Industry-led WeedSmart program has provided insight into how wheat and canola crops offer growers practical options to improve crop competition against weeds, particularly grasses, and vastly reduce weed seed set.
It has detailed how University of Adelaide researchers, led by Dr Chris Preston and with Grains Research Development Corporation investment, took part in an extensive study to identify the agronomic factors that promoted strong early crop growth.
They found that simple strategies of growing hybrid canola and sowing wheat early could couple with pre-emergent herbicides to achieve an effective double-knock.
The result is more yield, less weed seed produced and less selection pressure on the herbicides.
