摘要: 为筛选防控甘蔗螟虫和绵蚜的缓释长效低毒低风险多功能配方新药剂及精准高效施药技术,选用10%杀虫单.噻虫嗪颗粒剂和1%Bt.噻虫胺颗粒剂根施进行田间药效试验。田间试验结果表明,10%杀虫单.噻虫嗪颗粒剂和1%Bt.噻虫胺颗粒剂对甘蔗螟虫和绵蚜均具有良好的防控效果,是防控甘蔗螟虫和绵蚜理想的缓释长效低毒低风险多功能配方新药剂,与其他药剂交替使用,可延缓害虫抗药性产生和发展。两种药剂田间使用最适宜用量均为45 kg/hm2,可在1-7月结合新植蔗下种、宿根蔗管理或大培土,按每公顷用药量45kg与每公顷施肥量1200-1800 kg混合均匀一次性撒施于蔗沟、蔗桩或蔗株基部覆土或全膜盖膜,对螟害枯心苗的防效可达79.2%以上,对甘蔗绵蚜的防效可达98.8%以上;甘蔗实测产量和糖分分别较对照增加41555 kg/hm2和6.5%以上。缓释长效强内吸性多功能新药剂与底肥追肥混匀一次性根施,施用方便,精准高效,省工省时,环境友好,值得在蔗区大面积推广应用。

Abstract: To screen new multifunctional pesticides which are sustained-release, long-lasting, low-toxic and low-risk to control sugarcane borer and woolly aphid, and explore their accurate and efficient application technology, 10% monosultap·thiamethoxam GR and 1% Bt·clothianidin GR were used for root application in field efficacy trials. The results showed that 10% monosultap·thiamethoxam GR and 1% Bt·clothianidin GR had good control effect on sugarcane borer and woolly aphid, they were new multifunctional pesticides of ideal sustained-release, long-lasting, low-toxin and low-risk, and could used with other pesticides alternately to delay the generation and development of the resistance of pesticides. The optimum dosage of these two pesticides were both 45 kg/hm2. Combined with the sugarcane new planting and ratoon management or‘hilled up’soil between January and July, these two pesticides (45 kg/hm2) were mixed with regular fertilizer (1200-1800 kg/hm2) and applied one time in the sugarcane furrow, stump and the base of stalk, then covered with soil or whole plastic-film mulching. The control effect on borer-damaged dead heart seedling and woolly aphid could be more than 79.2% and 98.8%, respectively. The real yield and sucrose content increased by more than 41555 kg/hm2 and 6.5% compared with that in blank control respectively. These new multifunctional pesticides of sustained-release and long-lasting, which are mixed with base fertilizer and applied in the root one time, are convenient, accurate and effiefficient, labor and time saving, and environment friendly, and could be applied in sugarcane production region.
