The initial adoption of Flexi-N was driven by the convenience of storage and handling, improved speed and uniformity of application, and reduced labour requirements when applied with pesticides... Crop Updates is a partnership between the Department of Agriculture, Western Australia and the Grains Research & Development Corporation 37.. The trials suggest that applying fungicides in large droplets at water rates between 60-80 L/ha will be beneficial in a range of seasons in the Mingenew area...

New research has shown that trifluralin sprayed with higher water rates of about 100L/ha improves the herbicide's effectiveness on paddocks with heavy stubble loads, regardless of the spraying speed... Dr Borger said that in trials conducted at Cunderdin and Wongan Hills in 2011, the amount of annual ryegrass which survived 2.5L/ha of trifluralin decreased from 19 to 14 per cent when the water rate was increased from 50 to 100L/ha... " the results show that trifluralin should still work well in most areas of WA, as long as it is applied correctly, and that cases of reduced effectiveness will usually be due to lower water rates on heavy stubble loads, not resistance," Dr Borger said...

" Agribusiness Crop Updates 2010 Herbicide control of slender iceplant Lorinda Hunt, Department of Agriculture and Food, Western Australia, Three Springs, Andrew Blake, Department of Agriculture and Food, Western Australia, Geraldton Research conducted by L Hunt... In the short stubble-no chaff plots (where stubble biomass was lowest), water rate did not have a large impact on annual ryegrass control, although Sakura was more effective at the high water rate... In the short stubble-chaff plots, all herbicides were more effective at the high water rate...

Controlling winter weeds a top priority for growers.. With warmer than average winter temperatures accelerating the growth of northern wheat crops, it is imperative that growers give top priority to weed control this season to maximise crop productivity and avoid the costly issue of herbicide resistance... GRDC manager regional grower services - north, Sharon O'Keeffe said cereal growers needed to employ a variety of tactics to effectively combat weeds including an early spray program, robust spray rates and correct spray application with consideration given to timing, wind speed, water rate, applicable droplet size, boom height and travel speed...

"In high grass weed densities, growers need to be particularly careful that tank mixes aren't going to antagonise or reduce the efficacy of any group A herbicides which already exhibit issues with weed resistance."..
