    Why GRDC invested in the Herbicide Innovation Partnership in 2015

    Australian grain growers face a significant challenge, with weeds causing an estimated annual loss of $3.3 billion, approximately $146 per hectare. This issue, the most costly for global crop production, is exacerbated by a dramatic decline in new herbicide development and increasing herbicide resistance.

    Lessons for navigating resistance storms

    The annual Crop Protection Forum, convened by the Australian Herbicide Research Initiative, is a key event where scientists, agronomists and growers come together to share the latest in advances for weed, insect and disease management. Titled the ‘Storm of resistance’, the 2023 event brought urgency to addressing the matter with integrated management systems and novel approaches.

  • Researcher encourages pre-sowing fenceline sprays

    Researcher encourages pre-sowing fenceline sprays

    Spraying fencelines in early autumn enables weeds to be targeted when they are small

  • Annual ryegrass targeted for termination in every crop

    Annual ryegrass targeted for termination in every crop

    Tim Williams says the decision to buy a Seed Terminator is paying off with less reliance on pre-emergence herbicides in some crops.

  • Collaborative weed control a winner against Feathertop Rhodes grass

    Collaborative weed control a winner against Feathertop Rhodes grass

    New research has found that collaborative and agronomic weed management strategies can reduce the spread of Feathertop Rhodes grass (FTR) in Queensland and New South Wales.

  • Harvest weed seed control embraced to target escapes
    Weeds, 31 Oct 2023
    Harvest weed seed control embraced to target escapes

    For the past six years, harvest weed seed control with chaff carts and now a mill have been used as a tactic to manage weeds.

  • Grower networks raise awareness of ‘under-the-radar’ challenges
    Weeds, 26 Sep 2023
    Grower networks raise awareness of ‘under-the-radar’ challenges

    Investment through GRDC’s National Grower Network allows weeds that pose localised challenges to cropping systems to come under examination as part of efforts to optimise control strategies

  • Roadside slashing a good option in addressing weeds
    Weeds, 18 Sep 2023
    Roadside slashing a good option in addressing weeds

    Managing roadside feathertop Rhodes grass with frequent slashing, while addressing weed spread at paddock boundaries, shows promise.

  • Weed movement tracked to help inform management plans
    Weeds, 13 Sep 2023
    Weed movement tracked to help inform management plans

    Using genetics, research is helping to uncover weed mobility, which is important data for area-wide management approaches.

  • Nucleic acids – a next-gen weed management tool
    Weeds, 14 Aug 2023
    Nucleic acids – a next-gen weed management tool

    Herbicide resistant weeds are continually evolving in farming systems and new management solutions are being sought. Associate Professor Todd Gaines from Colorado State University in the USA is investigating molecular based strategies that could precisely target problem weeds. He is sharing his learnings with the Australian industry whilst on sabbatical at the Australian Herbicide Resistance Initiative.
