Superior Site Prep And Mid-Rotation Release

For years, landowners, consultants and applicators have gotten industry-leading performance from Chopper® herbicide. Now, you can upgrade to something even better: Chopper GEN2. Utilizing Transport Technology, a BASF exclusive, Chopper GEN2 allows more of the active ingredient to get into the plant without decreasing control. This means Chopper GEN2 delivers the same superior, long-term control of unwanted grasses, weeds, vines and hardwoods you expect, but at a lower cost per acre.

Application Information

Perfect For Site Prep

Reports show herbicides deliver site preparation that's 60% the cost of intensive mechanical methods.1 And the powerful chemistry of Chopper GEN2 with Transport Technology improves upon those herbicides reported, accelerating protein blockage in targeted species, leading to faster, more consistent control up front and more effective long-term control.

Right For Mid-Rotation Release

Release treatments are especially important on land that didn't receive proper site preparation, an early release treatment or on thinned sites with re-invading hardwoods. An understory mid-rotation release treatment with Chopper GEN2 helps eliminate hardwood brush and allows established pines access to more nutrients, root space and sunlight, which in turn improves long-term growth rates. Based on one economic projection, mid-rotation release on a 10-year-old pine stand provided a real annual rate of return of 11.2 percent in 15 years.2 In addition, studies also show improved release of wildlife-preferred forage with Chopper GEN2.

More Chopper GEN2 Benefits

Chopper GEN2 is more rainfast than any other similar herbicide in the industry. In addition, Chopper GEN2 can be applied from full leaf-out in spring – when applicators and equipment are most readily available – all the way through leaf-drop in the fall.* Studies show Chopper GEN2 can help improve wildlife habitat and biodiversity, too. When sunlight is able to reach the forest floor, wildlife-preferred food sources like blackberry, forbs and legumes flourish. Chopper GEN2, which binds with an enzyme found only in plants (not in people, mammals, birds, fish or insects), helps promote the growth and re-colonization of the desirable, native plants that provide forage and enhance wildlife habitat.

Key Weeds Controlled

Because Chopper GEN2 is a low-volume herbicide, it helps manage public concerns and wildlife habitat as well. It's effective against problem species such as:

sweet gum
yellow poplar
Bahia grass
cogon grass
Johnson grass
Russian thistle

A complete list of weeds controlled can be found on the Chopper GEN2 product label. Always read and follow label directions.
