WEST LAFAYETTE, Ind. – Yellow nutsedge (Cyperus esculentus) is a troublesome, difficult-to-control weed that is often found in turf areas. It is also called chufa, nutgrass, or watergrass.

It is important to remember that yellow nutsedge is not a grass or broadleaf weed, but a sedge. There are many sedge species, but yellow nutsedge is the most problematic. Sedge control requires different herbicides and application timings than grasses and broadleaves,so understanding the biology of sedges is important.
