If farmers are still unconvinced about the effectiveness of spot spraying, Agrifac’s latest creative exercise might just change their minds.
To prove a point, the Dutch agriculture machinery specialist took one of its tried and tested Condor self-propelled sprayers that is equipped with spot spraying technology out to a snow-covered paddock in the Netherlands, filled the product tank with environmentally friendly dye, and proceeded to “spray paint” a super-sized portrait of the Mona Lisa, along with Agrifac’s logo and the line: “We are ready! Are you?”

To do that, the company simply made use of technology already available to farmers since 2016. By loading a taskmap into the sprayer and switching on GPS, the operator was able to program the sprayer to accurately spray at the exact required locations.
There are nozzles every 25cm on the sprayer boom and each nozzle can dose independently and quickly as the machine moves along the paddock, thanks to fast-switching nozzles that switches on and off 100 times per second.
The end result was a stunning 132x200m painting of the Mona Lisa, in the snow, making it one of the largest versions of the famous painting in the world.
Agrifac reported it used approximately 1635 litres of dye to "paint" the gigantic portrait, proving that blanket spraying a paddock in the present day is so passé. Not to mention expensive.
