Recommended management methods: <br />Cultural - Establishment of selected, aggressive grasses can be an effective cultural <br />control of Dalmatian toadflax. Suggested species include: 'Hycrese crested wheatgrass, <br />'Luna' pubescent wheatgrass, 'Critana' thickspike wheatgrass, `Bozoisky' Russian <br />wildrye and 'Sodar' streambank wheatgrass. Good grazing management will stimulate <br />grass growth and keep pastures healthy. Healthy pastures may be more resistant to <br />Dalmatian toadflax invasion. Bare spots caused by overgrazing are prime habitat for <br />weed infestations. <br />Mechanical -- Hand -pulling this plant can be useful especially for small infestations in <br />sand and with wetter soils. Pulling must be repeated several times a year for up to 10 to <br />15 years to be sure the root stock and seed bank is depleted. Combining spring pulling <br />with fall use of herbicides will further enhance control of this weed. Mowing tends to <br />have little impact on reducing an infestation. Most mowed infestations continue to <br />spread and become more established. <br />Biological - Dalmatian toadflax is typically unpalatable to Iivestock. Several different <br />biological control agents are available. Contact the Colorado Department of Agriculture <br />Insectary in Palisade to learn more.

Always read, understand, and follow label directions. The <br />herbicide label is the LAW? <br />Heibiciae <br />Rate <br />Telar XP <br />2 to 2.5 ozjacre <br />Spring application is early flower stage or fall.
