- Setaria faberi is an annual grass that can reach 2-5 ft. (0.61-1.5 m) in height.
- Leaves are up to 16 in. (41 cm) long, 0.6-1 in. (15-25 mm) wide. Sheath is round with hair on margins. Blade has short hairs cover the upper surface. Ligule has a fringe of hairs. There are no auricles.
- Flowering occurs in late summer to early fall, when a green (eventually straw colored), bristly inflorescence develops. The inflorescence resembles a foxtail, hence the common name.
- The fruit are small flattened ovoids with hard coats. They usually germinate in late spring to early summer.
- Ecological Threat
- Setaria faberi is native to Asia and was accidentally introduced in the United States in the 1920s as a contaminant of other grain. Plants invade disturbed sites such as roadsides, landfills, fence rows and right of ways.
- Herbicide Resistance
- Populations of this plant exist in the United States that are resistant to ACCase inhibitors (A/1), ALS inhibitors (B/2), and Photosystem II inhibitors (C1/5).
