In older dicamba formulations, dicamba ions (Dc- ) are present in solution, combine with free hydrogen ions (H+) to form volatile dicamba acid (DCH) VaporGrip™ Technology prevents dicamba ions (Dc- ) from combining with hydrogen ions (H+), significantly reducing volatility.


Annual broadleaf weeds:

Canada fleabane1,2, cleavers, common lamb’squarters, common ragweed1 , corn spurry, cow cockle, giant ragweed1 , green smartweed, kochia1,6, lady’s-thumb, pigweed (redroot, Russian, smooth), velvetleaf, wild buckwheat, wild mustard
