Check patches of prematurely ripening canola for signs up disease. Dig up roots to check for clubroot galls. Early infection at the seedling stage can result in wilting, stunting, yellowing and even death of canola plants in the late rosette to early podding stage…

Those same moist fields that have delayed spring harvest as well as seeding in central Alberta (and some other regions) also mean more mud clinging to equipment. More mud means more clubroot spores riding along on tires and equipment frames. Though the time crunch is on, knocking off as much mud as possible will reduce clubroot spread. In these conditions,…

Make sure soil is cleaned off any used equipment recently purchased from areas known to have clubroot. This is good biosecurity practice. Ideally, this should be done at the purchase location before bringing it home…

We know that tillage will spread clubroot as well as weed seeds and verticillium, but ruts can create headaches for combining, fall spraying and seeding next spring. Working wet fields can also cause compaction…

Keep a look out for clubroot, and take care to slow the spread of soil away from these infested areas. This quiz gives you a few numbers to think about…

More than 10 clubroot pathotypes have been identified in Alberta, and clubroot-resistant (CR) varieties will not protect against all of them. CR varieties with the same source of resistance grown in a short rotation will quickly select for those pathotypes that are virulent to those varieties. With good moisture for clubroot this year, many fields of CR canola are showing…

CR varieties deployed now to keep clubroot levels low is part of a long-term management approach to keep clubroot from ever reaching yield-damaging levels. CR varieties are recommended if growers are in communities where or near where clubroot is known to exist AND they…
