N2 - Fungicides are valuable tools for crop protection, and correct use reduces the risks associated with fungal plant diseases, especially those related to yield losses. On the other hand, excessive fungicide use can give rise to the selection of fungicide-resistant pathogens (Brent and Hollomon 2007). Quinone outside inhibitor (QoI) fungicides have been widely used to manage plant diseases, because they have a broad spectrum against many fungal plant pathogens. Fungicides in the QoI class inhibit mitochondrial respiration by binding to the quinol oxidation site of the cytochrome bc1 complex, interrupting electron transport (Bartlett et al. 2002). Because QoI fungicides have a single mode of action, the risk of selection of fungal isolates with resistance is considered high (FRAC 2020).
