Background The information provided in this background section is only for enhancement of understanding of the general background of the invention and should not be taken as an acknowledgement or any form of suggestion that this information forms the prior art already known to a person of ordinary skill in the art. Chemical weeding is the most economical and effective means in farmland weed control, but as a plurality of weeds are mixed in a paddy field generally, the resistance of the weeds in the paddy field is increased, the control difficulty is increased, and the weeds in the paddy field cannot be controlled once by a single effective component. Reasonable compounding or compounding of herbicide compounds can have the advantages of improving the efficacy, delaying the resistance, expanding the weed killing spectrum and the like, and is an important means for solving the weed problem. Therefore, there is an urgent need for a good herbicide composition effective in controlling weeds in paddy fields in agricultural production. The active ingredient oxazophos is HPPD high-selectivity systemic conduction type paddy field herbicide innovatively developed by Shandong Kogyo technology Co-Ltd, has high safety to paddy rice, mainly causes new She Baihua weeds through absorption of plant roots and stems, and has good effects on annual weeds such as barnyard grass, moleplant, special-shaped nutgrass flatsedge, snakehead intestines and the like.
