This study's objective was to evaluate the contributions of benomyl and a melanin biosynthesis dehydratase inhibitor (MBI-D) mixture to preventing the re-emergence of MBI-D-resistant in rice fields. In nursery boxes, applications of diclocymet or mixtures of diclocymet and tiadinil showed low leaf blast incidences, but MBI-D-resistant isolates were re-selected. However, a management program applying both benomyl and MBI-D-related products to nursery box plants prevented the re-emergence of MBI-D-resistant isolates more effectively than the application of only MBI-D-related products.
本研究的目的是评估苯菌灵与一种黑色素生物合成脱水酶抑制剂（MBI-D）的混合物对防止稻田中MBI-D抗性菌再次出现的作用。在育苗箱中，使用双氯氰菌胺或双氯氰菌胺与噻唑锌的混合物，叶瘟发病率较低，但仍再次筛选出了MBI-D抗性分离株。然而，对育苗箱植株同时施用苯菌灵和与MBI-D相关的产品的管理方案，比仅施用与MBI-D相关的产品能更有效地防止MBI-D抗性分离株的再次出现。
