University of Adelaide's Dr Gurjeet Gill says growers in the Pinery fire zone will need to seed quickly following the sprayer to avoid problems with drifting... Growers with bare soils affected by fire are being asked to be mindful of pre-emergent herbicide rates ahead of seeding in 2016, with a lack of organic matter on the surface meaning chemicals will penetrate the soil more readily than normal... Dr Gill says growers will need to seed quickly following the sprayer to avoid problems with drifting...

No pre-emergent herbicide in Australia has on-label recommendations for disc seeders.. The study, conducted by the University of Adelaide and University of South Australia with support from the Grains Research and Development Corporation (GRDC), aims to refine the industry's understanding of the use of disc seeders in conjunction with pre-emergent herbicides and inform future on-label advice... University of Adelaide researcher Sam Kleemann said although growers increasingly recognised the advantages of disc seeders, many pre-emergent herbicides' on-label advice forbids use alongside disc seeders, and chemical companies often won't support the use of disc seeders because of a lack of information around the machinery's impact on crop safety...

The trial plot is showing crop damage with pre-emergent herbicides due to poor separation of herbicide and crop seed... "Our rule of thumb is that five to 10 millimetres of rainfall in the 10 days after sowing is fine for Boxer Gold but 10 to 15mm is required for Sakura .".. " Sakura and S-metolachlor in Dual Gold and Boxer Gold are not bound tightly and are prone to movement in soils with low organic matter...

Achieving good pre-emergent spray results.. Getting a good result from pre-emergent herbicides is about getting every part of the application process right, starting with your product selection to match the weed spectrum present, through to monitoring the spray results carefully... When using air induction nozzles in heavy stubbles, consider using larger than a very coarse spray quality (e.g. extremely coarse) to maximize the penetration and minimize retention of the product on the stubble...
