The Yellow Nutgrass is a whole nother thing. I Added about 3 acres of old pasture to my bean/corn field last year and had an explosion of it after I planted this year.Unfortunately its in an area I have planted in a 5 way summer mix and I will have to address it next year.In my area Nutgrass brings hogs and I do not want them around if possible.Will give the Imox a try on the Sedge in the Clover plot.
