grasses. (The local County Extension Agent can help develop any mixes in the future.) Treatment of noxious weeds varies by the severity of the infestation, the biology of the plant, location, time, and money. Biological, chemical, mechanical, and cultural controls are all important, and to maximize control it is best if more than one method is employed on each weed infestation. Specific treatments are outlined below. Monitoring of the property for the existence of any new noxious weeds and to determine the effectiveness of controls already applied is a very important aspect of weed management. Early detection and control of noxious weeds will save money and time in the long run. Throughout the growing season this property shall be carefully monitored for the start of any new noxious weed populations. The overall property shall be scouted at least once a year and examined for the start of any weed problems. It is up to the permit holder to become familiar with the weeds on the State noxious weed list. Contact the Colorado State University Extension Office in Otero County with questions about weed species and suggested treatments.
