Molecular characterization of boscalid‐ and penthiopyrad‐resistant isolates of <i>Didymella bryoniae</i> and assessment of their sensitivity to fluopyram

Abstract

The genotype-specific cross-resistance relationships between the SDHIs boscalid and penthiopyrad and the lack of cross-resistance between these fungicides and fluopyram should be taken into account when selecting SDHIs for gummy stem blight management.
