摘要
水稻移栽田除草试验结果表明:在3种施用剂量中,以施用苄.苯噻酰WP 750 g/hm2对5种杂草的防除效果最好,药后14 d的防效达92.8%以上。施用苄.苯噻酰WP 750 g/hm2对稗草的防效与对照药剂苯噻酰草胺750 g/hm2的相当,对陌生菜、节节菜、牛毛毡等阔叶杂草的防效与对照药剂苄嘧磺隆225 g/hm2的接近,对异型莎草也有较高的防效,而且比对照增产稻谷11.1%。
The results of weed control tests in the transplanted rice field showed that： among the tested 3 dosages, the application of 750 g/hm2 Bensulfuron methyl · Mefenacet WP had the best control effect on the 5 kinds of weeds, and its control effect was more than 92.8% on the 14th day after spraying. The control effect of applying 750 g/hm2 Bensulfuron methyl · Mefenacet WP on Echinochloa crusgalli was similar with that of applying 750 g/hm2 Mefenacet （check phytocide）. In comparison with applying the check herbicide Bensulfuron methyl at the dosage of 225 g/hm2, applying 750 g/hm2 Bensulfuron methyl · Mefenacet WP had nearly same control effects on broad - leaf weeds, such as Rotala indica, Eleocharis yokoscensis and so on, it also had good control effect on Cyperus difformis, and it could obtain 11.1% higher rice yield than CK.
