Are ‘pre-ems and crop competition’ the ‘wine and cheese’ of weed control in canola?

Wine and cheese. Strawberries and cream. Crop competition and pre-emergent herbicides.

Ok so the last one doesn’t quite have the same ring about it but they really do go together nicely. Combining a competitive canola variety with pre-emergent herbicides has proven to be an effective strategy for reducing annual ryegrass seed set.

Recent trials showed that with effective pre-emergent herbicides, a competitive hybrid canola variety can reduce ryegrass seed set by 50% compared with a less competitive open-pollinated (OP) variety.

That’s impressive. But should we tar all OP varieties with the same brush?

Chickpeas can compete

There are few herbicide options for sowthistle control in chickpea crops, making the perfect recipe for a good ol’ sowthistle blowout. Despite all of this, the latest research by Michael Widderick, Adam McKiernan and Greg Harvey from QDAF with GRDC investment is finding that chickpeas can win the competition against sowthistle if they stack their deck. Growing a chickpea crop at narrow row spacing and high crop density in northern cropping regions can greatly reduce sowthistle seed production without reducing chickpea yield.

How a new wheat variety could compete with weeds like Jonah Lomu did on the field

Jonah Lomu stood at 6’5”, weighed 120kg, and ran the 100m in a lazy 10.7 seconds. He could play the power game, the speed game, and he could step. He was the ultimate competitor. Mace wheat, on the other hand, is agile, dependable, and can play the yield game, but its ability to compete with weeds is limited. However, yield is king, and hence Mace has been an extremely successful variety where weeds are under adequate control. What if we could have a wheat variety that could play the yield game and the competition game? What would that look like?
