Stewart Hamilton, pictured with his workmate Wal, looks to the family's hay enterprise for weed control... Stewart Hamilton says that growing hay - field peas, ryegrass and oats - as a break crop in sequence with their grain crops has allowed them to eliminate almost all weeds from infested paddocks, lifting whole-farm productivity and profitability... Stewart says that using this approach when faced with a dry start to the season has improved germination in their hay crops, which, apart from boosting hay yields, has also helped to further smother weed competition...

Farm biosecurity wins prizes and premiums.. "Our Shepherd barley, which yielded 5.75 tonne per hectare with only two irrigations in a very tough season, was awarded second prize in the Royal Agricultural Society irrigated barley competition," Mr Grundy says... All of the paperwork is also kept up to date: "This is also an important factor, as buyers are increasingly looking for traceability of grain back to the farm," he says...

These investigated 13 herbicide alternatives for weed control in crop margin areas along fencelines, firebreaks and boundaries... Department of Agriculture and Food, WA (DAFWA) senior grains research officer Dr Sally Peltzer, who coordinates the WA adviser learning groups, says directing adviser and grower attention to the state of herbicide resistance along crop margin areas will prompt higher adoption of strategies to monitor and prevent its onset across whole properties... Surveys of growers after the trials and field days found many were prepared to use a double knock and spend more money - up to $50 per hectare - on weed control along fencelines to avoid the onset of glyphosate resistance...

Dr Hashem says a rotation of wheat/lupins or lupins/wheat followed by Roundup Ready (RR) canola and use of alternative herbicides with diverse modes of action were the keys to success... Dr Hashem says the trial compared row spacings of 22 and 44 centimetres and found that any moisture conservation benefit from using wider rows at the Cunderdin site was offset by reduced crop establishment (by 20 to 25 per cent on average for all crop types) and weed-control failure... Dr Hashem says that the use of Flexi N reduced canola establishment in both 22 and 44cm row spacing plots compared with urea, but increased canola crop vigour by 15 per cent and grain yield by 12 per cent...
