    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.

    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

    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.
