Weed Family: Poaceae
Description
Barnyardgrass is a summer annual which has tillers that lie flat and form secondary roots resulting in a mat formation. The leaves of barnyardgrass are rolled in the bud and contain neither a ligule nor auricles; the sheath is open but compressed. The mid-vein is thick and keeled; roots are fibrous. Barnyardgrass spreads by seeds which germinate in late spring and early summer. The seedhead is a coarsely branched green to purplish panicle with spiked awns. Barnyardgrass is found throughout North America and Mexico.
Herbicide Use
Make a pre-emergence herbicide application prior to the seed germination. For post-emergent control use a product containing MSMA.
