Thesis Topic/Title
Reducing Spray Drift of Herbicides with Controlled Droplet Application

Description

Spray drift from aircraft applying pesticides is still a concern in many rural areas. In particular, herbicide spray drift can travel large distances downwind of the sprayed paddock. This can cause significant damage to crops, in addition to being an environmental nuisance. Several improvements in atomiser design took place in the 1990s, but a review is required to see if any further developments have taken place around the world since then. Herbicide spray drift damage continues to be the subject of regular legal action, wastes significant time and money, and is something which could be eliminated with more effective atomiser (spray nozzle) design. The most effective nozzle designs, which produce droplets mainly within the 100 to 300 micron size range, are those of the rotary atomiser type, which feature well defined fluid issuing points or teeth. Collaboration with UQ Gatton Campus is envisaged, with laser droplet sizing of nozzle prototypes at the wind tunnel laboratory based there.
