_1617186941041":{"attribute_name":"Source Title","attribute_value_mlt":[{"subitem_1522650068558":"ja","subitem_1522650091861":"沖縄農業"}]},"item_1617187056579":{"attribute_name":"Bibliographic Information","attribute_value_mlt":[{"bibliographicIssueDates":{"bibliographicIssueDate":"1966-12","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"2","bibliographicPageEnd":"34","bibliographicPageStart":"30","bibliographicVolumeNumber":"5"}]},"item_1617258105262":{"attribute_name":"Resource Type","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_1617265215918":{"attribute_name":"Version Type","attribute_value_mlt":[{"subitem_1522305645492":"VoR","subitem_1600292170262":"http://purl.org/coar/version/c_970fb48d4fbd8a85"}]},"item_1617605131499":{"attribute_name":"File","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","filename":"158.pdf","mimetype":"application/pdf","url":{"objectType":"fulltext","url":"https://u-ryukyu.repo.nii.ac.jp/record/2015204/files/158.pdf"},"version_id":"2bfb2ac7-3b46-47b0-8f19-a7866fe2db52"}]},"item_title":"バナナ斑葉病に関する基礎研究","item_type_id":"15","owner":"1","path":["1642838312941","1642838412624"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2009-01-29"},"publish_date":"2009-01-29","publish_status":"0","recid":"2015204","relation_version_is_last":true,"title":["バナナ斑葉病に関する基礎研究"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2022-10-31T07:32:21.867552+00:00"}
