Monitoring of the property for the existence of any new noxious weeds and to determine <br /> the effectiveness of controls already applied is a very important aspect of weed <br /> management. Early detection and control of noxious weeds will save money and time in <br /> the long run. Throughout the growing season this property shall be carefully monitored <br /> for the start of any new noxious weed populations. The overall property shall be scouted <br /> at least once a year and examined for the start of any weed problems. it is up to the <br /> permit holder to become familiar with the weeds on the County and State noxious weed <br /> list. Contact the Routt County Weed Program with questions about weed species and <br /> suggested treatments. <br /> Specific Treatments <br /> All herbicide recommendations contained herein are for general management purposes <br /> only, and are in no way meant to replace or supersede any information contained on the <br /> herbicide label. Herbicide labels and recommended rates change, and an applicator must <br /> read the label to see if the following recommendations are still within labeled parameters. <br /> The herbicide label is the law and any deviation from the instructions on the label <br /> constitutes a violation of the law. <br /> White to (Cardaria draba) is also known as hoary cress. It is a perennial,producing by <br /> seeds and rhizomes. It does not respond well to mechanical means of control such as <br /> cutting, digging pulling or mowing. Like other aggressive, rhizomatous perennials <br /> herbicides offer the only long term control. The premier herbicides for control of <br /> whitetop are in the sulfonylurea group of herbicides and include Escort at 1.5 oz/acre or <br /> Telar at 1 oz/acre. The application needs to be made early in the season, preferably prior <br /> to full flowering, but absolutely before any fading of color is detected in the blossoms. <br /> In the spring,when plants are actively growing,it responds well to 3/4 oz. Escort+ 16 oz. <br /> 2,4-D amine per acre. Sixteen oz. of Banvel + 16 oz. 2,4-D amine per acre is less <br /> effective but still acceptable. Be sure and use a good quality surfactant with these mixes. <br /> The best treatment we have found is 1 oz. of Telar mixed with 32 oz. of MCPA, applied <br /> in 15-30 gal of water/acre in the spring just as blossoms form. <br /> 3 <br />
