Annual Grass and Broadleaf Weeds

Postemergence

imazamox (Beyond)

Clearfield wheat only

Rate 0.031 to 0.047 lb ai/a (4 to 6 oz/a Beyond)

Time Apply postemergence to Clearfield wheat, after tiller initiation but before jointing. In Clearfield Plus (2-gene) varieties, applications can be made from the 2-leaf stage (if nonionic surfactant is used) until the second joint is detected at the soil surface. May be applied in fall-winter or spring, for winter or spring annual weed control. Apply when most actively growing annual grass weeds are in the four- to five- leaf stage. Broadleaf weeds should be actively growing and less than 3 inches tall.

Remarks Adding a nonionic surfactant and a liquid nitrogen fertilizer or ammonium sulfate solution is required. For Clearfield Plus wheat varieties, crop oil concentrate or methylated seed oil may be substituted for nonionic surfactant after tiller initiation to increase weed control, but they may also increase crop response. Do not apply more than 8 oz/a per growing season.

Caution Use only on Clearfield wheat varieties. Temporary height reduction or slight leaf yellowing may occur after application; effects can be more pronounced under environmental stress. Do not tank mix with sulfonylurea herbicides due to potential crop response or weed control antagonism. Apply Beyond no more than 2 out of 4 years. Do not plant Clearfield wheat continually. There are no restrictions on feeding or grazing wheat forage and hay after applying Beyond. Some crops cannot be planted within 36 months of application. See label and supplemental label (Washington and selected counties in Idaho and Oregon) for crop rotation restrictions.

Site of action Group 2: acetolactate synthase (ALS) inhibitor

Chemical family Imidazolinone

pinoxaden + fluroxypyr (Axial Star)

Rate 0.053 lb ai/a (pinoxaden) + 0.094 lb ai/a (fluroxypyr) (16.4 oz/a Axial Star)

Time Apply to spring barley from the two-leaf to pre-boot stage. Apply to wild oat from one- to six- leaf stage on the main stem but before the fourth tiller emerges. Apply to green foxtail and Italian ryegrass from one- to five- leaf stage on the main stem but before third tiller emerges.

Remarks Use at least 5 gal/a water in aerial applications, 8 to 10 gal/a water in ground applications. Surfactant is not required with Axial Star formulation. REI 48 hours. PHI 60 days. Axial Star at 16.4 oz/a may be tank mixed with Starane herbicide (or other equivalent herbicides) at 2.7 oz/a (See label for Idaho, Oregon and Washington).

Caution Avoid applying in more than 10 gal/a water because grass control may be reduced. Do not apply to a crop stressed by conditions such as frost, low fertility, drought, flooding, or disease or insect damage, because crop may be injured.

Site of action Group 1: acetyl CoA carboxylase (ACCase) inhibitor + Group 4: synthetic auxin

Chemical family (pinoxaden) Phenylpyrazolin; (fluroxypyr) Pyridine

pyroxsulam (PowerFlex HL)

Rate 0.016 lb ai/a (2.0 oz/a PowerFlex HL)

Time Apply in either fall or spring to actively growing winter wheat from the three-leaf to jointing stage and after most weeds have emerged.

Remarks Apply with a nonionic surfactant (0.25% to 0.50% v/v) and ammonium sulfate (1.5 lb/a). When applying with fluid fertilizer, spray solution should not be composed of more than 50% liquid nitrogen and should not exceed 30 lb of actual nitrogen per acre. If applying with liquid nitrogen, use a nonionic surfactant at a maximum of 0.25% v/v, instead of crop oil concentrate.

Caution For winter wheat only. Do not mix with products containing dicamba or amine formulations of 2,4-D or MCPA or organophosphate insecticides. Consult label for crop rotation restrictions.

Site of action Group 2: acetolactate synthase (ALS) inhibitor

Chemical family Triazolopyrimidine sulfonamide

pyroxsulam (TeamMate)

Rate 0.0133 lb ai/a (1.0 oz/a TeamMate)

Time Apply to actively growing wheat from the three-leaf to jointing stage and after most weeds have emerged.

Remarks Apply with a nonionic surfactant (0.25% to 0.50% v/v) and ammonium sulfate (1.5 lb/a). Warm, moist growing conditions promote active weed growth and enhance activity of TeamMate. Weeds hardened off by cold weather or drought may not be adequately controlled or suppressed and may regrow.

Caution Do not apply more than 1.0 oz/a per growing season. Do not apply within 60 days of harvest.

Site of action Group 2: acetolactate synthase (ALS) inhibitor

Chemical family Triazolopyrimidine sulfonamide

pyroxsulam + florasulam + fluroxypyr (GoldSky)

Rate 0.10 lb ai/a (16 oz/a GoldSky)

Time Apply to actively growing wheat from 3-leaf to jointing stage after most weeds have emerged.

Remarks Apply with a nonionic surfactant (0.25 to 0.5% v/v) and ammonium sulfate (1.5 lb/a). Apply postemergence to the main flush of actively growing weeds according to target weed stage on label.

Caution Do not use with dicamba or amine formulations of 2,4-D or MCPA. Do not use an adjuvant when applying GoldSky in combination with emulsifiable (EC) formulations such as 2,4-D ester or MCPA ester products. Do not tank mix with organophosphate insecticides.

Site of action Group 2: acetolactate synthase (ALS) inhibitor and Group 4: synthetic auxin

Chemical family (pyroxsulam) Triazolopyrimidine sulfonamide; (florasulam) Sulfonanalide; (fluroxypyr) Pyridine

pyroxsulam + fluroxypyr + clopyralid (PerfectMatch)

Rate 0.013 lb ai/a pyroxsulam + 0.097 lb ae/a fluroxypyr + 0.097 lb ae/a clopyralid (1 pint/a PerfectMatch)

Time Apply to actively growing wheat from 3-leaf to jointing stage. Treat after most weeds have emerged.

Remarks Apply with a nonionic surfactant (0.25 to 0.5% v/v) and ammonium sulfate (1.5 lb/a). PerfectMatch works best when weeds are actively growing and not hardened off by cold weather or drought. PerfectMatch is rainfast within 4 hours after application.

Caution Do not apply more than 1 pint/a per growing season. Limit nonionic surfactant rate to 0.25% v/v when tank mixing with up to 6 fluid oz/a of EC formulated product per acre. Do not use any surfactant when total EC products exceed 6 fluid oz/a. Do not apply within 60 days of harvest.
