摘　　要：[目的]通过田间药效试验明确98%棉隆对马铃薯原原种疮痂病的防治效果,为棉隆在马铃薯生产上的应用提供科学依据。[方法]通过2年的田间试验,分别对土壤和二次用蛭石进行处理,测定了棉隆在马铃薯原原种生产中对疮痂病的防治效果。[结果]98%棉隆对马铃薯疮痂病具有较好的防治效果,45 g/m^2的棉隆可用于土壤或二次用蛭石处理,其防效可达80%以上。[结论]98%棉隆可以作为马铃薯原原种生产土壤或基质消毒剂使用,可有效防除马铃薯疮痂病,推荐使用剂量为45 g/m^2。[Aims] This study aims to confirm the field efficacy of dazomet 98% for control of the scab of potato and to provide scientific basis for application of dazomet in potato production. [Methods] The control effect of dazomet on scab in potato production was determined by using vermiculite treatment and soil treatment for 2 years. [Results] Dazomet 98% has good control effect on potato scab, dazomet 45 g/m^2 can be used in soil or old vermiculite treatment, its control effect can reach more than 80%. [Conclusions] Dazomet 98% can be used as a disinfectant for soil or substrate in the Mini-Tuber potato production. It can effectively prevent potato scab disease, and the recommended dose is 45 g/m^2.
