通过室内毒力测定，结果表明：40％氟硅唑乳油、10％苯醚甲环唑水分散粒剂、25％丙环唑乳油和12?5％戊唑醇可湿性粉剂对病原菌菌丝生长具有较好抑菌作用。田间试验结果表明：40％氟硅唑乳油2000倍液和10％苯醚甲环唑水分散粒剂4500倍液防治效果较好，防效分别为65?98％和61?68％。
通過室內毒力測定，結果錶明：40％氟硅唑乳油、10％苯醚甲環唑水分散粒劑、25％丙環唑乳油和12?5％戊唑醇可濕性粉劑對病原菌菌絲生長具有較好抑菌作用。田間試驗結果錶明：40％氟硅唑乳油2000倍液和10％苯醚甲環唑水分散粒劑4500倍液防治效果較好，防效分彆為65?98％和61?68％。

Toxicities of 10 fungicides to C.gloeosporioides were tested by the method of mycelium growth rate.The reG sults showed that the toxicities of 40% Flusilazole EC,10% Difenoconazole WG,25% Propiconazole EC and 12.5% TeG bucomazole WP,their EC50 values are from 0.101 1 mg/L to 0.301 4 mg/L,were higher than the other fungicides.Good fungicides were selected to control C.gloeosporioides in field Camellia oleifera.The results showed that 40% Flusilazole EC using 1∶2 000 and 10% Difenoconazole WG using 1∶4 500 had better effects and their control effecacies were 6 5?9 8% and 6 1?6 8% respectively.
