Abstract excerpt

BACKGROUND: Grape anthracnose caused by the ascomycete fungus Colletotrichum gloeosporioides has been widely controlled by demethylation inhibitors (DMIs) for decades in China. The resistance status and mechanism of C. gloeosporioides against DMIs is not well understood. RESULTS: All difenoconazole-resistant (DfnR ) isolates from vineyards exhibited decreased fitness. Positive cross-resistance was detected...
