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 /> Herbicide Rate Application Timing/Comments <br /> Plateau 4 to 6 oz/acre Fall application as a pre-emergent prior to a hard freeze is <br /> optimum for control.Use a methylated seed oil surfactant <br /> (MSO)at 0.32 oz/gal water or 1 qt/100 gal water.The 12 oz rate <br /> of Plateau may cause injury to some cool season grasses. <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 /> grasses. <br /> Laramie 25DF 4 oz/acre An early post-emergent option.Must be activated with rainfall <br /> and applied when soil temps are cool.Moisture must arrive <br /> within 2-3 weeks of application.Add a non-ionic or MSO <br /> surfactant 0.32oz/ al water or 1 t/100 gal water. <br /> Glyphosate 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 qt/100 gal <br /> herbicide.41% water.Use caution when applying near grasses or other <br /> concentrate min. desirable vegetation <br /> Rejuvra 5 oz/acre A pre-emergent chemical—it will not kill established growing <br /> plants.Can be tank mixed with Glyphosate,Panoramic 2SL or <br /> Plateau.Apply in August to March.Add a non-ionic surfactant <br /> 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 growing <br /> 2.1 quarts/acre plants.Can be tank mixed with Glyphosate,Panoramic 2SL or <br /> Long Term 6-8 months: Plateau.Spray solution may stain porous surfaces Length of <br /> 4.2 quarts/acre control is dependent on weather conditions.Not labeled for use <br /> in range and pasture settings. <br />
