Abstract
AbstractThe ring‐substituted N‐phenylanilines, N‐(3‐chlorophenyl)aniline (MC‐1) and N‐(3,5‐dichlorophenyl)aniline (MC‐2) were tested for their antifungal activity against Botrytis cinerea Pers. ex Fr. and Venturia nashicola Tanaka et Yamamoto. In both fungi, increased sensitivity to MC‐1 and MC‐2 was clearly observed in ‘highly carbendazim‐resistant, diethofencarb‐sensitive’ (HR, S) phenotypes. Sensitivity was low in ‘carbendazim‐sensitive, diethofencarb‐resistant’ (S, R) and ‘intermediately carbendazim‐resistant, diethofencarb‐resistant’ (IR, R) strains. On cucumber cotyledons, other strains of B. cinerea, possessing the phenotype ‘highly carbendazim‐resistant, diethofencarb‐resistant’ (HR, R) were not controlled by either MC‐1 or MC‐2. Response to MC‐2 was also examined using random ascospore progenies from V. nashicola crosses. In these progenies, high‐level carbendazim resistance and MC‐2 sensitivity always segregated together. Sensitivity to MC‐2 is controlled by a single gene which is either identical to or very closely linked to one conferring high‐level resistance to carbendazim.
