Achieve (tralkoxydim):

Achieve is labeled for control of wild oats and other annual grass weeds in barley. Due to crop injury potential, Achieve is NO LONGER labeled for use in spring wheat and durum in Minnesota.

Apply Achieve to barley in the 2 to 6-leaf stage. Apply Achieve to 1 to 6-leaf wild oat. Achieve use rate is 0.44 to .60 lb/A. Use the high rate when soil is dry and weeds are large. Apply Achieve in at least 10 gpa by ground or 5 gpa by air. Always add Supercharge adjuvant to the spray solution at 4 pts/100 gals of water (0.5% v/v). Ammonium sulfate at 15 lbs/100 gals of water can also be added.

Numerous broadleaf herbicides can be tank-mixed with Achieve. Achieve can be tank-mixed with MCPA ester, Bronate, Buctil, Curtail M, and Stinger. Achieve can be tank mixed with 2, 4-D ester when ammonium surfactant is added. DO NOT tank mix with amine formulations of labeled herbicides. DO NOT tank mix with sulfonylurea herbicides.

Achieve can cause barley injury under cool, wet conditions. DO NOT apply Achieve to barley that has a heavy dew.

Assert (imazethabenz):

Assert is labeled for wild oat control in spring wheat, durum, and barley. Assert will also control some plants in the mustard family, including wild mustard. Spring wheat, durum and barley have good tolerance to Assert.

The use rate of Assert is 1.0 to 1.2 pts/A. For best control, apply Assert when wild oats are in the 1 to 4-leaf stage. Good wild oat control has been obtained when the 1.0 pt/A rates have been applied to 1 to 3-leaf wild oats; however, for larger wild oats, the 1.2 pt/A rate should be used. Assert must always be applied with a non-ionic surfactant at a rate of 2 pts of surfactant per 100 gallons of spray solution. For control under adverse conditions, such as dry conditions or heavy wild oat pressure, Assert should be applied with a crop oil concentrate at 2 pt/A in addition to the surfactant. Do Not apply crop oil concentrate with 2,4-D ester because of the potential for crop injury.

Assert can be tank mixed with 2,4-D ester, MCPA ester, Bronate Advance (bromoxynil + MCPA ester), Harmony Extra (tribenuron + thifensulfuron) and Harmony GT. Do not tank mix with Banvel (dicamba), MCPA amine, or 2,4-D amine as reduced wild oat control will result.

Assert has soil activity, and may persist for more than one year in the soil; therefore, do not plant any crop other than barley, wheat, corn, sunflowers, soybeans or edible beans for at least 15 months after an Assert application. Do not plant sugarbeets for at least 20 months following an Assert application. Do Not plant oats, canola, or alfalfa for 15 months after an Assert application.

Discover (clodinafop):

Discover is labeled for postemergence control of wild oat and other annual grass weed control in spring wheat and durum. Discover is NOT labeled for use in barley and winter wheat. Apply Discover from the 2 leaf-stage until the emergence of the 4th tiller of spring wheat and durum. Apply when wild oats are in the 1 to 6-leaf stage and foxtails are in the 1 – 5-leaf stage

Discover is sold in a case that contains the herbicide and DSV adjuvant packaged in separate containers and treats 40 to 50 acres depending on the use rate. Discover must always be applied with the DSV adjuvant. DO NOT add any additional adjuvants. Apply Discover at 3.2 fl oz/A plus DSV adjuvant at 10.2 fl oz/A (treats 50 acres) for wild oat control. Apply Discover at 4.0 fl oz/A plus DSV adjuvant at 12.8 fl oz/A for green and yellow foxtail control.

In 2004, Discover will be sold in two different formulations – Discover and Discover NG. The Discover NG formulation has an adjuvant in the formulation. Do Not add any additional adjuvant. Use rate of Discover NG is 12.8 to 16 oz/A. Apply Discover NG at 12.8 oz/A for wild oat and 16 oz/A for green and yellow foxtail control.

Discover/Discover NG can be tank-mixed with most broadleaf herbicides for green foxtail and wild oat control. However, always follow the label of the tank-mix broadleaf herbicide. For green foxtail and wild oat control, Discover/Discover NG can be tank-mixed with Starane, Starane+Sword, Bronate, Bronate Advance, Buctril, Curtail, Curtail M, Harmony Extra, Harmony GT, Harmony GT + MCPA, 2,4-D amine, MCPA amine and ester, Stinger, Curtail, Banvel, and Clarity. Apply Discover/Discover NG in a minimum spray volume of 5 gpa by ground and 3 gpa by air. For yellow foxtail control, Discover/Discover NG can be tank-mixed with Bronate Advance, Buctril, and Harmony GT.

Wheat injury can occur when air temperatures are below 40 F during the period 48 hours before and after a Discover/Discover NG application. Do not graze livestock or feed forage or hay from treated areas for a minimum of 30 days following a Discover application. Do not apply Discover/Discover NG within 60 days of harvest.

University of Minnesota research has shown that spring wheat and durum tolerance to Discover/ Discover NG is good to excellent. Discover/Discover NG has resulted in good to excellent wild oat and foxtail control in research plots.

Everest (flucarbazone):

Everest is labeled for wild oat control and suppression of foxtails in spring wheat and durum. Everest is NOT labeled for use in barley. Apply Everest from the 1 to 4-leaf stage of spring wheat and durum. Apply when wild oats are in the 1 to 6-leaf stage. The use rate of Everest is 0.61 oz/A for wild oat control. Apply when green and yellow foxtail are in the 1 to 4-leaf stage. The use rate of Everest is 0.41 oz/A for green foxtail control and 0.61 oz/A for yellow foxtail suppression. Spring wheat and durum tolerance is fair to good. For optimum wild oat control and crop safety, Everest must be tank-mixed with a surfactant and a broadleaf herbicide listed on the label. Apply a non-ionic surfactant at 1 qt/100 gallon or 0.25% v/v. Always tank-mix Everest with 2,4-D amine or ester, Buctril, Bronate Advance, Curtail, Curtail M, Aim, Harmony Extra + 2,4-D amine or ester, Harmony GT + 2,4-D amine or ester, or MCPA amine. See label for rates and tank-mixing instructions. Do NOT tank-mix Everest with any broadleaf herbicide not list on the label.

Everest has soil activity and recropping restrictions. Sugarbeets, barley, canola, and potatoes should not be planted until 9 months after application. Field peas can be planted 11 months after application. See label for additional recropping restrictions.

University of Minnesota research has shown that Everest will provide good wild oat control, fair control of green foxtail and suppression of yellow foxtails. Everest can cause wheat injury under adverse weather conditions.

Puma (fenoxaprop + safener):

Puma is labeled for control of wild oats and other annual grasses in spring wheat, durum, and barley. Crop tolerance to Puma is good to excellent, with spring wheat having greater tolerance than durum or barley. Apply Puma to wheat from emergence to 6-leaf stage. Apply Puma to barley from emergence to the 4-leaf stage. For greatest crop safety – do not apply to wheat after jointing. Puma will control susceptible grass weeds in the 2-leaf to 2-tiller stage. Puma use rate is 0.33 to 0.67 pt/A. Puma at 0.33 pt/A controls green foxtail, foxtail millets, and volunteer corn, at 0.4 pt/A controls yellow foxtail and proso millet, at 0.67 pt/A controls wild oat and barnyardgrass.. Apply Puma in at least 10 gpa by ground and 5 gpa by air. Puma can be tank-mixed with numerous broadleaf herbicides, but it is important to follow label restrictions to avoid a reduction in grass control. For control of wild oat, Puma at 0.67 pt/A can be tank mixed with Buctril, Bronate, Bronate Advance, Curtail M, Stinger, Starane, MCPA ester, Harmony Extra, Harmony GT, Peak, and Tordon. Puma can also be tank-mixed with Furadan, Sevin XLR Plus, Mancozeb, Tilt, or Benalate. DO NOT apply Puma to corn, tame oats, or rye. Do NOT apply Puma within 60 days of wheat harvest or 57 days of barley harvest. Research at the University of Minnesota has shown that Puma will provide good to excellent control of wild oats and foxtails with good crop safety.

Silverado (mesosulferon + safener):

Silverado received a label for the control of wild oats in spring wheat in 2004. Do NOT apply Silverado to durum or barley. Silverado is a ALS inhibitor herbicides and will be useful in the control of and the future preventation of ACCase resistant wild oats. Apply Silverado to spring wheat from crop emergence to jointing. Apply to wild oats in the 1–leaf to 2-tiller stage at 1.57 to 2.25 oz/A. Silverado must always be applied with a methylated seed oil or a basic blend adjuvant. See label for details. Silverado can be tank mixed with Buctril, Bronate Advance, Ally Extra, Curtail M, Express, Harmony Extra, Harmony GT, MCPA ester, Starane and Stinger. See label for rates and tank-mixing instructions. Do NOT tank-mix Silverdo with any broadleaf herbicide not listed on the label. Silverado has soil activity and recropping restrictions. Sugarbeets, canola, and potatoes should not be planted until 10 months after application. Corn can be planted 12 months after application. See label for additional recropping restrictions. Silverado can cause spring wheat injury under adverse weather conditions, however, this injury as not caused a yield loss in University of Minnesota research trials. Crop tolerance to Silverado is fair to good.
