Far-Go Receives Label for Use in Sugarbeet

The U.S. Environmental Protection Agency recently granted a label for use of Far-Go herbicide for wild oat control in sugarbeet.

According to Alan Dexter, extension sugarbeet weed control specialist for North Dakota State University and the University of Minnesota, Far-Go is a preplant incorporated herbicide that provides a mode of action different from Select, Prism, Poast and Aussure II, which are postemergence herbicides widely used in sugarbeet.

"All the postemergence herbicides for grass control have the same mode of action, so use of Far-Go with a different mode of action will reduce the risk of developing a wild oat population with resistance to the postemergents and will control wild oat that have already become resistant," Dexter says.

Far-Go can be applied in the fall or in the spring before planting. It is available in a 4-pound-per-gallon active ingredient formulation or a 10 percent active ingredient granular formulation. Liquid Far-Go also can be impregnated on dry fertilizer and applied with the fertilizer, he says, but a minimum of 150 pounds per acre of fertilizer product is required and many sugarbeet fields do not need this much fertilizer.

Far-Go should be incorporated immediately after application with a field cultivator plus a harrow or rolling crumblers set to operate 3 to 4 inches deep. Two incorporations are recommended in the spring. A single incorporation in the fall followed by a spring tillage is adequate for fall-applied Far-Go.

In the fall, Far-Go should be applied within three weeks of normal freezeup or until snow cover or the ground becomes too frozen for incorporation. Generally, says Dexter, starting Far-Go application after Oct. 15 is a good guideline.
