| Abstract: | In order to select safe and effective herbicides, experiment was carried out to test some herbicides effect on large crabgrass and barnyardgrass at the stage of turfgrass germination and establishment. The result showed that, application of Oxyflu orfen 0.75 kg/hm 2, Oxadizon 3.00 kg/hm 2 and Butachlor 1.00 kg/hm 2 before emergence could control seed germination of large crabgrass and barnyardgrass. Application of Fenoxapropethyl 0\^30 kg/hm 2,Sethoxydim 0.30 kg/hm 2 and Propanil 1.50 kg/hm 2 respectively, could kill the seedling of large crabgrass and barnyardgrass. |
