  • Glyphosate-resistant ryegrass challenge
    Glyphosate-resistant ryegrass challenge
    Issue 152, May-June 2021 - 21 May 2021

    Random weed surveys identified glyphosate resistance in ryegrass plants collected from 27 per cent of paddocks in south-eastern South Australia and 40 per cent of paddocks in south-western Victoria in the 2020 season. Herbicide resistance specialist Dr Peter Boutsalis explored the “significant increase” in glyphosate-resistant annual ryegrass at the 2021 GRDC Grains Research Update in Adelaide.
