Adjuvant Compositions and Related Methods for Reducing Herbicide Volatility




Herbicides are applied to crop fields to prevent the growth of weeds. This helps to increase target crop yields. These herbicides act by preventing plants from photosynthesizing, growing, or by directly killing the plant. The seed industry is in the process of releasing crops that are resistant to 2,4-D and/or dicamba. However, these herbicides are volatile compounds.  Under the wrong weather conditions herbicide vapors can migrate to local, non-target plants and fields, and can thereby damage adjacent non-resistant crop plants. There is an industry interest and ecological benefit to reducing the volatility of these herbicides.


Description of Technology


This technology is an adjuvant used in solution with 2,4-D and/or dicamba to reduce the volatility of herbicides after application. Notably, the adjuvant does not form a salt with either herbicide, and is therefore more compatible with water conditioners than high molecular weight herbicide salts.  This technology reduces application concentrations of the herbicide and reduces secondary non target application on local fields.


Key Benefits

  • Reduction in herbicide volatility – keeps more herbicide on target plants longer
  • Reduces non target affects – prevents unintended herbicide application to non-target plants
  • Broad compatibility – Adjuvant Can be used with a multitude of herbicides, including glyphosate



  • Adjuvant to reduce herbicide volatility and spread to non-target plants
