Weeding composition containing halauxifen-methyl and benzobicylon

The invention relates to a weeding composition. Active components in the weeding composition are halauxifen-methyl and benzobicylon, and a weight ratio of the halauxifen-methyl to the benzobicylon is 1:4 to 4:1. The weeding composition and a third component form a ternary weeding composition, the third component is pyraclonil, pretilachlor or oxaziclomefone, and a weight ratio of the halauxifen-methyl to the benzobicylon to the third component is (1-4):(1-4):(1-2). The weeding composition is preferably processed to prepare a water suspension, and the water suspension comprises a specific wetting dispersant. The binary weeding composition containing halauxifen-methyl and benzobicylon has excellent synergistic effects, and has a cotoxicity coefficient of 130 or more; the ternary weeding composition is obtained through adding the third component pyraclonil, pretilachlor or oxaziclomefone to the binary weeding composition, so the ternary composition has better synergistic effects than the binary composition (used
