摘要
70.5% 2甲·唑酮(哈利)WG防治夏玉米田香附子的试验结果表明:在香附子9～11叶期,使用70.5%哈利WG675～900g/hm2,茎叶喷雾,用药后45d防效为85.2%～93.5%,有较好的防除效果,收获时测产表明对玉米有增产效果,田间观察对玉米安全;大面积示范也取得了良好的效果。
The field trial showed that Harrier（MCPA-Na and carfentrazone-ethyl） 70.5% WG had a good control effect against weed Cyperus rotundus L. in summer corn field. Harrier 70.5% WG applied during 9-11 leaf of weed Cyperus rotundus L. had 85.2-93.5% control efficacy after treat 45 days. It was safe for corn and weed control with the herbicide significantly improved corn yield. The greater area application also has the good result.
