Pest Details



Native to Eurasia where it can be a severe weed problem. Now widespread throughout the United States, but less of a problem here.


An annual grass forming dense clusters of stems. Reproduction is from seed.


Mature plants form dense clusters of stems and may be up to 2 feet tall. Stems are slightly rough to the touch. Leaf blades are only 1/8 inch wide and 3 to 4 inches long. They are smooth, and at their base there is a long, papery ligule forming along the stem. The flower head is a dense but slender seedhead that tends to taper to a more narrow point at both the top and bottom ends. It may be up to 4 inches long and is densely packed with the flowers and seeds. An awn is present and is distinctly bent or curved.
