Rigid Ryegrass
Reduced Sensitivity to paraquat evolves under selection with low glyphosate doses in lolium rigidum
This is the first report of low-dose glyphosate selection causing a shift towards paraquat resistance. Herbicide resistance in weed species is a serious threat to world agriculture. We report rapid resistance evolution in the genetically variable cross-pollinated grass weed Lolium rigidum when recurrently selected with low doses.
