Practical Weed Science for the Field Scout: Corn and Soybean
Barley, foxtail, or Squirreltail (Hordeum jubatum)
Winter annual grass
An erect short-lived perennial grass that grows throughout the winter months and therefore is mistaken to be a winter annual. This weed is found most commonly as a weed of agronomic crops, pastures and roadsides. Foxtail barley ranges from 10 to 24 inches in height and has a conspicuous "foxtail" seedhead. Mature plants have leaves that are 2 to 6 inches long, are without hairs or auricles and have a membranous ligule. Leaf sheaths may be without hairs or may have a few sporadic short hairs. The seedhead is a nodding, bristly 2- to 4-inch-long spike that initially has a greenish to purplish tint and becomes pale with age.
