Keeping weeds out of the way of your pasture production during the summer months delivers the benefits you need to maximize your lowest-cost feed source — your grass.

No matter how you put it to work on your ranch, you can’t go wrong growing more grass. Consider the options and bottom-line benefits that healthy, productive pastures present:

  • Increase stocking rates and produce more beef per acre — at a lower cost
  • Extend the grazing season and delay the expensive hay-feeding season
  • Stockpile more standing or harvested forage
  • Gain flexibility in your grazing program and enhance the long-term health of your land


Unless marred by drought, summer can be a valuable time to target many troublesome broadleaf weeds, along with other later-emerging ones, such as ragweed, pigweed and goldenrod.

Target rangeland threats such as houndstongue, ironweed, common tansy, hawkweeds and knapweeds when they are emerged and actively growing to ensure maximum herbicide uptake and root translocation. The same goes for tough pasture weeds, including Canada thistle, pigweed and cocklebur.

As a rule, make DuraCor® herbicide your first choice for most situations. DuraCor controls more than 140 broadleaf weeds at multiple growth stages. You get preemergence and postemergence control — soil residual activity to stop new flushes of weeds for weeks after application — giving you longer-lasting control than either 2,4-D or dicamba.

If a nonresidual option better meets your needs, choose PastureGard® HL herbicide. In addition to providing the best control of sericea lespedeza available, PastureGard HL controls many other weeds and woody plants.
