Potential clubroot control shows promise in the lab

The next phase is greenhouse testing followed by field trials

Saskatoon-based MustGrow Biologics Corp. is working on a product derived from mustard seed it says will potentially control clubroot, a yield-robbing canola disease currently without chemical control. It has infected thousands of acres in Alberta and is spreading in Saskatchewan and Manitoba. “In the lab we are seeing 100 per cent control (of clubroot spores),” MustGrow’s chief operating officer Colin

Soybean cyst nematode confirmation presents challenge for producers

Pests like soybean cyst nematode and clubroot are present and rising in Manitoba fields, but the steps to prevent both of those pests are largely the same

Farmers are being urged to keep equipment clean after the confirmation of yet another soil-borne crop threat in the province. Farmers got the unfortunate, but not unexpected, news that soybean cyst nematode (SCN) infections have been confirmed in four municipalities Sept. 16.

Clubroot spores infect canola roots and produce galls that prevent plants for taking up moisture and nutrients.

What does the new resistance-evading clubroot mean for Manitoba canola growers?

A new clubroot strain not controlled by canola varieties with traditional 
resistance genes has been found in Manitoba, but farmers can still keep this 
potentially devastating in check by being proactive

The discovery in south-central Manitoba of a new clubroot strain not controlled by traditional resistant canola varieties underscores the need to be proactive in keeping clubroot spore numbers low enough so they don’t damage canola crops. The 3A clubroot pathotype was found in a field in the RM of Pembina, Manitoba Agriculture posted on its

Clubroot affects all cruciferous plants – not just canola (seen here) – which includes brassica oilseeds such as mustard.

Organic farmers don’t get a pass on clubroot

Clubroot can also infect mustard, radish and other brassicas

Organic farmers are mistaken if they think they will be spared from the clubroot infestation making its way across the Prairies because they don’t grow canola, a crops extension specialist with Saskatchewan Agriculture says. Brent Flaten warned growers attending the SaskOrganics annual conference March 29 the disease affects all cruciferous plants, and that includes brassica
