Canola gives us a good phase to clean up broadleaves, usually, so I tend to leave CALLISTO® to barley…
It is quite tricky getting good weed control options for oats and barley.
”
Excellent tank mix compatibility, outstanding efficacy…
Broad spectrum of weed control and consistent performance under dry sowing, CALLISTO® is a good all-rounder.

You can throw it in early (dry) to get on with the other jobs, and you’re not coming back with a product when it’s too wet or too dry, or dodging weather.
CALLISTO® buys you time.
”
Dropping out Diuron*, the residual 8–12 weeks with CALLISTO® has been awesome as busy mixed farmers, having longer to apply an in-crop herbicide.
”
In those paddocks where we used CALLISTO® the [volunteer] canola has still come up, but it was real sick, pale and bleached.
It was enough to get the barley going.
