Signal Word - CAUTION / PRECAUCION

Garlon 4 Ultra 60.45% Triclopyr Specialty Herbicide was developed by Dow AgroSciences to deliver enhanced performance on unwanted vegetation along roadsides, industrial rights-of-way and similar noncrop sites. The advanced, patented formulation also helps ensure the continued availability of the workhorse active ingredient triclopyr for professional right-of-way vegetation management.


Garlon 4 Ultra is available exclusively from Dow AgroSciences to meet the changing needs of vegetation management professionals, the public and the environment. The innovative formulation uses a plant-derived solvent as a proactive measure to reduce organic compounds and petroleum distillates, reduce odor and improve overall performance. Dow AgroSciences also has updated and improved the label directions as part of its ongoing stewardship initiative.


We recommend the use of a spray adjuvant that helps break down waxy cuticle on leaf surfaces like Cide-Kick II with this product.
