摘　　要：为了一体化防控玉米中后期病虫害,在玉米大喇叭口期至抽雄期,应用植保无人机,优化广谱、内吸传导性强、持效期长的杀菌剂与杀虫剂,并与微肥、飞防增效剂混配,开展了玉米中后期病虫害控害增效药剂组合筛选试验。结果表明,17%唑醚·氟环唑悬浮剂900 mL/hm^(2)+40%氯虫·噻虫嗪水分散粒剂180 g/hm^(2)+氨基酸液肥495 mL/hm^(2)+迈飛飞防专用增效剂300 mL/hm^(2)组合、43%唑醚·氟酰胺悬浮剂360 mL/hm^(2)+40%氯虫·噻虫嗪水分散粒剂180 g/hm^(2)+氨基酸液肥495 mL/hm^(2)+迈飛飞防专用增效剂300 mL/hm^(2)组合,对玉米大斑病、灰斑病的防治效果为79.8%~88.2%,对玉米螟、双斑萤叶甲的防治效果为92.3%~94.3%,增产率达15.2%,一次施药可达到防病、防虫、增产的效果。In order to integrally prevent and control maize diseases and pests,this paper applied plant protection drones from the trumpet stage to the male extraction stage of maize,optimized the fungicides and pesticides with broad spectrum,strong internal suction conductivity and long effective period,and mixed them with micro fertilizers and fly prevention synergistic agents,conducted a screening experiment on synergistic pesticide combinations for control of di-seases and pests in maize in the middle and late stage.The results showed that,the control effect of 17%pyraclostrobin·epoxiconazole SC 900 mL/hm^(2)+40%chlorantraniliprole·thiamethoxam WG 180 g/hm^(2)+amino acid fertilizer 495 mL/hm^(2)+Maifei fly anti-specific synergist agent 300 mL/hm^(2) combination、43%pyraclostrobin·fluxapyroxad SC 360 mL/hm^(2)+40%chlorantraniliprole·thiamethoxam WG 180 g/hm^(2)+amino acid liquid fertilizer 495 mL/hm^(2)+anti-specific synergist agent 300 mL/hm^(2) combination on maize large spot disease and gray spot disease ranged from 79.8%to 88.2%,the control effects of two combinations on maize borer and firefly beetle were 92.3%-94.3%,and the yield rate reached 15.2%,one application could achieve the effects of disease prevention,pest control,and yield increase.
