Avirulence management has been used for disease control in various crops, particularly against powdery mildew and rusts of cereals. New research is providing information on the population structure of Leptosphaeria maculans in different regions and the resistance genes present in the host crop, enabling diversification in canola planting to reduce the risk of epidemics occurring
and delay the breakdown of single gene resistance. Integration of avirulence management with cultural practices that reduce disease severity and therefore reduce inoculum production for the following season, is important to enhance the level of control achieved and prolong resistance. This paper summarises recent research relating to this issue with an emphasis on the situation
in western Europe, but many of the factors discussed also apply to other regions. The review draws extensively on papers presented at the stem canker durable resistance workshop, September 2004, INRA-Versailles, France.
