The purpose of this letter is to bring to <br /> your attention the need for control of weeds on these areas. <br /> The infestations of concern are musk thistle(Carduus nutans ), tall whitetop(Lepidium Iatifolium), <br /> and Canada thistle (Cirsium anmse ). I have consulted with Cindy Owsley, Boulder County Weed <br /> Coordinator, and she has recommended that these infestations be treated with Telar herbicide. For these <br /> species, the label calls for a rate of 1 '/ to 3 oz. per acre. This treatment is effective on all of these <br /> species. Control should be timed to prevent production of viable seed. Treatment before June 15 will <br /> probably be effective, however this may vary with weather conditions. <br /> I appreciate your attention to this matter and I would be happy to offer further assistance it making <br /> sure these infestations are properly addressed. <br /> Since ,Al�/ �• <br /> Rob Alexander <br /> Agricultural Resources <br /> RA/Im <br /> Jana L.Mendez Ronald K.Stewart Paul Danish <br /> County Commlssloner County Commlssloner County Commissioner <br />
