How it Works
Proline 480 is a broad spectrum, systemic fungicide for the control or suppression of listed diseases on registered
crops.
Application Tips
When used in wheat barley and oat apply with a non-ionic surfactant (AgSurf or Agral 90) at 0.125% v/v.
Spray coverage is essential for optimum efficacy. Spray equipment must be set up to provide good coverage to wheat
and barley heads. Nozzles should be operated within the spray pressure recommendations suggested by the
manufacturer.

Pre-harvest interval
:
Barley, wheat and oat - 30 days; canola, flax, rapeseed or oriental mustard - 36 days; chickpeas

Re-entry
:
Do not re-enter treated fields until 24 hours post-application.
Re-cropping
:
Treated areas may be replanted with any crop specified on the label as soon as practical after the last
