Yellow Foxtail
Scientific Name: Setaria glauca
Weed Family: Poaceae


Yellow foxtail is a summer annual which germinates when soil temperatures reach 65 degrees F. The leaves are rolled in the bud. The ligule is a fringe of hairs, and the auricles are absent. The collar is narrow and continuous. The blades of yellow foxtail contain hairs near the ligule. The growth habit of yellow foxtail is erect. The seedhead is a bushy, erect spike which resembles the tail of a fox. Foxtail is found throughout the United States, but is heaviest in the Midwest and East. 

Herbicide Use
