Turfgrass Weed Control Database
The Turfgrass Weed Control Database contains the same information and pictures included in the Miscellaneous Publication MP-521. The weeds are arranged alphabetically by scientific name because common names vary and thus be inaccurate.
Purple Cudweed, Gamochaeta falcatum
Cudweed species are biennial plants but are relatively easy to control. Two, three, and four way broadleaf herbicides control postemergence as do and repeat applications of metsulfuron (Manor, Mansion, Blade, etc.). Apply in the spring while in rosette stage and before seed stalk formation.
