Brush Control Season Begins: Buckbrush

While it can grow to over 6′, buckbrush seldom reaches more than 3-4′ in pastures. It’s shorter stature plus the fact it’s one of the first brush species to get going in spring can catch us off guard, and before we know it we’re past its optimum control window – and that window is now!

Herbicide options include products containing 2,4-D or 2,4-D plus aminopyralid or picloram (restricted use). Timing is important. Make application after full leaf but before leaves form a waxy cuticle as they turn from a lighter to a darker green shade. While tempting to wait for other species to ‘catch up’ for one pass control, herbicide efficacy can be compromised if plants get too well established. Multiple herbicide passes will likely be required.

An integrated approach can be of longer-term value with options including:

• livestock – goats are better than cattle
• prescribed fire – can be of value in warm season stands if burned for 2-3 consecutive years; could be tough in cool season stands
• mowing – a single mowing may only encourage resprouting, with multiple mowing passes required to make a dent in the stand.
• removal of root systems – newly established plants are relatively easy to pull out and can be an option if stands are small.

Buckbrush isn’t likely a one pass control species. Early spring is our best opportunity for control and this species deserves attention sooner than later.

When applying herbicides, always read and follow label directions.
