Suppression of the grass weed annual ryegrass, Lolium rigidum by wheat, triticale and rye was compared in field trials at Wagga Wagga in 1993. Cereal rye and triticale appeared to be more competitive than wheat, with a biomass of annual ryegrass at maturity of 70g/m2 with triticale compared to 170g/m2 with wheat. Early seedling vigour, superior height and broad leaves appeared to influence the greater competitive ability of the triticale and cereal rye.
