Nozzles and Drift Reduction Presentation GROUP D

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

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

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

Top edge of the nozzles Correlation between top edge and height of the boom Example: 80o (80 cm) 110o (50 cm) Dependance on crop height

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

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

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

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

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)

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