Navitrol is a Group 4 herbicide used for the control of aquatic plants, woody plants, and vines, as well as annual and perennial broadleaf weeds. It is formulated with 44.4% triclopyr (3,5,6-trichloro-2-pyridinyl)oxyacetic acid, triethylamine salt. This product is suitable for use in various environments including forests, non-crop areas (industrial, manufacturing, storage), rights-of-way (power lines, pipelines, roadsides, railroads), fence rows, and non-irrigation ditch banks. It can also be used in aquatic sites such as ponds, lakes, reservoirs, non-irrigation canals, and ditches with little to no continuous outflow. Application methods include ground spray and aerial applications. When applying to aquatic sites, users must be cautious of oxygen depletion caused by decomposing plant matter; it is recommended to treat in bands and wait at least 10 to 14 days between treatments. Handling requires specific PPE, including long-sleeved shirts, long pants, shoes plus socks, protective eyewear with side-shields or a full face shield, and chemical-resistant gloves (>14 mils) made of butyl rubber, natural rubber, neoprene, or nitrile rubber. The product is corrosive and can cause irreversible eye damage. Always follow specific site restrictions, such as avoiding application near irrigation systems or un-impounded rivers/streams, and observe specific grazing withdrawal periods for rangeland and pasture sites.
