Black-grass is an annual grass-weed propagated by seeds, predominately (80%) germinating in the autumn. It is a competitive weed 12 plants/m2 resulting in a 5% yield loss in a wheat crop. Crop profit can be severely impacted by yield loss, herbicide spend and cultural control measures e.g. delayed sowing.
Black-grass has an increasing distribution throughout the UK, Europe, Asia and North America. Herbicide resistant populations are now found widespread across the UK.
