Blanket and point-to-point, on one airframe
Mist is short for Mobile Intelligent Sustainable Tech. The range covers blanket spraying across open ground and point-to-point application where only part of a block needs treating, which is the difference between covering a paddy field and treating individual trees.
Spray pressure, droplet size and volume are all adjustable through interchangeable nozzles. That is the mechanism behind the usual claim about reducing chemical use: material goes where it is needed, at the rate it is needed, rather than uniformly across everything.
The second reason estates move to drone spraying is exposure. Nobody walks a treated block with a backpack sprayer.
