The Hart Field-Site Group has been running a SAGIT-funded trial looking at the efficacy of herbicides in different stubble heights and at different volumes. As part of this, it recently hosted spray guru Bill Gordon to lead a grower workshop.

SAGIT captured this short video explaining the trial and how growers can use simple tools as a cost-effective trial before spraying.

Bill has written a GRDC Grow Note (technical manual) on spray application, which includes details on the cards and how to use them.
