Recommended management methods: ' <br /> Cultural- Establishment of selected, aggressive grasses can be an effective <br /> cultural control of cheatgrass. Contact your local CSU Extension office or Natural <br /> Resources Conservation Service office for seed mix recommendations. Good ' <br /> grazing management will stimulate grass growth and keep pastures healthy. <br /> Healthy pastures may be more resistant to cheatgrass invasion bare spots caused <br /> by overgrazing are prime habitat for weed infestations. , <br /> Mechanical- Fire, mowing, grazing, tillage,and inter-seeding competitive <br /> species have all shown promise in reducing cheatgrass populations. Long lasting <br /> control requires a combination of chemical, physical,vegetative suppression and , <br /> proper livestock management. <br /> Biological-Biological control is limited. Rabbits and mice will feed extensively <br /> on the seedlings as will migratory grasshoppers. But there is no long term <br /> biocontrol agent available. <br /> Herbicides-The following are recommendations for herbicides that can be <br /> applied to range and pasturelands. Always read, understand, and follow label <br /> directions. The herbicide label is the LAW! <br /> r <br /> Plateau 4 to 6 oz/acre Fall application prior to a hard freeze is optimum.Can also <br /> make application during early spring growth.Use a methylated ' <br /> seed oil surfactant(MSO)at 0.32 oz/gal water or 1 gt/100 gal <br /> water.The 12 oz rate of Plateau may cause injury to some cool <br /> season grasses.Can safely be used under trees. <br /> Panoramic 2 SL 4—8 Oz/Acre Apply pre-or post emergent in late summer or early fall.Use a ' <br /> MSO surfactant at 0.32 oz/gal or 1 gt/100gal water.The 12 oz <br /> rate of Panoramic 2SL may cause injury to some cool season <br /> asses.Can safely be used under trees. t <br /> *Roundup Ultra 16 to 24 oz/acre Apply in fall or early spring. <br /> *Non-selective Add a non-ionic surfactant @ 0.32oz/gal water or 1 gt/100 gal <br /> herbicide. OR water. <br /> other 41% Use caution when applying near grasses or other desirable <br /> concentrate vegetation.Roundup will possibly kill surrounding vegetation. <br /> Esplanade 200SC 5-7 oz/acre Non-crop areas.Can be tank mixed with Glyphosate or <br /> panoramic.Apply in August to March.Add a non-ionic <br /> surfactant 0.32oz/ al water or 1 t/100 gal water. <br /> Prowl H2O Short Term 2-4 months: A pre-emergent chemical—it will not kill established <br /> 2.1 quarts/acre growing plants. Spray solution may stain porous <br /> Long Term 6-8 months: surfaces Length of control is dependent on weather , <br /> 4.2 quarts/acre conditions. Not labeled for use in range and pasture <br /> settings. <br />
