Recommended management methods: , <br /> Cultural- After managing Russian olive infestations, other vegetation must be <br /> established to prevent re-invasion. Competitive grasses and planted cottonwood <br /> cuttings have proven to be effective at reducing the chances of re-invasion. ' <br /> Contact your local CSU Extension office or Natural Resources Conservation <br /> Service office for proper seed mix recommendations. <br /> Mechanical- In areas where woody native plants are present and their , <br /> continued existence is desired, or for large stands of Russian olive it may be <br /> necessary to cut and treat the stumps with a herbicide. This is referred to as the <br /> cut-stump treatment. Cuts should be made within 2 inches of the grounds ' <br /> surface, immediately followed by a herbicide application to the cut stems. The <br /> girdling method involves making shallow, overlapping cuts into the bark around <br /> the trunk base. Use a hatchet or chainsaw to make these cuts. Then lightly spray ' <br /> the entire cut surface with herbicide. <br /> Herbicides - For large stands of Russian olive that would essentially be , <br /> monotypic,foliar applications of herbicides are effective. Late summer/early fall <br /> are optimum treatment times using this method. This is recommended for areas <br /> that have little to no desirable shrubs and trees. <br /> Always read, understand, and follow herbicide label directions.
