    Wet years a potential challenge for global market requirements

    Wetter-than-normal conditions in recent years highlight a potential certification challenge with aerial spraying. Sustainable Grain Australia (SGA) is working to clarify that. SGA, in conjunction with CBH in Western Australia, acts on behalf of Australian growers and traders to help manage certification requirements and expectations. It was discussed at a GRDC webinar, which came about after the topic of aerial applications was raised at several recent National Grower Network meetings.

    Getting the most from aerial spraying

    Achieving the best crop management outcomes possible with aerial applications was discussed at a GRDC webinar, which came about after the topic of aerial applications was raised at several recent National Grower Network meetings. Advantages of aerial applications, include quicker application and access during wet years. Communication with the operator is key to obtaining the best possible results. This centres on defining the spray parameters, which includes ensuring a product is registered for aerial application and the operating environment on-farm for the aircraft.

    New strategies for tackling problem weeds

    Through its National Grower Network, GRDC is supporting trials investigating up-to-date control measures for marshmallow in crop and pasture systems and the control of grass weeds in oat crops for Western Australian growers.

  • Australia’s number one weed creeps northwards

    Australia’s number one weed creeps northwards

    Growers moving fodder and harvest machinery are encouraged to take extra care to avoid spreading invasive weeds such as annual ryegrass and parthenium. University of Queensland Professor Bhagirath Chauhan says the movement of annual ryegrass-infested fodder and machinery has caused the weed to spread north. The greatest weed threat to New South Wales is considered to be parthenium. Since April 2020, 49 parthenium infestations have been detected and are being eradicated following movements of contaminated hay, grain, vehicles and machinery from Queensland.

    Added diversity reduces wild radish control evasion

    Wild radish has developed resistance to multiple herbicide modes of action, prompting the need for more non-herbicidal, integrated weed management solutions. Studies by Dr Michael Ashworth’s Australian Herbicide Resistance Initiative team reveal wild radish is now adapting to evade harvest weed seed control by shedding seeds early. To counter this, incorporating various weed control methods and leveraging modern machinery and weed mapping technologies are essential.

  • Is human ingenuity winning the war on weeds?

    Is human ingenuity winning the war on weeds?

    Ray Harrington has spent more than six decades innovating and adapting sustainable farming practices. This has included minimum tillage and developing tools such as the harvest weed destructor to combat herbicide-resistant weeds and improve cropping efficiencies. His collaborative efforts with researchers and continuous adaptation to evolving agricultural challenges reflect his commitment to advancing farming techniques and supporting the farming community.

  • Proactive approach to weeds takes time

    Proactive approach to weeds takes time

    Having the time to be proactive is one of the challenges when managing weeds for Peter Bach, who farms 1000 hectares near Pittsworth in south-eastern Queensland, with his wife, Kylie. Peter employs multiple tactics to keep on top of ryegrass, barnyard grass, feathertop Rhodes grass and Johnson grass but says other on-farm jobs often pull him away from weeds and the need to be on top of them constantly.

    Unearthing insights – how amelioration affects weed management

    Insights into the diverse effects of tillage on weed ecology, seed burial patterns and herbicide performance after strategic deep tillage are better informing weed management. GRDC supported research with DPIRD is pointing to more informed weed management practices to help ensure the longevity of strategic deep tillage amelioration.
