[目的]比较和评价氟唑菌酰胺及其混剂等6种杀菌剂对辣椒灰霉病的防治效果,探索42.4%唑醚·氟酰胺悬浮剂最佳使用剂量范围、施药时间和使用方法,评价对辣椒的安全性。[方法]以42.4%唑醚·氟酰胺悬浮剂5个剂量和30%氟唑菌酰胺悬浮剂等5种药剂各1个剂量,进行田间药效对比试验。[结果]30%氟唑菌酰胺悬浮剂、42.4%唑醚·氟酰胺悬浮剂对辣椒灰霉病防效好,持效期长。[结论]两种杀菌剂推荐使用剂量分别为有效成分112.5、225~450 g a.i./hm2。
[Objective] The research aimed to compare and evaluate the control effects of 6 fungicides such as PFZ and their mixture on gray mold disease of pepper capsicum, and explore the optimum dosage range, application time and method of 42.4% azole ether / flutamide suspension , Evaluate the safety of pepper. [Method] With 5 dosages of 42.4% azole ether and flutolanil suspension and 1 dose of 5 kinds of pesticides such as 30% flutolactam suspension, field efficacy test was conducted. [Result] The control effect of 30% PFX suspension and 42.4% oxazole ether and flutamide suspension on pepper gray mold was long-lasting. [Conclusion] The recommended dosages of the two fungicides were 112.5 and 225 ~ 450 g a.i./hm2, respectively.
