Drift Reduction Measures - Micron Spraydome Series Instruction Manual

2.4.1 Drift Reduction Measures

The Spraydome/Undavina/Spraymiser units are fitted with shields low to the ground
making them far less susceptible to spray drift than unshielded spray nozzles.
Wind tunnel studies in the UK have indicated drift reductions in excess of 90% over
conventional unshielded sprayers and the Enviro range of covered spray shields are
suitable as a Drift Reducing Technology (DRT)
Below are UK star ratings for drift reduction with the Undavina, Spraydome and
Spraymiser. LERAP (Local Environmental Risk Assessment for Pesticides)
Note: The maximum drift reduction of >75% receives 3 star rating.

Table 1 – LERAP Drift reduction rating (2 m/sec wind speed)
Spray heads must always maintain close contact with the ground. When operating
on uneven or rough ground reduce speed to ensure the spray heads do not bounce.
The following measures may be used to further reduce any risk of spray drift.
 Schedule treatment for the early morning or the evening hours (there is generally
less wind).
 With the Hi Flo units avoid spraying at pressures above 30 psi (2 bar) where
possible.
 Keep the working height of the spray heads as low as possible. The risk of drifting
increases as the distance between the shield and ground increases.
 Avoid operating at excessive speeds and flow rates.
