The Pieton air / liquid spray technology was developed by the Van der Ende Groep over 10 years ago. So far it has been mainly applied in crops such as roses and gerberas, which is harder to have an effective way of spraying. This spraying technique should not be compared with spraying with air support. The main difference is that the air is mixed with the liquid before it exits the nozzles, which therefore creates a powerful targeted spray mist. By adding air pressure to the fluid pressure, the droplets have a high speed (kinetic energy) at the time the fluid pressure is still low, that way it can penetrate deep into the crop without too much air movement.
For testing at GreenQ Improvement Centre, the nozzles have been placed off center, which increases the distance to the crop. This provides an optimal distribution of the spray liquid in the crop.
The advantages of the air / liquid (Pieton) syringes are:
- • Very high penetration
- • Droplet size and fluid delivery adjustable
- • Highly effective control
- • Less frequent spraying
- • Savings on pesticides
The Pieton spraying robot will be tested in various crops under the guidance of GreenQ’s greenhouse manager Rick van der Burg for the coming weeks. The goal is to determine the best air / liquid ratio. The first spraying round was very satisfying for Rick. He saw lots of little droplets on and under the leaves and no big drops.
