Resistance to pydiflumetofen in <i>Botrytis cinerea</i>: risk assessment and detection of point mutations in <i>sdh</i> genes that confer resistance

Abstract

The fitness was significantly higher for all pydiflumetofen-resistant mutants than the corresponding parental. Two types of point mutations, sdhB-P225L and sdhC-G85A and I93V, might confer resistance to pydiflumetofen in B. cinerea. A precautionary resistance management strategy should be implemented. © 2021 Society of Chemical Industry.
