| 摘 要： | 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％。

| Abstract: | Toxicities of 10 fungicides to C.gloeosporioides were tested by the method of mycelium growth rate.The results showed that the toxicities of 40% Flusilazole EC,10% Difenoconazole WG,25% Propiconazole EC and 12.5% Tebucomazole 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 65.98% and 61.68% respectively. |
