(Setaria glauca)
Drawing by Andrew Schaible 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 most heavy
in the Midwest and East.

Cultural Practices:
Do not seed, core aerate or verticut when soil and weather conditions are appropriate for germination. When foxtail
begins producing seedheads, lower your mowing height. Foxtail is generally not a problem in well established vigorous
turf sites
Herbicide Use:
Use a preemergent herbicide containing siduron when establishing turfgrass from seed. Postemergent herbicide app-
lications may damage desirable seedling grasses. Follow university extension center recommendations for your area.
