为了明确34%砜嘧·噻吩磺隆WG对玉米田一年生杂草的除草活性及对玉米的安全性,进行了2年田间药效试验。结果表明:34%砜嘧·噻吩磺隆WG对玉米田一年生杂草如马唐、稗草、小藜等均具有较好的防除效果,药后15 d、30 d的总草株防效分别为86.76%~100.00%、83.26%~99.34%,药后30 d的总草鲜重防效为84.82%~99.50%。玉米平均增产15.85%~29.02%。34%砜嘧·噻吩磺隆WG的防效和增产效果明显优于25%砜嘧磺隆WG和75%噻吩磺隆WG。其在玉米田最佳有效成分用量为30.6~51.0 g/hm2,在此用量下对玉米安全。

In order to clarify the herbicidal activity and safety of rimsulfuron + thifensulfuron-methyl 34% WG on annual weeds in maize field, the field experiments were conducted. The results indicated that rimsulfuron + thifensulfuron-methyl 34% WG had good control effects on annual weeds in maize field. The herbicidal efficiencies were 86.76%-100.00% and 83.26%-99.34% on the 15th and 30th day after spraying, respectively. The fresh weight efficiencies were 84.82%-99.50% on the 30th day after spraying, and the increasing rates of maize yield were 15.85%-29.02%. The control effects of rimsulfuron + thifensulfuron-methyl 34% WG were significantly better than rimsulfuron 25% WG and thifensulfuron-methyl 75% WG. The optimal active ingredient dose of rimsulfuron + thifensulfuron 34% WG were 30.6-51.0 g/hm2 in maize field with water usage of 600 kg/hm2.
