Treatment of noxious weeds varies by the severity of the infestation, the biology of the <br />plant, location, time, and money. Biological, chemical, mechanical, and cultural controls <br />are all important, and to maximize control it is best if more than one method is employed <br />on each weed infestation. Specific treatments are outlined below. <br />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 them to see if the following recommendations remain within labeled parameters. <br />The herbicide label is the law and any deviation from the instructions on the label is a <br />violation of the law. <br />White top (Cardaria drabs) is also known as hoary cress. It is a perennial, producing by <br />seeds and roots. It does not respond well to any control other than spraying. The premier <br />herbicides for control of whitetop are in the snlfonylurea group of herbicides and include <br />Escort at 1.5 oziacre or Telar at 1 ozracre. The application needs to be made early in the <br />season, preferably prior to full flowering, but absolutely before any fading of color is <br />detected in the blossoms. In the spring, when plants are actively growing, it responds <br />well to loz. Escort + 32 oz. 2,4-D amine per acre. Sixteen oz. of Banvel + 32 oz. 2,4-D <br />amine per acre is less effective but still acceptable. Be sure and use a good quality <br />surfactant with these mixes. Though not observed on 10/13/15 its occurrence is <br />somewhat likely, because of site location, and should be monitored in May of 2016 to <br />confirm its absence or presence. <br />3 <br />
