300g/L呋喃磺草酮·氟酮磺草胺悬浮剂防治直播水稻田杂草应用技术

Study on Application Technology of Tefuryltrione+Triafamone 300 g/L SC to Control Weeds in Direct Seeding Paddy Fields

300 g/L呋喃磺草酮·氟酮磺草胺悬浮剂是拜耳股份公司生产的新型稻田除草剂,为了明确其在直播水稻田使用的除草效果以及对后茬作物生长的影响,开展了本试验。结果表明,300 g/L呋喃磺草酮·氟酮磺草胺悬浮剂对稗草、耳基水苋、鸭舌草和异型莎草等均有较好的防治效果,且对供试水稻品种沪早香软1号生长安全。300 g/L呋喃磺草酮·氟酮磺草胺悬浮剂防治直播水稻田杂草的适宜剂量为90~108 g a.i./hm^2。直播水稻田使用300 g/L呋喃磺草酮·氟酮磺草胺悬浮剂后,后茬可种植油菜、小麦和蚕豆等作物。

Tefuryltrione+triafamone 300 g/L SC is a new herbicide for paddy fields produced by Bayer AG.Field experiments were conducted to evaluate its efficacy on weeds in direct seeding rice fields and the selectivity to rice and succeeding crops.Tefuryltrione+triafamone 300 g/L SC effectively controlled Echinochloa crus-galli(L.)Beauv.,Ammannia arenaria H.B.K.,Monochoria vaginalis(Burm.f.)Presl,Rel.Haenk.,and Cyperus difformis L.,and was selective to rice cultivar“Huzaoxiangruan No.1”.The optimum dosage for weed control in direct seeding paddy fields was 90~108 g a.i./hm^2.The residues of the herbicide had no adverse effects on the succeeding crops such as rape,wheat,and broad beans.
