A single violation of an importing country's mrL can lead to punitive measures on all Australian grain exported to that country and undermine Australian grains' reputation internationally... All residue testing results are assessed against Australian Pesticides and Veterinary medicines Authority (APVmA) mrLs to confirm good agricultural practice and, where applicable, against the relevant overseas mrLs... traceback if a sample is found to contain a residue above the prescribed Australian mrL, a traceback investigation is undertaken to determine the cause, and the findings are reported to the nrS...

Specific management practices alter the abundance and activity of microbes capable of processing both organic and mineral-N... Once we better understand the soil biological and chemical factors governing N-transformations in our agricultural systems, we can determine how agronomic practices can be used to synchronise N supply, from both fertiliser and soil sources, with crop demand... A primary goal of this project was to develop and use molecular tools to detect these N-cycling communities in Australian agricultural systems...

"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...
