Brush control brings lasting benefits

High-volume foliar (leaf-spray) applications with PastureGard® HL herbicide give you the pasture maintenance tool you need to easily and economically target smaller, less dense encroaching brush before it becomes a larger and more expensive headache. And summer is the time to get the job done.

High-volume foliar (leaf-spray) applications give you the pasture maintenance tool you need to easily and economically target smaller, less dense encroaching brush before it becomes a larger and more expensive headache. And, summer is the time to get the job done.

Focus your efforts along fence lines and then on scattered saplings of species, such as honeylocust and hedge (Osage orange), and multistemmed plants like multiflora rose.

Recipe for success

Prepare a mix that is 1 percent PastureGard® HL herbicide in  water. (Table 1 provides mixing ratios for common sprayer sizes.) Using a hand wand and equipment you likely already own, such as ATV-mounted units or larger tractor-powered sprayers, simply spray the leaves of target plants until thoroughly wet, but not dripping.

This mix provides broad-spectrum control of many woody plants, including hedge (bois d’arc), rose, locust, and sumac and broadleaf weeds. And, it won’t harm desirable grasses. When certain species are present, such as Russian or autumn olive, or to broaden the broadleaf weed control spectrum, consider tank-mixing GrazonNext® HL and Remedy® Ultra herbicides (see Table 2).

Broadcast options

For widespread (more than 150 plants per acre) woody sprouts or saplings, broadcast applications are the most efficient way to go.

Ground rigs equipped with booms or boomless nozzles work well, as long as target brush is small enough for adequate coverage (shorter than 10 feet for boomless rigs or short enough for fixed booms to pass over).


Broadcast up to 2 quarts of PastureGard HL per acre for most woody plants and broadleaf weeds. For broader-spectrum control, along with residual weed control, apply 1 quart of GrazonNext HL plus 1 to 2 pints of Remedy Ultra per acre. Include a quality agricultural surfactant and a drift agent and apply 15 to 25 gallons of total spray volume per acre to help ensure adequate coverage and more consistent results.

Renovating mature brush stands requires aerial applications. These projects also require persistence, patience and often a multi-year commitment to kill the extensive root systems that will continue to send up new growth beyond the initial herbicide application. Work closely with your aerial applicator or Range & Pasture Specialist with Corteva Agriscience™. These experts can help inventory species present and develop a prescription program for reclaiming land lost to brush.
