Topramezone-containing weeding composition and application thereof

The present invention relates to the technical field of herbicides, particularly to a topramezone-containing weeding composition and an application thereof, the effective components of the weeding composition comprise topramezone, halosulfuron-methyl and terbuthylazine, and the weight ratio of topramezone to halosulfuron-methyl to terbuthylazine is (0.45-7.2): (0.6-9.6): (25-400), and the application is the application of the weeding composition in preventing and removing weeds in a corn field. The terbuthylazine is used as a triazobenzene herbicide, is absorbed by roots of plants, is appliedto crop fields such as corn, peanut, pea, broad bean, sugarcane, orange and the like before sprouting to control most annual gramineous weeds and broadleaf weeds, and is matched with the control effect of topramezone and halosulfuron-methyl to realize the synergism of the weeding composition; the use amount of pesticide is reduced, so that the generation of drug resistance is greatly delayed. 本发明涉及除草剂技术领域，具体涉及一种含有苯唑草酮的除草组
