ALERT: PLEASE CALL 1-866-INVADER IF YOU SUSPECT YOU HAVE FOUND THIS SPECIES
Identification: Annual; grows 8 to 16 inches tall with few to many culms. Leaf sheaths contain white hairs when young, becoming more or less smooth once matured. The blades are rigid, sharp, pointed, and spreading. Grain 1/4 inch long, resembling a wheat kernel. Josephine county is the only known location in Oregon.
Impacts: Goatgrasses are rangeland and dryland crop invaders. This species, aside from dominating dryland pastures in California, readily crosses with wheat, producing sterile seed and unmarketable wheat. Aegilops spp. are closely related to wheat, making selective control of goatgrass difficult in cereal crop production.
Biological
Controls: Biological control agents are not used on "A" listed weeds in Oregon. This weed is being managed for eradication or containment.
