Studies by Alberta Agriculture crop pathologist Michael Harding, which compared different disinfectants that can be used on farm equipment, showed a 50:50 concentration of common household bleach and water killed spores and is cheaper.

Nothing fancy about killing clubroot

An Alberta study has shown that household bleach works as well as specialized disinfectants

Canola program stacks genes against new clubroot

Rather than send out a canola variety with a single source of resistance against clubroot — especially the disease’s most recent pathotype — Agrium’s CPS division has stacked several sources into the new hybrids it’s sending for testing this summer.

Clubroots beating all resistant canolas across Alta.

A study of 27 canola fields across Alberta has found 16 infected with clubroot pathotypes able to cause “high levels” of the disease — in canola plants with clubroot-resistant genetics. What’s more, the clubroot pathogen isolated from “many” of the infected fields in the study was virulent on all clubroot-resistant canola cultivars, the Canola Council of Canada […] Read more
