healthy pasture and rangeland and continually monitor your property for new <br />infestations. <br />Below are yellow toadflax management recommendations. If you have any <br />questions, please contact the Weld County Public Works Dept., Weed Division at <br />(970) 304-6496 ext. 3770. Please visit our website at www.weldweeds.org <br />Recommended management methods: <br />Cultural - Establishment of selected, aggressive grasses can be an effective cultural <br />control of yellow toadflax. Contact your local CSU Extension office or Natural <br />Resources Conservation Service office for seed mix recommendations. Good grazing <br />management will stimulate grass growth and keep pastures healthy. Healthy <br />pastures may be more resistant to yellow toadflax invasion. Bare spots caused by <br />overgrazing are prime habitat for weed infestations. <br />Mechanical -- Hand -pulling this plant can be useful especially for small infestations <br />in sand or with wetter soils. Pulling must be repeated several times a year for up to <br />10 to 15 years to be sure the root stock and seed bank is depleted. Mowing is not <br />recommended as it stimulates more plants to grow from the roots. Mowing <br />combined with herbicide application does not improve control. <br />Biological - There are several different biological control agents being used, but the <br />success of the agents is yet to be determined. Contact the Colorado Department of <br />Agriculture Insectary in Palisade to Iearn more. Please call 970-464-7916 or go to <br />www.palisadeinsectaiy.com for detailed information. <br />Herbicides - The following are recommendations for herbicides that can be applied <br />to range and pasturelands. Testing of additional chemical options is on going. <br />Always read, understand, and follow label directions. The herbicide label is the <br />LAW! <br />Herbicide <br />Rare <br />.—. ._ <br />Plateau <br />8 oz/acre <br />Fall application prior to a hard freeze is optimum. Can also <br />or <br />make application during early flower stage. Add a methylated <br />0A ovgal <br />seed oil surfactant (MSO) at 0.32 oz/gal water or 1 qt/100 gal <br />water. 12 oz rate may cause injury to some cool season grasses. <br />Can safely be used under trees. <br />Tordon 22K <br />1 qt./acre <br />Apply at flowering for several consecutive years.
