Spot spraying put to the test with large-scale ‘artwork'

The sprayer has nozzles every 25 cm on the boom, each able to dose independently.

The technology has been developed by Agrifac since 2016, and features fast-switching nozzles that switch on and off 100 times per second.

By loading a task map into the system, spraying can be done precisely and accurately, with GPS used to spray at the exact location required.

Using environmentally friendly dye, Agrifac created a 132 m by 200 m ‘painting’ to demonstrate the technology.
