Blackleg Pathogens of Canola - New Advances In Control and Resistance.

Research in Blackleg in canola has advanced a lot since the last Canola Research Conference. At the same time, the pathogen has become a major problem in canola growing regions in the US, especially in North Dakota and some of the Great Plains States. Several farmers have reported unusually high incidence of the disease in their fields. This is true for Canada as well. The understanding we have of the pathogen races in North America (not particularly pathogenicity groups), the number of R-genes involved in canola varieties with regards to blackleg are worthy of mentioning. U of Manitoba has also cloned one of the R-genes, a first in canola-blackleg research in the world. This paper will assist the US and other Canola industrys of the recent developments in the situation with the disease in the canola growing regions, research advancements, trade barriers due to blackleg and what is been done to overcome these issues at the research and industry level.
