Abstract: The effect of 3% florpyrauxifen EC on weed control in direct seeding rice field was studied. The results showed that 3% florpyrauxifen EC could effectively control a broad spectrum of weeds in the direct seeding rice filed. The weed control efficiency of Euphorbia lathyris,Ammannia arenaria,Polygonum hydropiper,Lindernia procumbens and Cyperus rotundus were totally up to 100% at 35 d by 36 g a.i./hm2 3% florpyrauxifen EC or 27 g a.i./hm2 3% florpyrauxifen EC mixed with 10% cyhalofop-butyl EC （112.5 or 225.0 g a.i./hm2）.

Key words: direct seeding rice, chemical herbicides, weed control efficiency, 3% florpyrauxifen EC
