Definitions

  • the present invention relates to the field of crop protection compositions.
  • the invention relates to emulsifiable concentrate (EC) formulations comprising herbicidally active compounds from the group of the sulfonylaminocarbonyltriazolinones.
  • active compounds for crop protection are not employed in pure form.
  • the active compound is used as an active compound formulation in a mixture with customary auxiliaries and additives.
  • further active compounds for widening the activity spectrum and/or for protecting crop plants (for example by safeners, antidotes).
  • Formulations of individual active compounds should generally be easy to apply and easy to use and have broad biological action combined with high selectivity with respect to the active compounds used, and should additionally be easy to formulate in the preparation process. Of particular importance here is high chemical and physical stability (storage stability) of the formulation.
  • Typical formulations in crop protection are concentrated suspensions (active compound suspensions) in which the active compound particles (discontinuous phase) are suspended in an external liquid phase (continuous phase).
  • the suspensions are classified as suspension concentrates (SC), where the main component of the external phase is water, or oil dispersions (OD), where the main component of the external phase is an organic solvent.
