Abstract
Annual ryegrass (Lolium rigidum) is one of the most serious and costly weeds of annual winter cropping systems in southern Australia. It is highly competitive and can compete with a crop as early as the 2-leaf stage.
Annual ryegrass is a winter to spring growing weed that can emerge from late autumn to early spring. The number of emergence flushes and the density of plants that emerge are related to initial seedbank levels and the frequency and amount of rainfall.
