has been proven to reduce Lolium infestations dramatically, clear evidence of the value of new weed-control tools in prolonging the life of herbicides.

KEY POINTS

images   When ryegrass pastures were converted to wheat production in Australia, ryegrass (Lolium) became the main weed.

images   Australian farmers have developed and adopted several “harvest weed seed control” (HWSC) systems that effectively target annual ryegrass and other weed seeds during the harvest operation. The use of HWSC in addition to herbicidal weed control now has been proven to reduce Lolium infestations dramatically.
