WebDec 29, 2024 · Herbicide resistance is an important weed management issue. Glyphosate is the most dominant herbicide, which controls a broad spectrum of weeds, including grasses such as Lolium rigidum. Lolium rigidum is a major weed of winter crops in Australia that is developing glyphosate resistance in increasing numbers of populations and has … WebThe evolution of glyphosate-resistant (GR) weed variants has been significantly slower than the evolution of resistance to most other commonly used herbicides, 1 but their …
