paraquat and spray.seed (paraquat/ diquat) are not registered for pre-harvest application in cereal or oilseed crops and should not be used under any circumstances including in-crop spray topping, pre-harvest canola dessication or under-the-cutter-bar spraying during swathing or windrowing canola... DO NOT use on crops intended for seed DO NOT harvest for 5 days after application to standing crops DO NOT overspray windrows DO NOT apply to standing crops and again at the time of windrowing.. Keeping an accurate spray diary and adhering to recommended application timing and spray intervals as per the label is crucial...

The responsibility to avoid herbicide residues in delivered cereal, pulse and oilseed grains sits squarely with grain growers and their advisers... residues: Late herbicide applications to crops increase the risk of detectable herbicide residues in harvested grain, potentially leading to breaches of maximum residue limits (MrLs)... Paraquat is not registered for: - in-crop spray topping; - pre-harvest crop desiccation; - under-the-cutter-bar spraying during swathing or windrowing activities; - pre-harvest weed control; - spraying over the top of swaths or windrows..

Herbicide hangover troubles crop selection.. Farming in Victoria's Mallee region, Rohan Mott was more than happy with his first crop of Compass barley, which yielded four tonnes per hectare in November from only 125 millimetres of growing-season rainfall... At Turriff East, in north-western Victoria, the Motts are making good use of the family's on-farm storage complex to provide their own segregation while working to direct-market the crop with a malting company and other contacts...

Residual herbicides have become an important tool in the war against weeds for many northern region growers in recent years... Growers are urged to carefully consider their plant-back options for the 2014 winter season in country previously treated with in-crop or fallow residual herbicides as label recommendations for replant intervals usually require a minimum amount of rainfall to kick-start breakdown of the residual herbicide... To determine what crop can be safely sown following a residual herbicide application growers need to calculate the herbicide rate, quantify the amount of rainfall from the date of application up until sowing the plant back crop (excluding isolated storm events during summer) and carefully consult product label recommendations...

Australian grain growers have progressively adopted a number of best management practices in order to minimise soil tillage, which is one of the main causes of soil erosion, soil compaction and soil organic matter loss... Little is known about how the increased application of herbicides affects soil biota and soil functions that sustain crop growth and ecosystem services such as crop residue turnover, water holding capacity, soil carbon storage and nutrient cycling... The project will address current knowledge gaps regarding the impact of herbicides on soil biota in all three growing regions of the Australian grains industry. The project objectives include determining the effects of different herbicides on not only soil biological communities and biodiversity, but also quantifying their effects on soil functions critical to ecosystem health...

"Due to the dry spring and autumn, herbicide residues were likely to show up in the 2013 growing season, providing us with a great opportunity to investigate the effects of tolerant versus intolerant varieties of wheat, barley, canola and lentils," Mr Wallis said... Mr Wallis says the research was of particular interest as more growers incorporated imi-tolerant varieties into their cropping systems to combat hard to kill weeds... "It is strongly recommended that growers using imidazolinone herbicides go back in with a tolerant variety in the subsequent year, unless rainfall has exceeded the plant-back requirement listed on the herbicide label," he said...

Other reasons for late season herbicide use include management of other late season weeds just prior to harvest, and pre-harvest crop desiccation to accelerate or even-up crop ripening... Information about stewardship for late season application of herbicides in winter crops is available in the new Grains Research and Development Corporation (GRDC) Late Season Herbicide Use Fact Sheet ...
