Russian Knapweed <br />A. Cultural and Chemical Control - An herbicide application, using short <br />residual herbicides will be used followed up by seeding the azea with a <br />competitive grass such as western wheatgrass or other sod forming species <br />(indicate species). <br />B. Mechanical and Chemical Control -Mowing will be tamed out throughout <br />the season with the first and successive mowing cycles carried out at the bud <br />stage. A herbicide treatment will be made in the fall before a hazd freeze. <br />C. Mechanical Control On1v - Multiple mowings will be carried out throughout <br />the season to prevent seed set. ('This is the least effective option.) <br />D. Chemical Control Only - A herbicide will be used in the spring from bolting <br />to bud stage and in the fall, if necessary. The same herbicides listed above for <br />Canada thistle can be used on Russian larapweed. <br />Diffuse and Spotted Knapweed <br />A.. Cultural and Chemical Control -Apply herbicide in eazly summer when the <br />knapweed is in the rosette up through bolt stage. Re-seed azea with <br />competitive perennial sod forming grass (indicate species) Another herbicide <br />application will be applied the following year as needed to prevent plants from <br />going to seed. <br />B. Mechanical and Chemical Control -During the growing season, multiple <br />mowings of the knapweed, no later than the bud stage to prevent seeding. An <br />application of a herbicide to any plants that have re-bolted will be made in the <br />fall before a hard frost. <br />C. Mechanical Control Only -Multiple mowings will be carried out throughout <br />the season to prevent seed set. <br />D. Chemical Control Only - An herbicide application will be made during the <br />rosette stage (spring and fall) and while bolting: The herbicides that can be <br />used independently or in combination with other herbicides on diffuse and <br />spotted knapweed include: Curtail, Redeem R & P, Clarity, Telaz, Roundup <br />Pro, and 2,4-D. You must read the label and use a herbicide labeled for the <br />intended site. <br />Leafy Spurge <br />A. Biolo¢ical and Chemical Control - A combination of grazing with sheep or <br />goats; or the release of one of the Apthona flea beetle species will occur <br />during the spring and summer. This will be followed up by the application of <br />a herbicide in the fall before a hazd freeze. <br />B. Mechanical and Chemical Control -Multiple mowings will be carried out <br />throughout the growing season with the first mowing cycle at the bud, stage. <br />Mowing will stop during late August followed by a herbicide treatment during <br />late September or early October (before a hazd freeze). <br />C. Chemical Control Only - A herbicide will be used in the spring, eazly summer <br />during the true flower stage and in the fall just before a hazd freeze, if <br />necessary. The herbicides that can be used independently or in combination <br />with other herbicides on leafy spurge include: Clarity, Tordon 22K, Plateau, <br />
