“…For MBCs, plant pathogens, such as Botrytis cinerea , 195,196 Monilinia fructicola , 205 Monilinia laxa , 207 and Ustilaginoidea virens , 212 exhibit fitness costs linked to E198A/V/K, F200Y, L240F, and M233I mutations in the β‐tubulin gene (Table 3). No fitness costs associated with MBC resistance have been found in Botryosphaeria dothidea , 193 Botrytis cinerea , 21 Colletotrichum musae , 199,200 Monilinia fructicola , 179,206 Oculimacula sp., 208 Phomopsis obscurans , 142 and Pseudocercosporella fijienses 211 (Table 3).…”

BackgroundFungicides are indispensable for high‐quality crops, but the rapid emergence and evolution of fungicide resistance have become the most important issues in modern agriculture. Hence, the sustainability and profitability of agricultural production have been challenged due to the limited number of fungicide chemical classes. Resistance to site‐specific fungicides has principally been linked to target and non‐target site mechanisms. These mechanisms change the structure or expression level, affecting fungicide efficacy and resulting in different and varying resistance levels.ResultsThis review provides background information about fungicide resistance mechanisms and their implications for developing anti‐resistance strategies in plant pathogens. Here, our purpose was to review changes at the target and non‐target sites of quinone outside inhibitor fungicides (QoIs), methyl‐benzimidazole fungicides (MBCs), demethylation inhibitor fungicides (DMIs), and succinate dehydrogenase inhibitor fungicides (SDHIs) and to evaluate if they may also be associated with a fitness cost on crop pathogen populations.ConclusionThe current knowledge suggests that understanding fungicide resistance mechanisms can facilitate resistance monitoring and assist in developing anti‐resistance strategies and new fungicide molecules to help solve this issue.This article is protected by copyright.
