摘　　要：为明确30%苯唑·烟·特丁可分散油悬浮剂的田间药效及安全性,采用茎叶喷雾法进行田间药效试验。药后15、30 d对玉米的生长和杂草的防效进行调查。结果表明,30%苯唑·烟·特丁可分散油悬浮剂可有效防治稗草[Echinochloa crusgalli(L.)Beauv]、马唐[Digitaria sanguinalis(L.)Scop.]、苘麻(Abutilon theophrasti Medicus)和铁苋菜(Acalypha australis L.)。在药后15 d对杂草的总防效为90.81%~98.16%,药后30 d对杂草的总防效为88.88%~97.78%,对杂草的鲜重防效为90.42%~98.82%。在生育期内,30%苯唑·烟·特丁可分散油悬浮剂各浓度处理对玉米安全。In order to clarify the field efficacy and safety of 30%topramezone·nicosulfuron·terbuthylazine dispersible oil suspension concentrate,the field efficacy test was carried out by using the stem and leaf spray method.The growth of corn and the control effect of weeds were investigated at 15 and 30 days after treatment.The results showed that 30%topramezone·nicosulfuron·terbuthylazine dis⁃persible oil suspension agent can effectively control Echinochloa crusgalli(L.)Beauv.,Digitaria sanguinalis(L.)Scop,Abutilon theo⁃phrasti Medicus and Acalypha australis L..The total control effect against weeds at 15 days after the treatment was 90.81%~98.16%,the total control effect against weeds at 30 days after the treatment was 88.88%~97.78%,and the fresh weight control effect against weeds was 90.42%~98.82%.During the growth period,the treatment of 30%topramezone·nicosulfuron·terbuthylazine dispersible oil suspension concentrate in various concentrations was safe for corn.
