Abstract

The invention discloses a weed controlling compound pesticide composition. The pesticide composition contains such active ingredients as fluroxypyr or esters thereof and topramezone, wherein the weight ratio of fluroxypyr or esters thereof to topramezone is 15: (1-3). The pesticide composition is characterized in that the dosage form of the pesticide composition is wettable powder or water dispersible granules; based on the total weight of the composition, the content of fluroxypyr or esters thereof is 10-70%, the content of topramezone is 2-30% and the content of additives is 10-88%; and theamount of the esters of fluroxypyr is converted into the amount of fluroxypyr. The invention also discloses a preparation method of the wettable powder or water dispersible granules. The pesticide composition is formed by compounding fluroxypyr or esters thereof and topramezone, has low toxicity, wide weed control spectrum, quick effect, good persistence and medium cost, can control broadleaf weeds, annual grass weeds and the like, is a more ideal pesticide variety for controlling weeds in the maize fields and has the advantages of simpleness in production, convenience and safety in use, zeroenvironmental pollution and the like.
