为探索苯胺类除草剂48%仲丁灵乳油在北方移栽水稻田应用的可行性,2008年通过田间试验对该药剂的杀草谱、除草效果及对水稻生长的安全性进行了研究.结果表明,在水稻移栽后7 d施用48%仲丁灵乳油3 000～3 750 g·hm-2(有效成分1 440～1 800 g·hm-2),对移栽水稻田一年生禾本科杂草稗草具有较高的防除效果,对阔叶杂草野慈姑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.

In order to research the application feasibility of 48% Butralin EC of aniline herbicidesn in the north transplant rice field,the trial of 48% Butralin (EC) on weeds was done to study the herbicide controlling spectrum,weeding effect and safety on rice growth.The results showed that,with the use dosage of 3 000 ～3 750 g · hm-2(active ingredient 1 440 ～ 1 800 g · hm-2)and applying in 7 days rice transplanting,the 48% Butralin (EC)had high control effect on the annual Gramineae weeds barnyardgrass(Echinochloa crus-galli L.),and had obvious control effect on broad-leaf weeds wild arrowhead(Sagittaria trifolia L.),and was safety on transplant rice growth and could be promoted on the basis of demonstration.
