Grain growers in the southern cropping region are being advised that they can take action to improve weed control in wheel tracks during summer fallow spraying... A Weed Control in Wheel Tracks Fact Sheet , produced by the Grains Research and Development Corporation (GRDC), details measures that can reduce poor control of weeds in the sprayer's wheel tracks and adjacent areas during summer fallow applications... Lack of weed control in these areas can be the result of poor spray deposition, excessive dust or a combination of the two...

Sprayer setup and using good quality water are critical to ensure full rates of glyphosate are getting to the weeds... Dr Boutsalis says a common reason for poor weed control when using glyphosate is herbicide resistance, ranging from weak resistance to strong resistance... Plants with weak resistance are often controlled with maximum label rates of glyphosate, Dr Boutsalis says, but relying on a herbicide-only option will develop resistance to very high rates...

"The research is investigating a range of spray application issues, including the best combination of nozzles, spray pressures and pesticide formulations to minimise drift and optimise efficacy," Dr Young said... "The GRDC is funding research on spray drift reduction technology because we want to ensure any new buffer zone requirements are based on the latest technology and, importantly, Australian conditions," Dr Young said... Dr Young said the focus of the new training project would be to continue to raise awareness of spraying best practice and to increase the number of skilled people who can provide quality information and training to growers...

" GRDC Grains Research Updates 5-6 March 2013, Northern Region, Goondiwindi QLD. Bill Gordon 24 September 2013 Bill Gordon, Bill Gordon Consulting, talks about the ramifications of using a larger sprayer and whether this means better results or bigger problems... Increased capacity can improve results, if the sprayer is operated within its limits, but higher travel speeds and larger droplet sizes can create new problems for deposition... Technology to reduce spray drift GCTV: Drift Reducing Technology..

- By Bill Gordon and Graham Betts We probably have more options for modifying sprayer set-up than many growers actually know what to do with... Growers can spend a lot of time deciding what options they may want on the sprayer, which often adds to the cost... The often-neglected issue when buying a sprayer is how much time and money are invested in one of the most important parts of the sprayer - the operator...

In order to maximise the benefits of fallow sprays, Dow AgroSciences' Rob Buttimor says they need to be managed to the same degree as in-crop sprays so growers do not end up with a mess in the spray tank... "Growers using 2 percent AMS in soft water are effectively wasting their money," Mr Buttimor says... By adding lots of other ions to the spray tank in the form of hard water or soluble liquid herbicides, it neutralizes these charges and the oil droplets can come together to form large oil droplets, oily gels or general glug that will float to the top or sink to the bottom of the spray tank...
