1. Nozzles and Drift Reduction
Presentation GROUP D

2. Questions 1. Reasons of drift reduction
2. Measures for drift reduction
3. Relationship between drift reduction and nozzles

3. Video presentation Explanation of the code of the nozzles
Top edge of the nozzles
Low drift nozzles
Influence of the pressure
Influence of the high of the boom on the drift
Constant efficiency of the nozzles
Identification of the problems with the nozzles

4. Identification based on colour and the code on the nozzle
Code of the nozzles
Identification based on colour and the code on the nozzle
Pressure 3 bar/min
Yellow – 0,2 l/min
Blue - 0,3 l/min
Red – 0,4 l/min
Grey – 0,6 l/min

5. Top edge of the nozzles
Correlation between top edge and height of the boom
Example:
80o (80 cm) o (50 cm)
Dependance on crop height

6. Low drift nozzles Mixing air with fluid Bigger drops
Transporting drops on the crop (target) by air
Colour based coding

7. Influence of the pressure
Higher pressure – smaller drops – more drift
Lower pressure – bigger drops
– less drift

8. Constant efficiency of the nozzles
Constant flow rate
Constant cone
Constant low drift level and constant concentration applied on target

9. Identification of the problems with the nozzles
Problems with pressure (pulses)
Problems with nozzles (individual nozzles give different flow rate and cone)

10. Profit of low drift
Best efficacy (less money for treatment, less losses of PPPs)
Human health protection (near residential areas, bystandards, workers)
Evironment Protection (water sources, non target organisms (bees, non target plants, non target animals)

11. if it is raining outside when
Conclusion
It doesn´t matter
if it is raining outside when
you have good umbrella
