I recently was asked how to control nutsedge that was coming through beds that will be planted with peanuts soon. A high rate of glyphosate is a good start. After several days or just before planting, apply a burndown rate of paraquat to control what remains. The options in the peanut crop depend on the nutsedge species (e.g., yellow versus purple) and your rotation options the following year. There are more flexible options with yellow nutsedge compared with purple nutsedge. Regardless, it is important to control nutsedge as well as possible prior to emergence of peanuts. The one-two punch of glyphosate followed by paraquat can be an effective approach.
