title: Dominance relationships of bean pathogens at Lake Balaton.
abstract: Dominance relationships of different bean pathogens were examined during 1999-2000 in small plot trials at Lake Balaton in Hungary. In 1999 the dominant pathogen species were Xanthomonas campestris pv. phaseoli. The main cause of the stock decay was due to the infection of Fusarium spp. Bean plants were infected also by Alternaria, Colletotrichum, Macrophomina and Sclerotinia, species part from viruses. Among of thirty-eight examined bean cultivars and genotypes the variety "Díszbab" and the genotype 513 were the most resistant. In 2000 Macrophomina phaseolina and Fusarium spp. caused epidemics. Most of the observed plants died early. The most healthy species and branches were the SC-34-1 and cv. Díszbab.
