THE NEW herbicide Rimfire will fight many grass and broadleaf weeds in spring wheat fields. Bayer CropScience recently received EPA registration for the postemergent use of Rimfire in Northern Plains wheat fields. The targeted areas include Minnesota, North Dakota, South Dakota and Montana. Through contact and residual activity, Rimfire controls both ACCase resistant and susceptible wild oat biotypes and certain broadleaf weeds. It also offers good control of many grasses, such as yellow and green foxtail, downy brome, quackgrass and cheatgrass.

Rimfire features a wide application window that stretches from wheat emergence up to flag leaf with strong residual activity to reduce late flushing grasses and broadleaf weeds, including mustards and volunteer canola. Growers should apply Rimfire at 1.75 to 2.25 oz./acre with a spray adjuvant when grass weeds are in the one-leaf to two-tiller stage. Broadleaf weeds should not be larger than 2 in. in diameter at application. Rimfire may be tank mixed with most broadleaf herbicides.
