The objectives are to find out resistant rice varieties against rice blast disease caused by Pyricularia oryzae and to evaluate the effectiveness of different fungicides to control rice blast disease. A total of seven isolates of P. oryzae were collected from Nay Pyi Taw Union Territory and Ayeyarwaddy Region, and studied for pathogenicity. The isolate, Po1, from Nay Pyi Taw Union Territory was more virulent than all other isolates. In the evaluation of resistance of 33 local rice varieties and 32 YAU rice lines to rice blast disease with Randomized Complete Block design consisting 3 replications, 4 varieties were found to be moderately susceptible and 27 varieties susceptible. The rest two varieties, Shwe Thwe Yin and Naung Ta Moe Se, were observed to be highly susceptible. Of 32 tested YAU rice lines, 13 were found as moderately susceptible, and 18 as susceptible ones. One line, YAU-1211-22-2-1 was highly susceptible. Among tested varieties and lines, 5 varieties namely Manaw Thu Kha, Paw San Hmwe, Ayar Padae Thar, Bu Toyl and Lone Phyu, and 16 lines were found to have quantitative resistance to rice blast disease. In the evaluation of eight fungicides on the mycelial growth of P. oryzae under Completely Randomized design with 4 replications, the IC50 values of Isoprothiolane, Thiophanate methyl, Carbendazim, Mancozeb, Kasugamycin and Tricyclazole were 2.03 ppm, 3.47 ppm, 3.56 ppm, 105.76 ppm, 125.49 ppm and 126.91 ppm, respectively, and they were not significantly different with each other but were significantly lower compared to Dicarboximide (557.95 ppm) and Copper oxychloride (3384.60 ppm). In the evaluation of effectiveness of eight fungicides at minimum inhibition concentrations under Randomized Complete Block design with 4 replications in vivo, all fungicides tested were not different on the percent disease index of rice blast disease. Tricyclazole gave minimum AUDPC value and was significantly lower compared to other fungicides tested. Tricyclazole, Mancozeb, Kasugamycin, Dicarboximide and Carbendazim treated plants were significantly lower infection rate compared to the rest fungicides treated plants. Reduction percent in plant height of Tricyclazole treated plants was 27.7 % and was significantly lesser than plants treated with the rest fungicides except plants treated with Mancozeb and Carbendazim. This study showed the potential contribution of Tricyclazole fungicide for reducing rice blast disease."}]}, "item_1583103108160": {"attribute_name": "Keywords", "attribute_value_mlt": [{"interim": "rice "}, {"interim": " Pyricularia oryzae"}, {"interim": " "}, {"interim": " fungicides"}, {"interim": " rice blast"}]}, "item_1583103120197": {"attribute_name": "Files", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_access", "date": [{"dateType": "Available", "dateValue": "2020-05-05"}], "displaytype": "preview", "filename": "Ye Min Thu, Thesis (PTY- 96).pdf", "filesize": [{"value": "1981 Kb"}], "format": "application/pdf", "licensetype": "license_free", "mimetype": "application/pdf"}]}, "item_1583103131163": {"attribute_name": "Journal articles", "attribute_value_mlt": [{"subitem_journal_title": "Yezin Agricultural University"}]}, "item_1583103147082": {"attribute_name": "Conference papaers", "attribute_value_mlt": [{}]}, "item_1583103211336": {"attribute_name": "Books/reports/chapters", "attribute_value_mlt": [{}]}, "item_1583103233624": {"attribute_name": "Thesis/dissertations", "attribute_value_mlt": [{"subitem_supervisor(s)": []}]}, "item_1583105942107": {"attribute_name": "Authors", "attribute_value_mlt": [{"subitem_authors": [{"subitem_authors_fullname": "Thu, Ye Min"}]}]}, "item_1583108359239": {"attribute_name": "Upload Type", "attribute_name_i18n": "Upload Type", "attribute_value": "Publication"}, "item_1583108428133": {"attribute_name": "Publication type", "attribute_name_i18n": "Publication type", "attribute_value": "Thesis"}, "item_1583159729339": {"attribute_name": "Publication date", "attribute_name_i18n": "Publication date", "attribute_value": "2019-09"}, "item_1583159847033": {"attribute_name": "Identifier", "attribute_value": "https://yauor-yau.archive.knowledgearc.net/handle/123456789/193"}, "item_title": "Screening of rice varieties against Pyricularia oryzae and effect of different fungicides on rice blast disease", "item_type_id": "20", "owner": "1", "path": ["1582963567848/1582969177975"], "permalink_uri": "http://hdl.handle.net/20.500.12678/0000000244", "pubdate": {"attribute_name": "Deposited date", "attribute_value": "2020-03-05"}, "publish_date": "2020-03-05", "publish_status": "0", "recid": "244", "relation": {}, "relation_version_is_last": true, "title": ["Screening of rice varieties against Pyricularia oryzae and effect of different fungicides on rice blast disease"], "weko_shared_id": -1}
