Herbicide Resistance in Summer Annual Weeds of Australia’s Northern Grains Region Open
For more than two decades, glyphosate has been relied on to control summer annual weeds in fallow systems in Australia’s northern grains region. With numerous cases of glyphosate resistance reported in weed species collected from this regi…
