Stinkgrass
Stinkgrass

A summer annual grass that emits a distinctive odor. Stinkgrass is a common grass weed of many agronomic crops, pastures, hayfields and noncrop areas. Seedlings develop into tufted plants relatively quickly. Leaves are rolled in the bud and are approximately 5 to 10 mm wide. Leaves are smooth and glossy below while upper leaf surfaces are rough and may have hairs along the margins. Auricles are absent and the ligule is a fringe of hairs that are usually less than 1 mm long. Sheaths are round to slightly flattened, without hairs except occasionally where the leaf joins to the sheath. Seedheads are triangular panicles that have a grayish green cast.
