Tough Broadleaf Weeds

Chaparral herbicide controls some of the most troublesome broadleaf weed and brush species, and it does so with many other features that make it the right choice for your operation.

  • Provides control of many broadleaf weeds that other herbicides miss, including pigweed, hoarycress (whitetop), buckbrush, absinth wormwood (wormwood sage), biennial thistles (including bolted musk thistle), Missouri goldenrod, wild carrot, giant hogweed and many others
  • Soil residual activity controls new weeds that can emerge in multiple flushes throughout the grazing season
  • Effective at suppressing fescue seed heads to help mitigate issues arising from fescue toxicosis
  • No license required to buy or apply Chaparral1
  • Does not contain 2,4-D
  • No grazing or haying restrictions for any class of livestock, including lactating dairy cows, horses (including lactating mares) and meat animals prior to slaughter
  • Low use rate — 1.5 to 3.3 ounces per acre

Buckbrush Control

Chaparral herbicide 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.

  • Provides a level of residual weed activity not available with other options for buckbrush control
  • Controls other shrubs, absinth wormwood (wormwood sage) and Canada thistle, which often grow in the same complex with buckbrush
  • A wide application window allows treatment on your schedule
  • Low use rate for buckbrush — 3.3 ounces per acre
  • Controls many tough-to-control broadleaf weeds, including common mullein, Canada thistle, curlycup gumweed, absinth wormwood, Missouri goldenrod, hoary cress (whitetop), common tansy, snow-on-the-mountain, biennial thistles (including bolted musk thistle), houndstongue, ragweeds, wild carrot, giant hogweed and many others
  • No license required to buy or apply Chaparral1
  • No grazing or haying restrictions for any class of livestock, including lactating dairy cows, horses (including lactating mares) and meat animals prior to slaughter

Fescue Seedhead Suppression

A New Way to Mitigate Fescue Toxicity

Mitigate_Fescue_Toxicity_videothumbnail

 

 

 

 

 

 

 

If you run cattle in the fescue belt, there’s a good chance fescue toxicosis is harming your herd. Researchers estimate 85 percent of the 40 million acres of tall fescue in the United States (mostly the variety Kentucky 31) contains endophyte-infected fungus that causes poor performance and health problems in our beef herds.

U.S. Department of Agriculture Agricultural Research Service scientists estimate almost 1 in 5 (17.2 percent) of all cows and heifers in the United States in 2009 were exposed to toxic endophyte-infected fescue. Endophyte-infected fescue limits grazing livestock performance on several fronts, including:

  • Elevated body temperatures
  • Reduced feed intake and weight gains
  • Poorer conception rates and lower calving percentages
  • Reduced milk production and lower weaning weights
  • Other health issues, including lost hooves and docked tails

Researchers peg the annual financial hit to the cattle industry at $1 billion — $338 million of that comes from reduced weaning weights in the cow-calf sector.

Given today’s cattle economics, producing low-cost pounds of gain is more important than ever. It’s easy to understand why tall fescue management strategies warrant your attention. This video discusses seedhead suppression — a new approach developed by Dow AgroSciences to help mitigate fescue’s toxic impact. The seedhead suppression information under Related Downloads on this page provide additional detail.


Remove Pensacola Bahiagrass From Bermudagrass

Superior control of Pensacola bahiagrass, along with its unique features help make Chaparral herbicide the right choice for high-quality bermudagrass production.

  • Controls Pensacola bahiagrass, plus a wide spectrum of other broadleaf weeds, including broomweed, annual ragweeds, bitter sneezeweed, woolly croton, thistles, horsenettle, nightshades, wild carrot and many others
  • Safe for use on common and improved varieties of bermudagrass
  • Residual activity controls broadleaf weeds that emerge weeks after application
  • Does not contain 2,4-D
  • There are no grazing or haying restrictions for any class of livestock, including lactating dairy cows, horses (including lactating mares) and meat animals prior to slaughter
  • Low use rate for Pensacola bahiagrass — 2 to 2.5 ounces per acre
