Dia symptoms were collected on two to 22 sampling dates per plot between 2000 and 2002. Four multiallelic microsatellite markers were ud for genotypic identification of pathogen sa
mples. Genetic analysis showed more than 2300 site-specific P. viticola genotypes, indicating that populations are genetically rich demographic units. Approximately 70% of the genotypes were sampled once and 14% were sampled twice throughout the various epidemics. In the 18 populations only ven genotypes (0.3%) were identified more than 50 times. Three genotypes particularly successful in causing dia through condary cycles showed mainly
