| 説明 | Introduced, warm-season, annual, tufted grass to 60 cm tall; nodes sometimes have a brown ring of glands below them. Leaves are hairless, with rigid 2-3 mm long hairs either side of the ligule. Flowerheads are contracted panicles at first, becoming open at maturity (8-24 cm long). A native of Europe, it is a weed of disturbed areas of agriculture and habitation (e.g. crops, sown pastures, gardens, roadsides and waste areas).Generally a nuisance weed, but can be competitive at times in newly sown pastures and crops. Prevention of seeding for 2-3 years eliminates the seedbank. Controls can include: heavy grazing when young, slashing at flowering, grazing and fertility management to increase the density and competitiveness of pastures, hand removal and the use of registered herbicides. |
