Clearfield Wheat System

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. an adjuvant (nonionic sur-factant) and a liquid nitrogen fertilizer or ammonium sulfate solution is required.

Caution Apply to Clearfield wheat varieties only. Temporary height reduction or slight leaf yellowing may occur after application; effects can be more pronounced if the crop is under environmental stress. Do not tank mix with sulfonylurea herbicides (such as Finesse, Ally, or Harmony) due to potential crop response or weed-control antagonism. Apply Beyond a maximum of 2 out of 4 years. Do not plant Clearfield wheat continuously. There are no restrictions on feeding or grazing wheat forage and hay after applying Beyond. Some rotation crops cannot be planted within 26 months of application; see updated label for crop rotation restrictions.
