Take home message Take the time to look hard at your cropping rotation and how chemicals fit to ensure longer term success... In 2007 samples of wild oats were tested with the following herbicide resistance results :- 20% to Wildcat , 10% to Topik , 30% to Atlantis and 15% to Mataven ... To avoid or reduce herbicide resistance to Groups A, B & Z we need to consciously rotate to other chemical groups such as Group C, D & J. If the opportunity arises in the rotation where proper incorporation can be achieved, the use of Trifluralin (D) and Avadex (J) should be considered...

Farming systems which minimise the movement of soil and water will also minimise the loss of nutrients and pesticides... Overall, the only large difference was the lower Zn when superphosphate was applied... In summary, Mike has found a strategy to help him interpret his yield maps - and is now taking the same approach to other paddocks to maximise fertiliser savings...

In the short term (at least the next 8 years), these crops will in essence provide new uses for old herbicides and old herbicide groups... In summary, the research also indicates that the public is least likely to approve of GMOs that: Benefit a company over the public; Involve gene transfer from species that are not closely related; Are not undertaken for a societal benefit; Are perceived as being possibly harmful to people or the environment; or Is a food over a non-food application... At the outset of the project, a draft strategy was proposed, and it was this strategy that the project team and participant growers/consultants worked towards implementing and evaluating...

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...

While a cereal crop can shade broadleaf weeds, the weeds will still move their leaves to get the maximum benefit from any sunlight reaching them through the crop canopy... Crops sown in an east-west orientation are less successful in suppressing the growth of broadleaf weeds compared with grass weeds... Crop orientation will have a greater impact on farms in southern Australia, compared to northern Australia...

Feathertop Rhodes grass has a short seed life, so focused control measures over two years could bring the weed in check... Pre-emergent herbicides have a role to play as part of an integrated weed management (IWM) strategy to control feathertop Rhodes grass (FTR), but they are not a standalone solution... While residual herbicides are far from the solution, Mr Daniel says, they are one of the critical tools in controlling a range of weed species, including FTR...

We operate a mixed farming enterprise, 'Millring Pastoral', running sheep, cattle and cropping across 2400ha... The sheep enterprise includes merino ewes, producing fine wool averaging 19 micron, and 1st cross ewes and prime lambs... My study topic was 'The integration of livestock and cropping in the high rainfall zone.' I travelled for a total of 16 weeks to a number of different countries including the United Kingdom, the United States, Canada, Mexico, Brazil, Uruguay, and New Zealand...

Leave no survivors in fleabane fight.. Driving down the seedbanks of difficult-to-control weeds such as flaxleaf fleabane requires diligent monitoring and control of herbicide survivors... " the approach will drive the seed bank down to very low numbers within several years, with few problems in following years," Dr Walker said...
