Effectiveness of UAVs for Spot Spraying Large Urban Trees During Incursion Responses

Biosecurity outcome

Improved methods to achieve effective UAV spot spraying of pesticides into a large tree canopy such as might be required for an incursion response in an urban environment.

Science outcome

Providing unique data set to quantify:
o The attenuation of wake-driven turbulence within a 8-15 m tree crown and to qualitatively assess the associated risk of causing insect or pathogen spore dispersal.
o Within-canopy spray distribution and overall application efficiency
o Spray drift – assessing environmental risks.
