Recommended management methods: Cultural -- After managing saltcedar infestations, other vegetation must be established to prevent re -invasion. Competetive grasses and planted cottonwood cuttings have proven to be effective at reducing the chances of re -invasion. Contact your local CSU Extension office or Natural Resources Conservation Service office for proper seed mix recommendations. Mechanical - A bulldozer or prescribed fire can be used to open up large stands of saltcedar. These methods must be followed up with a herbicide treatment of the resprouts when they are 1 to 2 meters tall. Herbicides - For large stands of saltcedar that would essentially be monotypic, foliar applications of the herbicide Arsenal, Habitat or Arsenal plus Roundup are effective. Late summer/early fall are optimum treatment times. This is recommended for areas that have little to no desirable shrubs and trees. In areas where woody native plants are present and their continued existence is desired, it may be necessary to cut and treat saltcedar stumps with a herbicide. This is referred to as the cut -stump treatment. Cuts should be made within 2 inches of the grounds surface, immediately followed by a herbicide application to the perimeters of the cut stems. The products Arsenal and Garlon are effective but must be applied within one minute after cutting because wound healing occurs very quickly and decreases herbicide penetration. Always read, understand, and follow herbicide label directions. The herbicide label is the LAW! Herbicide _ Rafe' _.:: .�.
