Weed Control



  • Choke out desirable forage for livestock and wildlife.
  • Reduce the productivity of your pasture.
  • Poison your animals.
  • Spread RAPIDLY!

Weeds in small pastures can significantly reduce available forage. Most weed problems can be prevented with good grazing, fertilization and irrigation practices, but continually watch for new weed invasions. Among the most common broad-leaf weeds in pastures are burdock, cocklebur, whitetop, curly dock, teasel and thistles. Foxtail barley is one of the most troublesome grassy weeds. Weed identification is the first step toward and effective control program.

  • A shovel can be used to dig out widley scattered weeds. Clipping weeds before they go to seed will help prevent existing problems from getting worse. When using herbicides, remember that most weeds are better controlled when they are small. Owners of small pastures will generally need to use products based on 2,4-D or dicamba (Banvel) for braodleaf weeks and glyphosate (Roundup) for spot treatment of grassy weeds.
  • Keep in mind that Roundup is non-selective and will kill desirable plants as well.
  • Always read herbicide labels carefully and follow directions. Animals may need to be removed for a number of days after spraying.
  • For best resutls team up with your neighbors in a joint control effort so weekds are less likely to return from across the fence.
