Data on spray quality is usually obtained by using water when spray liquids contain agrochemicals with inert surfactant systems, and frequently, added adjuvants... The impact of adjuvants is not constant and may vary with concentration, nozzle type and pressure (Figure 1)... (Figures 1 & 3) adjuvants containing lecithin or other type of oils will usually decrease the amount of driftable fines (Figures 1, 2 & 3)...

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...
