Drought '99 Ohio State University Extension Using soybeans for silage and hay - Herbicide considerations Dry weather has led to interest in areas of Ohio in using soybeans for silage or hay. Unfortunately, most soybean herbicide labels specify that treated soybeans should not be fed to animals as silage or hay. For soil-applied herbicides, only some of the older products, including Sencor, Lasso, Prowl, and Dual, permit these uses of treated soybeans. Among postemergence herbicides, only Basagran and FirstRate labels specify that soybean silage or hay can be fed. The Roundup Ultra label for Roundup Ready soybeans allows soybean silage or hay to be harvested, but is not clearly stated. Soybeans can not be harvested for silage or hay if Roundup Ultra is applied as a harvest aid. Poast and Poast Plus labels allow feeding of soybeans as hay, but not as silage.
