The invention relates to weed control foliar herbicide compositions in a paddy field, which are three foliar herbicide compositions for eliminating weeds in the paddy field. The three foliar herbicide compositions are the composition of mesotrione and metamifop, the composition of mesotrione and cyhalofop-butyl and the composition of mesotrione and penoxsulam respectively. The single use of the existing herbicide in the paddy field has the limited weed-killing spectrum and can not control all the weeds in the paddy field, and a complex product has poor safety or a narrow using cycle or resistance to the weeds in a water field, thereby limiting the popularization and the applications of the complex product. The three herbicide compositions provided by the invention can overcome the defects and control all the weeds in the paddy field; furthermore, the three herbicide compositions have broader using cycle, no resistance to the weeds in the water field and good safety to paddy rice and succeeding crops.
