Chaparral™ herbicide is the broadest-spectrum weed and brush control product available for rangeland and pastures. It is the simple answer for several significant, unique needs, such as reducing the impact of toxic fescue through seedhead suppression and improving hay quality by removing Pensacola bahiagrass from bermudagrass.
Chaparral™ herbicide helps increase overall forage production and utilization. As a fescue toxicosis management tool, Chaparral can help improve forage quality for improved cattle health and performance.
Chaparral delivers a more effective option for controlling buckbrush, other woody plants and broadleaf weeds and offers other features that make it a good choice for the land. With Chaparral, ranchers get a wide window of application on buckbrush; control of other shrubs and weeds often found in the same plant complex, such as absinth wormwood (wormwood sage) and Canada thistle; and a level of residual weed activity not available with other options for buckbrush control.
Chaparral controls many broadleaf weeds that other herbicides miss, including pigweed, hoarycress (whitetop), buckbrush, absinth wormwood (wormwood sage), Canada thistle, Missouri goldenrod, houndstongue, wild carrot, giant hogweed and many others.

Chaparral™ herbicide may be applied postemergence as a broadcast spray or as a spot application to control weeds and brush. Treat when weeds are actively growing and not stressed by drought or other conditions. Increase the herbicide rate within the labeled rate range as the season progresses and plants become more mature.
Aerial broadcast. Ground broadcast. Spot treatment. Apply the specified rate of Chaparral as a coarse low-pressure spray. Do not apply this product with mist blower systems that deliver very fine spray droplets. Spray volume should be sufficient to uniformly cover foliage. Increase spray volume to ensure thorough and uniform coverage when target vegetation is tall and/or dense.
Data shows that Chaparral controlled horsenettle at rates near 100 percent at the highest labeled rate.
Applications were made in the early summer, and plots were evaluated at three to five weeks after application.
By eliminating weeds and brush from range and pasture land, grass is given more of a chance to thrive, resulting in greater forage production.
Label precautions apply to forage treated with Chaparral or GrazonNext HL and to manure from animals that have consumed treated forage within the last three days. Consult the label for full details.
