Using the right weed control products, he suggests it is possible to grow both Roundup Ready crops — ideally, with corn planted prior to canola in a rotation.

In addition to problems with weed control, following Roundup Ready canola can also create challenges with phosphate availability for corn, notes McKinnon.

He spoke with Shaun Haney as part of the Monsanto Momentum Tour stop in Carseland, Alberta:
