With the rapid emergence of resistance to the limited number of fungicide classes in many pathogenic fungi, improving stewardship of extant fungicides is a priority. Resistance management strategies, species identification, application timing and delivery of FRAC guidelines to stakeholders can all affect the manner of using fungicides. This chapter describes the evolution of fungicide resistance and examines ways of monitoring the development of resistance to fungicides. The chapter emphasizes the importance of species identification in disease management, and examines the adoption of decision-support tools to improve fungicide efficacy. Finally, the chapter looks ahead to future research trends in this area.
