Definitions

  • the present invention relates to a herbicide composition.
  • herbicidal active substances that can effectively control them and are safe for crops have been developed.
  • Many herbicides developed so far have been registered for specific crops and are used for weed control.
  • Herbicides for use in controlling weeds occurring in the cultivation areas of such specific crops have high herbicidal activity and a broad weeding spectrum, but are preferably safe for the environment and crops. However, not all herbicides fully satisfy these conditions.
  • the method most used is a method of mixing two or more herbicidal active substances having different herbicidal activities.
  • the herbicidal active substances there are cases in which a better herbicidal effect is exhibited than when the herbicides are individually treated (single treatment) to weeds. This case of exhibiting more than the level of potency or activity that would be expected according to the results of the individual potency of the constituents is referred to as "synergy”.
  • Pyribenzoxim is a herbicide from germination to postemergence and has the action of inhibiting Acetolactate synthase (ALS) activity. Due to its strong soil adsorption properties, it is mainly used for foliage treatment. Conventionally, Pyribenzoxim (PBX) was mainly developed as a single agent, but recently, research on the development of a combination with other herbicidal active substances is being conducted for the emergence of resistant weeds and expansion of the weeding spectrum.
