摘　　要：为筛选出安全高效的柑橘沙皮病防治药剂,对新型复配剂40%吡唑萘菌胺·戊唑醇悬浮剂在柑橘沙皮病防治中的效果及其适宜使用剂量进行探讨。通过2021—2022年的田间药效试验发现40%吡唑萘菌胺·戊唑醇悬浮剂对柑橘沙皮病具有较好的防治效果。2021年施药处理3次后,40%吡唑萘菌胺·戊唑醇悬浮剂200 mg/kg对柑橘叶片和果实沙皮病的防治效果分别为79.60%和77.97%,2022年施药处理3次后,40%吡唑萘菌胺·戊唑醇悬浮剂200 mg/kg对柑橘叶片和果实沙皮病的防治效果分别为81.65%和76.37%,防治效果显著优于对照药剂20%吡唑萘菌胺可湿性粉剂和430 g/L戊唑醇悬浮剂。40%吡唑萘菌胺·戊唑醇悬浮剂对柑橘安全、高效,值得应用于柑橘沙皮病防治的示范与推广。The study aims to screen the safe and efficient fungicide for controlling citrus melanose,clarify the control effect and the appropriate dosage of the new compound isopyrazam·tebuconazole 40%SC on citrus melanose.Field efficacy tests of the new compound isopyrazam·tebuconazole 40%SC for controlling citrus melanose were carried out for two consecutive years from 2021 to 2022.The results of the two years experiments showed that isopyrazam·tebuconazole 40%SC 200 mg/kg had a good control effect on citrus melanose.After three times of application in 2021,the control effect of isopyrazam·tebuconazole 40%SC 200 mg/kg on citrus leaves citrus melanose and fruits citrus melanose were 79.60%and 77.97%,respectively.After three times of application in 2022,the control effect of isopyrazam·tebuconazole 40%SC 200 mg/kg on citrus leaves citrus melanose and fruits citrus melanose were 81.65%and 76.37%,respectively,which were significantly better than 20%isopyrazam wettable powder and 430 g/L tebuconazole suspension.The isopyrazam·tebuconazole 40%SC is safe and efficient for the prevention and treatment of citrus,which is worthy of application in the demonstration and promotion of citrus melanose control.
