摘要
为探索48%仲丁灵乳油在南方稻田应用的可行性,2011年通过田间试验了该药剂对稻田杂草的防除效果及对水稻生长的安全性。结果表明,在水稻移栽后7 d施用48%仲丁灵乳油1 080~3 600 g(ai)/hm2,对稻田一年生禾本科杂草稗草、马唐具有较好的防除效果,对阔叶杂草鸭跖草、节节菜和莎草科杂草异型莎草、牛毛毡具有明显的兼治作用,对水稻生长安全,可以在示范的基础上推广应用。
To study the application feasibility of Butralin 48% EC to the rice fields in South China,the efficacy of Butralin 48% EC on weeds and its effects on the safety of rice growth were tried in 2011.The results showed that Butralin 48% EC applied at 1080-3600 g(ai)/hm2 to rice in 7 days after its transplanting had high efficacy on the annual gramineous weeds(Echinochloa crusgalli and Digitaria sanguinalis),and had obvious efficacy on broad-leaved weeds(Commelina communis and Rotala indica) and Cyperaceae weeds(Cyperus difformis and Eleocharis yokoscensis),and this application was safe for the rice growth.So Butralin 48% EC could be extended on the basis of further demonstration.
