烯肟菌胺·戊唑醇对桃树褐斑穿孔病的防治效果研究

Control Efficacy of Enoxime-tebuconazole Suspension Coating Agent Against Cercospora circumscissa

试验比较了20%烯肟菌胺·戊唑醇悬浮剂和80%代森锰锌可湿性粉剂不同用量对桃树褐斑穿孔病的防治效果。结果表明:20%烯肟菌胺·戊唑醇悬浮剂0.6 mL/kg、1 mL/kg对田间桃树褐斑穿孔病的防治效果分别为81.25%和83.31%,显著高于80%代森锰锌1 mL/kg药剂处理,且对桃树生长无药害,可在桃产业中推广使用。

The control efficacy of different dosage of 20%Enoxime-tebuconazole suspension coating agent and 80%Mancozeb wettable powder agent against Cercospora circumscissa was tested and compared in the study.The results indicated that 20%Enoxime-tebuconazole suspension coating agent 0.6 mL/kg and 1 mL/kg had significantly better control efficacy(81.25%and 83.31%,respectively)against C.ircumscissa than that of 80%Mancozeb wettable powder agent(71.73%).And moreover,the Enoxime-tebuconazole agent had no phyto-toxicity to peach crops,suggesting that it could be used in the peach production.
