  • compositions comprising bixlozone and beflubutamid. Also described herein are methods of preparing the compositions. Also described herein are methods for controlling undesirable vegetation with the compositions.
  • Bixlozone and beflubutamid are not compatible active ingredients because the melting point of each active ingredient is reduced upon mixing them together.
  • suspension concentrate formulations prepared either by milling both the active ingredients together or by mixing the individually milled suspension concentrates are not stable at both high temperatures and ambient storage temperatures. This incompatibility limits the feasibility of suspension concentrate formulations containing both bixlozone and beflubutamid.
  • contacting these two active ingredients together promotes formation of a eutectic mixture such that the melting point of the mixture is reduced below the individual components. Consequently, there are no commercially available pre-mix formulations containing both bixlozone and beflubutamid.
