Abstract
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.关键词
