Recommended management methods: <br /> Cultural- Establishment of selected, aggressive grasses can be an effective cultural <br /> control of hoary cress. Contact your local CSU Extension office or Natural Resources <br /> Conservation Service office for seed mix recommendations. Good grazing management <br /> will stimulate grass growth and keep pastures healthy. Healthy pastures may be more <br /> resistant to hoary cress invasion. Bare spots caused by overgrazing are prime habitat for <br /> weed infestations. <br /> Mechanical- Due to the extensive root system,hand-pulling this plant is not a viable <br /> option. Repeated tillage (every 10 to 14 days)can destroy colonies in 2 to 4 years. <br /> Combining mowing with herbicides will further enhance control of this weed. Apply <br /> herbicides in spring and/or fall,and then mow during the summer months. Mowing <br /> alone is not an effective control option. <br /> Biological No known biological control agents available at this time. <br /> Herbicides- The following are recommendations for herbicides that can be applied to <br /> range and pasturelands. Always read, understand, and follow label directions. The <br /> herbicide label is the LAW! <br /> Herbicide Rate Application Timing/Comments <br /> Escort XP Ito 2 oz/acre Apply from bud to early bloom stage or at fall rosette.Add a <br /> or non-acidifying non-ionic or MSO surfactant @ 0.32oz/gal water !. <br /> 1.3 grams to 3 gallons of water or lac t/10o gal water. <br /> Telar XP 0.5 to 1 oz/acre !
