摘　　要：【目的】测定增效剂、微肥及茎叶喷雾与种衣剂包衣协同施用对玉米茎腐病防效的实际提升效果,为新疆玉米茎腐病高效防治提供依据。【方法】以种子包衣用药为基础,采用田间小区防治试验,分别测定其与2种增效剂、2种微肥及5种茎叶杀菌剂协同施用对玉米茎腐病的田间防效。【结果】使用18%噻灵·咯·精甲FS 200 mL、5 g/L咯菌·精甲霜FS 150 mL对每100 kg种子包衣时,添加激健4000倍液/大消3000倍液可使防效较未添加增效剂相比,分别提高5.49%~5.84%和5.03%~6.54%;使用种衣剂+农用硫酸锌5 mL/150 mL或可溶性硅5 mL/150 mL底肥处理后的防效较种衣剂单独使用时增加2.05%~4.86%或2.60%~2.96%;使用种衣剂+茎叶喷雾联合处理后的防效较种衣剂单独使用亦均有一定程度的提高,分别增加1.06%~6.53%。【结论】在种衣剂拌种防治的基础上,结合添加激健4000倍液/大消3000倍液,或使用硫酸锌作为底肥,或使用10%苯醚甲环唑2000倍液进行茎叶喷雾处理均可作为新疆玉米镰刀茎腐病田间防效提升的配套方法。【Objective】The actual improvement effect of synergist,microelement fertilizer,stem and leaf spray and seed coating agent coating on the control effect of corn stem rot was determined,in order to establish a set of efficient control technology of corn stem rot in Xinjiang.【Methods】Based on the scientific use of seed coating drugs,field trials were conducted to determine the field efficacy of its synergistic application with two synergists,two micro fertilizers,and five stem and leaf fungicides against corn stem rot disease.【Results】When using 200 mL of 18%Thiamethasone,Chloramphenicol,and Vitamin A FS and 150 mL of 5 g/L Chloramphenicol,Chloramphenicol,and Vitamin A Cream FS to coat every 100 kg of seeds,adding a 4000 fold dilution of Jijian solution/3000 fold dilution of Daxiao solution can increase the efficacy by 5.49%-5.84%and 5.03%-6.54%,respectively,compared to not adding a synergist;The control effect of using seed coating agent+agricultural zinc sulfate 5 mL/150 mL or soluble silicon 5mL/150 mL base fertilizer treatment increased by 2.05%-4.86%or 2.60%-2.96%compared to using seed coating agent alone;The control effect of the combined treatment of seed coating agent+stem and leaf spray was also improved to a certain extent compared with that of seed coating agent alone,increased by 1.06%-6.53%respectively.【Conclusion】On the basis of seed coating agent seed dressing control,combined with the addition of 4,000 times of Jijian solution/3,000 times of Daxiao solution,or the use of zinc sulfate as the base fertilizer,or the use of 10%difenoconazole 2,000 times of solution for stem and leaf spray treatment,can be used as a supporting method to improve the field control effect of corn stalk rot in Xinjiang.
