There are varying opinions on how to control Roundup Ready canola that sprouts up in Roundup Ready soybeans.
Joe Vink, Weed Management Technical Lead with Monsanto Canada says there are three easy steps to get the job done.
"The first step is if you plan to till after harvesting canola, just delay that tillage," he said. "And if you do till, till it very shallow. So when you delay tillage you just allow that canola that was lost at harvest to germinate at the surface and either it's controlled by tillage later on...or if you don't till it's exposed to winter elements."
Vink says producers should consider adding a cereal or corn crop the year after canola is grown. He suggests spring wheat is good competition and that herbicides used in cereals are really good at controlling roundup ready canola.
Finally in the third year, Vink says field conditions should be ok to plant Roundup Ready soybeans. He notes there are a few different herbicide options that are available if volunteer canola starts to become a problem.
