摘　　要：通过在花椒园定点调查和防治药剂的筛选试验,结果表明,海拔越高花椒膏药病发病程度越重;花椒病株率与树龄呈正相关;膏药病的发生与介壳虫发生呈正相关。室内毒力测定结果表明三唑类药剂对膏药病的毒力高于百菌清等广谱性杀菌剂;田间药效试验表明质量浓度为215 mg/L 43%戊唑醇悬浮剂对花椒膏药病的防效较好,连续2次的防治效果达89.26%,可在生产中推广应用。Through the fixed-point investigation in pepper park and the screening test of fungicides,statistical analysis showed that the higher the altitude,the more severe disease plaster.The rate of diseased plants was positively linearly related to tree age.There was a certain correlation between the plaster disease and scale insects.The indoor virulence test showed that the virulence of triazole was higher than that of broad-spectrum fungicides such as chlorothalonil.The mass concentration of 215 mg/L tebuconazole had a good effect on the prevention and treatment of pepper plaster,reaching 89.26%after two times of continuous control,which could be applied in production.
