不同杀菌剂对油茶炭疽病田间防治试验

Fungicidal Control of Colletotrichum gloeosporioides in Field Camellia oleifera

摘要:

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2 000倍液和10%苯醚甲环唑水分散粒剂4 500倍液防治效果较好，防效分别为65.98%和61.68%。

Abstract:

Abstracts: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 EC50values are from 0.101 1mg/L to 0.301 4mg/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.
