Herbicide composition containing pyrimidinedione-based compound

The present invention relates to a herbicide composition containing a drug efficiency enhancing agent and a pyrimidinedione-based compound as an active ingredient. The herbicide composition according to the present invention can increase the biological effect exhibition properties of a pyrimidinediacone-based composition, which is a contact-type drug, allows spreading and penetrating activities to improve such that fast-acting properties of broad-leaf weeds and narrow-leaf weeds can improve, and can effectively control, at a low dose, weeds exhibiting resistance to other herbicides. In addition, the present invention possesses thermodynamic stability so as to have increased storage stability, and allows the active ingredient to be uniformly dispersed so as to be capable of exhibiting uniform and excellent drug efficacy during drug administration.
