Low volume foliar utility brush applications Â
Brush control on utility rights-of-way is currently in it’s Golden Age. The industry now boasts a wide array of products, advanced application techniques, and cutting-edge equipment to effectively manage vegetation in nearly any scenario.   Â
The right tools
Some of the most effective application techniques for foliar treatments include aerial broadcast, skidder broadcast, truck mounted selective high volume and backpack selective low-volume applications. These methods ensure precise and efficient treatment of vegetation, ultimately leading to improved maintenance of utility rights-of-way.
The first decision
Choosing the most effective products for controlling brush species is the first step in the process. The foundational products for utility brush control include Arsenal® AC, Method®, TerraVue™, Escort® XP, Vastlan®, Detail® and Roundup Custom®. There are various tank-mix options available that can effectively control nearly every unwanted species. Based on this selection, an appropriate application technique can be employed to ensure selectivity, optimize efficiency, and minimize costs.
Selectivity
There are two methods for achieving selectivity in brush control. The first method involves selecting the appropriate product. Products such as TerraVue™ and Method® are specifically designed for controlling brush and broadleaf weeds without impacting the grass. The second method for achieving selectivity is by product placement.
Targeting only the vegetation that may obstruct the flow of electricity ensures that desirable plants remain unharmed. This method allows for the use of effective products like Arsenal AC and Roundup.
Low volume applications
There are two methods for achieving selectivity in brush control. The first method involves selecting Low volume applications are commonly applied using backpacks. The total volume per acre typically ranges from 5 to 20 gallons in areas with light to moderate density brush that is less than 6 feet tall. However, this method is not suitable for taller, high-density brush. In such cases, high volume or aerial broadcast applications would be more effective.
When utilizing tank-mixes such as Arsenal AC + Method, it is important to ensure that the leaves are sprayed to the point of being wet, using a coarse droplet. The spray should be applied starting at the top of each stem of the brush, covering at least 70% of the leaves. This tank-mix is especially beneficial in areas where Loblolly or Virginia Pine are present alongside difficult to control hardwoods like hickory, red oak, red maple, yellow poplar, and sweet gum.
Visibility
Low-volume foliar applications is great for completing tasks discreetly, minimizing public visibility. The use of simple equipment and lack of noise allow for applications to take place without causing disruptions to homeowners.
Results
Utilizing low-volume foliar brush applications can significantly reduce brush density by more than 90%. This technique not only enhances productivity by 30% to 50% but also decreases herbicide usage by up to 50% when compared to high-volume applications.
