| 选择噻虫嗪及其复配制剂，采用不同施药方法对稻蛀茎夜蛾、甘蔗粉角蚜和甘蔗蓟马进行防治。结果表明，结合甘蔗下种，30%氯虫·噻虫嗪悬浮剂600~750mL/hm2、40%氯虫·噻虫嗪水分散粒剂600~750g/hm2与底肥一起施用，对苗期稻蛀茎夜蛾防效为70%～75%; 结合甘蔗大培土，25%噻虫嗪水分散粒剂600g/hm2、70%噻虫嗪种子处理可分散粉剂225~300g/hm2、30%氯虫·噻虫嗪悬浮剂600~750mL/hm2、40%氯虫·噻虫嗪水分散粒剂600g/hm2与追肥一起施用，药后45d对甘蔗粉角蚜防效达98%以上，对甘蔗蓟马防效达70%以上; 在甘蔗伸长期，25%噻虫嗪水分散粒剂600g//hm2、70%噻虫嗪种子处理可分散粉剂225~300g//hm2、30%氯虫·噻虫嗪悬浮剂600~750mL/hm2对水450kg/hm2淋浇甘蔗根区，药后15 d对甘蔗粉角蚜防效为90%以上。农药根施防治甘蔗害虫，方法简单易行，持效期长，且对环境友好，是一种简便高效的害虫防治施药技术。 |

| Thiamethoxam and its mixtures were applied to control sugarcane insect pests Sesamia inferens Walker, Ceratovacuna lanigera Zehntner and Baliothrips serratus Kobus. The results showed that control effects of 30% chlorantraniliprole·thiamethoxam SC 600-750 mL//hm2 and 40% chlorantraniliprole·thiamethoxam WG 600-750 g/hm 2 combined with base fertilizer application when seed canes were planted were 70%-75% on S. inferens at seedling stage. At the earthing up stage, control efficacies of application of 25% thiamethoxam WG 600 g//hm2, 70% thiamethoxam WS 225-300 g//hm2, 30% chlorantraniliprole·thiamethoxam SC 600-750 mL//hm2 and 40% chlorantraniliprole·thiamethoxam WG 600-750 g/hm 2 with topdressing were over 98% on C. lanigera and over 70% on B.serratus after 45 days, respectively. At the elongation stage, root applications of 450 kg//hm2 water solutions of 25% thiamethoxam WG 600 g//hm2, 70% thiamethoxam WS 225-300 g//hm2 and 30% chlorantraniliprole·thiamethoxam SC 600-750 mL//hm2 achievedcontrol efficacies of over 90% on C. lanigera after 15 days. These results suggested that root application of thiamethoxam and its mixtures is an easy handling, highly effective, long duration and environmentally friendly method for controlling sugarcane insect pests. |
