Introduction 9
Micron Sprayers Ltd. Spraydome/Undavina and Spraymiser
1 INTRODUCTION
The Spraydome/Undavina/Spraymiser is designed for the precision application of
sprays. The spray heads are shielded to protect spray from drift. The shielded spray
heads incorporate either low volume rotary atomisers for controlled droplet
application (CDA) or traditional hydraulic pressure nozzles. The shielded spray heads
are designed primarily for the application of herbicides in beds. The shielded spray
heads can also be used to apply non selective herbicides in the crop inter-row or
around trees at reduced dose rates and volumes as only a proportion of the area is
treaded.
The Undavina and Spraydome sprayers are mounted on a breakaway arm which
allows the shield to rotate on a centre bearing and roll around tree or bush crops.
