IPM1007, Revised November 2009
Winter annual broadleaf
A low-growing winter annual weed primarily of fallow and no-tillage agronomic crops. Seedling leaves are small and linear in outline, leading most to believe this plant is a grass rather than a broadleaf weed. Mature plants also have leaves that are linear in outline, no more than 3 mm in width, shiny, and without hairs. Flowers are small and consist of five very small white to yellowish white petals. The plant derives its name from the cylindrical, compressed spike that contains more than 100 carpels and resembles a mouse’s tail.
