A second case of clubroot has been reported in the RM of Lorne this year.

Holly Derksen, field crop pathologist with Manitoba Agriculture, believes increased awareness has inspired growers to scout their fields for the disease and feels this has led to more reports.

She encourages growers to scout any areas in their canola fields where the crop is under-performing.

"Typically it's at approaches, low-lying areas, fence lines or tree lines, or any patches in your field that you think are under-performing. Even if you think you know it's because of a saline issue or compaction, we just want people double-checking and pulling up plants."

Derksen cautioned that the clubroot bulb starts to decay at this time of year, making it harder to pull out the plant and get the whole thing. She suggests using a shovel to help get the job done.

If growers suspect clubroot in their fields, Derksen encourages them to talk to their local Manitoba Agriculture office, at which point someone will come out to confirm the case and work with them on a management plan.
