Some species, particularly L. temulentum, are which can have a severe impact on the production of wheat and other crops. Annual ryegrass ( L. rigidum) is one of the most serious and costly weeds of cropping systems in southern Australia, and herbicide resistance is a frequent problem. When Does Annual Ryegrass Die Ryegrass pollen is also one of the major causes of hay fever. , including those at the All England Lawn Tennis and Croquet Club, the venue for Wimbledon, are planted with ryegrass..
