Definitions

  • WG water dispersible granule
  • SC compositions are prone to settling of the dispersed solids during storage due to gravity. They require mixing and/or shaking before use in order to resuspend the settled material. In addition, SC compositions tend to leave about 3-5% residue when poured out of a container. SC compositions also present issues with safety and cleanup due to their liquid form.
  • Granular compositions such as water dispersible granule (WG) compositions (A formulation consisting of granules to be applied after disintegration and dispersion in water), do not share the issues of SC compositions with settling, residue, safety, or cleanup. Thus, they present numerous benefits over SC compositions.
  • WG water dispersible granule
  • Effective WG compositions depend on the identity and amounts of the active ingredients and other components. However, effective WG compositions are often difficult to predict and formulate. As one example, conventional WG compositions including high amounts of bixlozone have not been formulated.
  • WG compositions including high amounts of bixlozone have been surprisingly discovered herein. These compositions overcome past limitations with SC compositions and WG compositions including low amounts of bixlozone.
  • the present disclosure is directed to a water dispersible granule composition
  • a water dispersible granule composition comprising: (i) from greater than 50 wt% to about 90 wt% of bixlozone; (ii) from about 0.01 wt% to about 5 wt% of a wetting agent; (iii) from about 1 wt% to about 20 wt% of a dispersant; and (iv) from about 1 wt% to about 20 wt% of a carrier.
