在玉米抽雄期喷施化学农药防治玉米生长中后期的几种病虫害，结果表明，40％氯虫·噻虫嗪WG 225 g/hm2剂量对玉米螟虫和蚜虫均有较高的防治效果，田间防效分别为81．08％和89．91％，小区产量比对照增加20．8％.10％吡虫啉WP 450 g/hm2剂量对蚜虫的防效为63．64％，对玉米螟虫效果较差.12．5％烯唑醇WP 450 g/hm2剂量对玉米锈病的防效为76．60％.30％苯甲·丙环唑对小斑病和弯孢霉叶斑病的防效分别为62．04％和51．72％.氯虫·噻虫嗪与烯唑醇混合喷施对中后期的玉米螟虫、蚜虫和锈病具有较好的控制作用.

The chemicals were sprayed to control maize borer,Rhopalosiphum spp.,Bipolaris maydis,Curvularia lunata,Puccina polysora of maize in the middle and later growing periods. The result indicated that 40%Chlorantraniliprole·Thiamethoxam WG 225 g/hm2 had better effect to maize borer and Rhopalosiphum spp.,the control effects were 81.08% and 89.91%,respectively. The plot yield increased 20.8% than that of the contrast averagely. The control effect of 10%Imidacloprid WP 450 g/hm2 dosage to Rhopalosiphum spp. reached 63.64%, but almost had no effect to maize borer. The control effect of 12.5%Diniconazole WP 450 g/hm2 to Puccinia polysora reached 76.60. The 30% Difenoconazole·Propiconazole EC had higher control effect to Bipolaris maydis and Curvularia lunata,the control effects were 62.04% and 51.72,respectively. The mixed usage of Chlorantraniliprole· Thiamethoxam and Diniconazole could control maize borer,Rhopalosiphum spp. and Puccina polysora of maize effectively.
