3) It is widely accepted that fungicide applications are generally most effective when applied with small-droplet technology, but such applications are also associated with the highest risk of spray drift... The project is about optimizing pesticide spray applications by: identifying spray technologies and spray settings with low risk of spray drift, applying pesticides in accordance with latest knowledge about pest behaviour in response to pesticides and minimizes the risk of target pests developing resistance, and by using pesticides with documented efficacy against target pests... A key nozzle technology on which we will focus is air-inducted nozzles and we will screen several popular ones first in the wind tunnel to select those that produce good control of droplet size with at least 20% air inclusions by volume...

Ashley Ramm uses a self-propelled boomspray fitted with low-drift nozzles to improve efficiency and herbicide efficacy... The machine is fitted with triplex nozzle bodies that allow Mr Ramm to block off every second outlet and spray at lower water rates (less than 50 litres/ha) were applicable (500mm nozzle spacing) while maintaining a line pressure suitable for his nozzles... Mr Ramm says the sale of all sheep almost two years ago gave him the opportunity to be away from the farm for up to two weeks, which allows him to send his children - aged 13 and 11 - to high-quality schools located five minutes from their Mandurah home.

Using a 50cm nozzle chart, we find that we could use an 015 orifice at 7 bar, an 02 orifice at 4 bar or an 025 orifice at 2.5 bar... STEP 3: Identify the types of nozzles based on their operating pressure at the average speed, and identify the most appropriate minimum operating pressure for each nozzle type (the SPRAYWISE charts are useful for evaluating suitable minimum operating pressures for each of the nozzles).. For example you may choose a nozzle that is coarse at your lower volume range and medium at higher volume to go from fallow to in-crop in winter (such as a pre-orifice nozzle or low pressure air induction), and have another set that stays coarse through your volume range to do summer fallow and pre-emergent spraying (such as a coarser low pressure air induction)...
