Rijkers, J. Hiemstra, G. Bollen] Under young ash trees infected withVerticillium dahliae, over 10% of the petioles of fallen leaves were colonized by the pathogen. Counts of microsclerotia in six petioles yielded an average number of 1500 per cm of petiole. Windblown leaves from infected trees very probably contribute to dissemination of the pathogen in forest stands and nurseries. Koninklijke Nederlandse Planteziektenkundige Vereniging, 1992 Rijkers A.
