While many fungicides are effective disease management tools, management with some fungicides is problematic, with fungicide resistance being an important limitation. Fungicide resistance or tolerance has been reported in C. beticola for several fungicides classes, including the benzimidazoles, organotins, and sterol demethylation inhibiting fungicides. While resistance has been reported to these classes, the genetics of this resistance has not been well studied. This chapter examines what is currently known about the genetics of fungicide resistance in Cercospora, and what has been determined in other ascomycetes and might be occurring in C. beticola as well.
