Clubroot on canola was regular and more prevalent than expected in Cavalier County in the current survey. Prevalence of clubroot on canola has been increasing at rapid pace in North Dakota and has been confirmed in 33 fields in Cavalier County in 2018, which is five times more than it was in 2017. Contrastingly, no clubroot positives were found in any other canola growing counties of North Dakota that were surveyed. Continuous survey in coming years is needed to prevent the spread and to design management plan of clubroot along with extensive outreach activities throughout North Dakota to educate growers in identifying clubroot disease, the biology of the pathogen, its spread and prevention.

Survey reports of clubroot in Alberta and Manitoba provinces of Canada confirmed over 3000 and 600 canola fields respectively were clubroot positives (Strelkov, 2018. Personnel communication at Clubroot International workshop). Spread of clubroot can be reduced by thorough sanitation and through adopting integrated disease management consisting disease resistant cultivars, longer crop rotations, and soil reclamation (Donald and Porter 2009). Extensive crop survey, determination of soil pH of canola fields with clubroot was found to be an important arsenal in educating growers about the prevalence of clubroot in North Dakota on Canola. The prevalence data will be more fruitful when integrated with other available clubroot management practices. Survey and prevalence data can be used in outreach activities to educate producers in identifying the disease, inform of potential risks and to encourage clubroot monitoring and adoption of sanitation practices. Removal of potentially contaminated soil from field equipment is an ideal one if practiced (Strelkov et al. 2011). Likewise, length of crop rotation with canola can be determined with the knowledge of detection of clubroot in a field. Finally, clubroot on canola may be more prevalent than expected in North Dakota. Catching it early and being proactive is crucial to manage such a yield robbing and difficult to control disease. Likewise, extensive research needed to develop a better understanding of clubroot risk and its management in canola in North Dakota conditions.
