Recommended management methods: <br /> Cultural - Seeding and maintaining aggressive grasses will help in competing ' <br /> with Russian knapweed and slow its spread. Species such as thickspike <br /> wheatgrass and streambank wheatgrass have proven to be effective competition ' <br /> against Russian knapweed infestations. Proper grazing management will <br /> stimulate grass growth and keep pastures healthy. Healthy pastures may be <br /> more resistant to Russian knapweed invasion. Bare spots caused by overgrazing ' <br /> are prime habitat for weed infestations. <br /> Mechanical- Due to the extensive root system,hand-pulling this plant is not a <br /> viable option. Cutting several times before the plants bolt stresses Russian ' <br /> knapweed plants and forces them to use nutrient reserves stored in the root <br /> system. Combining mowing with herbicides will further enhance control of this <br /> weed. Mow repeatedly during the summer then apply a herbicide in the fall. <br /> Herbicides-The following are recommendations for herbicides that can be <br /> applied to range and pasturelands. A combination of seeding competitive grasses <br /> and the application of herbicides have proven to be effective in managing <br /> Russian knapweed. <br /> Always read,understand, and follow herbicide label directions. The herbicide ' <br /> label is the LAW! <br /> Clarity+2,4-D 1 qt./acre for each product Spring-bud to early flower stage and/or fall rosette stage.DO , <br /> Amine or NOT apply when outside temperatures will exceed 85 degrees. <br /> 1 oz/gal water for each Add non-ionic surfactant @ 0.32 oz/gal water or ' <br /> product 1 t/100 gal water. <br /> Curtail 3 qts./acre Spring-bud to early flower stage and/or fall rosette stage. <br /> or Add non-ionic surfactant @ 0.32 oz/gal water or <br /> 3.0 oz/gal water 1 t/100 gal water.
