Shift your thinking to PRE-EM broadleaf weed management.

Broadleaf weed control has – until now – relied heavily on post-emergent herbicide programs.

CALLISTO® is a powerful Group H pre-emergent herbicide that allows growers to control broadleaf weeds in wheat and barley as part of an integrated weed control strategy.

Group H chemistry used pre-emergent in cereals is a unique use pattern, that has been tested and shown to exhibit excellent broadleaf weed control, in addition to excellent crop safety in over 80 replicated trials across Australia.

Use CALLISTO as a key part of your broadleaf weed strategy, and stop broadleaf weeds before they start.

Please note: CALLISTO is not yet registered. An application is under evaluation by the APVMA
