New fungicide active substances are at risk of losing efficacy due to the development of resistance in target pathogen populations. In the European Union, an assessment of resistance risk is required by regulatory authorities for the approval of each fungicide product This chapter will review the development and scientific rationale of the widely used risk matrix approach to fungicide resistance risk assessment. This type of approach relies on previous experience of resistance with a particular fungicide mode of action, pathogen and agronomic system to assess the level of risk. A more recent trait-based approach that doesn’t rely on prior knowledge will also be reviewed. Finally, this chapter will consider future trends in fungicide resistance risk assessment.
