The performance standard for right-of-way vegetation management

The state-of-the-art formulation of Garlon 4 Ultra 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.

Improved overall performance

Garlon 4 Ultra is labeled to effectively control more than 55 woody plants and more than 25 tough-to-control annual and perennial broadleaf weeds in noncrop areas that include roadsides, railroads, pipelines, industrial sites, forests and rights-of way such as power lines. It also is labeled for the establishment and maintenance of wildlife openings and can be used on sites that include grazed areas.The state-of-the-art formulation, offered exclusively from Dow AgroSciences, is based on methylated seed oil (MSO) as the solvent. In field tests, the Garlon 4 Ultra formulation demonstrated increased effecacy on high-anxiety woody species that include cherry, loblolly pine, mesquite, red oak, sweetgum and Scotch broom. At the same time, Garlon 4 Ultra provides the same high level of control that users of Garlon 4 specialty herbicide have come to expect for problem vegetation that include alder, ash, birch, blackberry, ceanothus, chinquapin, clover, dandelion, dogwood, elm, kudzu, maple, oak, poison ivy, ragweed and wild violet.

Conforms to changing environmental regulations

The advanced Garlon 4 Ultra specialty herbicide formulation uses no petroleum distillates important for compliance in states that have or are considering mandated reductions of Volatile Organic Compound (VOC) emissions into the atmosphere. The plant-derived solvent formulation results in a milder scent to help reduce the possible public objections associated with the strong odor of a petroleum-based solvent. The MSO solvent is less phytotoxic to foliage than petroleum-based formulations, and, therefore, the superior control can be attributed to improved uptake of active ingredient into plants. Because Garlon 4 Ultra uses triclopyr as the active ingredient, the same used in Garlon 4, the two herbicides share an extensive toxicology database and similar toxicology attributes. Garlon 4 Ultra is labeled with a Caution signal word.

Applications for long-lasting brush control

Conventional methods of roadside vegetation control like mowing and trimming remain important for maintenance, but are not always the best option. Steep terrain and railroads can make mowing dificult and even dangerous. Mechanical methods also can encourage resprouting, worsening the problem. Garlon 4 Ultra specialty herbicide effectively eliminates unwanted brush from labeled application sites to reduce visits by crews and heavy machinery. Garlon 4 Ultra works by limiting the nutrients available to target plants, essentially starving the plant until it is eliminated.

The Garlon 4 Ultra label allows for basal bark, cut-stump and foliar applications. Basal bark applications are hand-sprayed to the lower 15 inches of the bark at the base of the tree or brush. Cut-stump applications are made after tree removal with herbicide application to the cut stump surface and remaining bark to prevent tree resprouting. Foliar application directions allow herbicide application to plant foliage using ground or aerial (helicopter) equipment. Because Garlon 4 Ultra contains 4 pounds active ingredient per concentrate gallon, applicators familiar with Garlon 4 herbicide will and calibrating finished application rates to be the same. In basal oil mixtures, Garlon 4 Ultra specialty herbicide mixes as easily as does Garlon 4 and its cold weather handling characteristics are similar to that of Garlon 4. Label directions for Garlon 4 Ultra include tank-mixed with herbicides such as Tordon 101M, Tordon K and 2,4-D (please refer to the label for specic tank-mix directions).
