Weeding composition containing pyraclonil and clomazone and application thereof

The invention discloses a weeding composition containing pyraclonil and clomazone and application thereof. The weeding composition takes pyraclonil and clomazone as main active ingredients, and the mass ratio of clomazone to pyraclonil is 1:60 to 60:1. The weeding composition can be used for prior to soybean field pre-emergence weeding and especially has remarkable effects when used for controlling gramineous and broadleaf weeds in soybean fields. Relative to a single chemical pesticide, on the premise of improving pesticide effects, the weeding composition delays weed resistance, has a broad herbicidal spectrum and a long lasting period, and is safe for both soybean and post-crop crops.
