Reducing spray drift - Keeping it in the paddock.. Biosecurity SA has been working with stakeholders on actions to reduce the risk of economic damage to commercial vineyards and other sensitive crops from off-target drift of herbicides and has held preliminary consultations on possible further actions, including regulation... Biosecurity SA is seeking comment from stakeholders on proposed amendments to the Agricultural and Veterinary Products (Control of Use) Regulations 2004 to reduce the risk of economic damage to commercial vineyards and other sensitive crops from off-target drift of Group I herbicides...

It has also been proven that reduction in ascospore release as a result of chemical treatment leads to a reduction in disease incidence in an adjacent crop... , the project team investigated chemicals that were effective in manipulating pseudothecial development and ascospore release and what effect a reduction in inoculum had on canola plants immediately adjacent to the treated residue... Although the application of chemicals to canola residues will not provide total control of the disease, it has the potential to provide growers in high disease pressure areas with a window of opportunity in which to minimise seedling infection...

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...

Darren Aisthorpe, Queensland Department of Agriculture, Fisheries and Forestry (DAFF) extension agronomist for the CQ Grower Solutions project, Biloela says the double knock technique is a key strategy for management of difficult-to-control weeds such as flaxleaf fleabane and feathertop Rhodes grass... "To date there have been some very mixed results with double knocking at a commercial level, despite excellent results at trial and demonstration levels, and this is not helping with the uptake of the practice," Mr Aisthorpe said... The Grains Research and Development Corporation (GRDC) has invested in weed management research across the northern region, including extensive work by the DAFF weeds team, CQ Grower solutions project and Northern Grower Alliance (NGA) into maximising effectiveness of the double knock technique...
