Tarweed (Madia glomerata) is a broadleaf annual. They can be controlled by either <br />using Round-up, where grass loss can be tolerated, or disked before flowering. Because <br />tarweed is an annual and prevention of seed production is the primary goal, an <br />application of 2 qts/acre of 2,4-D 4 lb amine can effectively dessicate the weed and <br />prevent seed maturity. Tarweed can be controlled with Escort at 3/4 oz per acre with a <br />good surfactant. This weed will typically disappear once good grass cover is established. <br />Common mullein (Verbascum Thapsus) Is a broadleaf biennial with prolific seed <br />production potential and extreme seed longevity. It is relatively difficult to control with <br />herbicides, but responds well to Perspective at 5-7 oz. / ac, When using Perspective near <br />trees .or desirable shrubs care must be taken to avoid the root zone. Removal of flowering <br />stalks and bagging and disposing of them is a good technique for preventing new seed <br />populations. Spraying should be done on 1St or 2nd year rosettes with sufficient water <br />volume and a good surfactant to ensure herbicide penetration. <br />Other Noxious Weeds not listed here: Glyphosate (Roundup) is often, but not always <br />effective when treating individual plants or when loss of grass is not a problem. The <br />Routs County Weed Supervisor will work with the permit holder to develop specific <br />control measures needed to control any noxious weeds found in the future on this <br />property but not described here. <br />6 <br />
