Control is best when weeds are actively growing.
Early postemergence to 6 leaf corn recommended. Residue carryover into the next season is not a problem when applied at registered rates. This product has a wider application window, a lower use rate and has better activity on perennial weeds than dicamba alone. Spray drift is toxic to sensitive plants in the same manner as 2,4-D, thus similar precautions should be followed. The auxin transport inhibitor, diflufenzopyr, will also be active with other growth hormone herbicides such as 2,4-D and clopyralid and may cause crop injury if tankmixed.
