Abstract
In laboratory experiments strains ofCladosporium cucumerinum andFusarium oxysporum f.sp.narcissi were selected, which showed resistance to the fungicidal antibiotic pimaricin. Increased resistance appeared associated with decreased fitness in vitro (radial growth and sporulation on agar media) and in vivo (pathogenicity). The physiological background of a link between sensitivity to the fungicide and pathogenicity is discussed.
Samenvatting
In laboratoriumproeven werden stammen vanCladosporium cucumerinum enFusarium oxysporum f.sp.narcissi verkregen, die resistent waren tegen het fungicide antibioticum pimaricine. Toegenomen resistentie bleek gepaard te gaan met een verminderde vitaliteit in vitro (radiale groei en sporulatie op een agar voedingsbodem) en in vivo (pathogeniteit) (Tabel 1 en 2). Het niveau van de resistentie tegen pimaricine bleek erg beperkt (Fig. 1). De fysiologische achtergrond van een koppeling tussen gevoeligheid voor het fungicide en pathogeniteit wordt besproken.
