How does a low drift nozzle work?

• It is a flat fan nozzle where an internal
venturi creates negative pressure inside
the nozzle body.
• This creates larger droplets that contain
small bubbles of air.
• The droplet is classified as a Coarse
Spray, as defined by the BCPC system.
• The coarser droplet enables the spray to
travel accurately from nozzle to target.
• On impact the bubble bursts leaving
smaller droplets across the leaf for
absorption.

Corteva Agriscience support the use of
low drift nozzles for the application of our
grassland herbicides and a water volume
down to 200 litres/ha.

We encourage their use for the following
reasons:
• Less drift (up to 75% reduction).
• Reducing spray drift is a requirement of the
Plant Protection Products
(Sustainable Use) Regulations 2012.
• Reduced buffer zone if 3 Star rating
achieved.
