With the wide-spread adoption of glyphosate tolerant sugar beets, the demand for traditional beet herbicides has declined. There are three active ingredients, desmedipham, phenmedipham, and ethofumesate that are marketed individually as Betanex, Spin-Aid and Nortron. They also are marketed as premixes (Betamix and Progress), which are the most common forms of use in sugar beets. Because of the decline in demand and EPA requirements for changes in the formulations, Bayer CropScience has decided to discontinue manufacture and sale of Betamix, Progress, and Betanex (desmedipham). Currently, they intend to continue to produce and market Norton (ethofumesate) and Spin-Aid (phenmedipham).
This may affect vegetable growers who produce red beets, Swiss chard, and spinach, because these products also are registered for these related crops. If the current plans continue, Spin-Aid and Nortron will continue to be available and registered for vegetable use.
Bayer CropScience has a two-year supply of these products in the distribution chain, so growers who use them may want to stock up before the supply runs out.
Other herbicides labeled for beets and or spinach include Dual Magnum, Pyramin, Ro-Neet, Nortron, Stinger, Poast, and Select Max.
