Spray operators can obtain advice on minimising the risk of spray drift by consulting the Grains Research and Development Corporation (GRDC) Fact Sheet Practical tips to reduce spray drift... The resource advises that the risk of spray drift increases substantially when spray equipment travels fast during higher speed winds... To reduce the amount of spray drift spray operators are advised to avoid travel speeds above 16 to 18 km/h during higher wind speeds unless there is excellent boom height control and equipment is set up to minimise airborne droplets by providing spray quality which is coarse or larger...

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...
