How do you minimise spray drift while ensuring reliable efficacy when spraying herbicides in summer?
Achieving this balance will be discussed during a short Spray application in summer fallows webinar, supported by the Grains Research and Development Corporation (GRDC).
Targeted at advisers, it is one of a series of national weed management webinars, hosted by ICAN Rural, which will feature presentations from industry experts.
ICAN Rural senior consultant Mark Congreve said the spray application webinar was particularly relevant to Western Australia.
“Changing weed species, changing climate patterns and the requirement for double knock applications using contact herbicides to control difficult weeds has seen a significant increase in summer fallow herbicide applications in most broadacre no-tillage farming systems in WA,” he said.
“The webinar, presented by leading spray application adviser Bill Gordon, will discuss how to effectively manage water rates, nozzle selection, boom height and ground speed under the rapidly changing daily environmental conditions that typically occur during summer.”
The free webinar will be held at 7am (WA time) on December 6 and run for about 30 minutes, followed by time for questions.
Other webinars to be held as part of the ‘Advances in Weed Management’ series are:
- Managing fleabane in zero-till farming systems, November 29: This webinar will highlight the ecology of fleabane and why this is driving the spread of fleabane across the nation. It will also discuss the glyphosate resistance status of the weed and weed control tactics that have been successfully employed in Australia’s northern cropping region.
- Understanding stubble and soil binding of pre-emergent herbicides used for ryegrass control in winter crops, December 13: This webinar will investigate the properties of key pre-emergent herbicides pyroxasulfone (Sakura®), prosulfocarb/s-metolachlor (Boxer® Gold), dimethenamid-P (Outlook®) and trifluralin (Treflan®) and how the herbicide properties affect stubble binding and soil mobility.
Pre-registration is required so that participants receive a link to the simple-to-use webinar software.
