Definitions

  • the present invention relates to the use of an agrochemical composition comprising at least one specific herbicide and at least one specific fungicide for controlling undesired vegetation in rapeseed cultures and for the desiccation and/or defoliation of rapeseed.
  • the invention further relates to a method for controlling undesired vegetation in rape- seed cultures and to a method for the desiccation and/or defoliation of rapeseed plants.
  • herbicidal compositions In the case of crop protection, such as herbicidal compositions, it is desirable in principle to increase the specific activity of an active compound and the reliability of the effect. For an herbicidal composition, it is particularly desirable to control harmful plants effectively, but at the same time to be compatible with the useful plants in question. Also desirable is a broad spectrum of activity allowing the simultaneous control of harmful plants. Frequently, this cannot be achieved using a single active compound.
  • the active compounds act as antidotes or antagonists and are also referred to as safeners, since they reduce or even prevent damage to the crop plants.
  • Rapeseed are among the most important crop plants. Improving their growth conditions is thus an ongoing need. It is an object of the present invention to provide agrochemical compositions which are highly active against unwanted harmful plants in rapeseed cultures. This and further objects are achieved by the agricultural composition described below. Surprisingly, this composition has better herbicidal activity, i.e. a better activity against harmful plants, than would have been expected based on the herbicidal activity observed for the individual compounds, or a broader activity spectrum.
  • the time frame, within which the desired herbicidal action can be achieved may be expanded by said composition. This allows a more flexibly timed application of the compositions according to the present invention in comparison with the single compounds.
  • Said composition also has a better compatibility with useful plants.
