Growers that have the weed seed bank under control will save herbicide costs; be able to use diverse tactics that would otherwise be cost prohibitive; and, by reducing the frequency of herbicide applications, will delay the onset of herbicide resistance... With any discussion on managing resistance we need to start with the basics and understand why we have the problem in the first place... Registration of high application rates by this technique may allow the control of resistant weeds that have survived a preceding application of a different mode of action...

The new Gunnedah population on the left looks healthy, showing it has a much higher level of resistance compared to the sample in the centre which is known to be susceptible, and the original resistant Moree population on the right... The world's third case of glyphosate resistant liverseed grass has been confirmed in northern New South Wales, seven years after the first two cases were confirmed from east of Moree... "While this is only the third confirmed case of glyphosate resistant liverseed grass in seven years, it comes from a new area and has a much higher level of resistance than previous populations," stated Tony Cook, Technical Specialist (Weeds) with NSW Department of Primary Industries...

Research by the Western Australian No-Tillage Farmers Association (WANTFA) shows effective use of pre-emergent herbicides when sowing wheat early in dry conditions can help the crop out-compete weeds and lift yields... Dr Minkey says the research indicated that Sakura and Boxer Gold helped control weeds when wheat was dry-seeded early, but the effectiveness of trifluralin was limited on heavy soils. ".. Overall, Sakura was the most effective in controlling germination of annual ryegrass in both early and late-sown wheat," Dr Minkey says...

The aim of the study was to investigate weed management with pre-emergent herbicides and weed seed harvest management under a dry seeded wheat system... In a UWA trial located nearby results did show a small reduction in emergence from windrow burning and the HSD (Mike Walsh, personal communication)... WANTFA would like to acknowledge the Rural Industries Development Corporation (RIRDC), the National Adaptation and Mitigation Initiative (NAMI) funded by the Department of Agriculture and Food Western Australia, the Grains Research and Development Corporation and the Australian Government's Climate Change Research Program for funding the work...

The results of the experiments have given Jeff the confidence to realise that he does have a viable, cost-effective alternative knockdown herbicide to glyphosate... Double knockdown (T 2.2b, page 128) Weather permitting, a double knockdown is implemented on resistant ryegrass paddocks prior to sowing using two non-selective herbicides (glyphosate followed by paraquat + diquat or paraquat, the choice being dependent upon the range of weeds present)... Helpful advice The Grays still enjoy the challenges and can see that they have made enough progress to feel they are being successful in managing a serious annual ryegrass problem...

Strategy: Avoid using Picloram in sorghum crops if double cropping back into chickpeas... In the short term, the decision on row spacing and planter configuration will in most cases be largely determined by the: planting equipment and machinery available at the time current paddock and farm layout tillage practices... Growers must seriously consider planting time, and weigh up the potential yield benefits of early planting against the risk of frost and cold temperatures at flowering...
