In 2009 on Begonia semperflorens stem base, brown conical spots spreading upwards to the first branching were observed. Affected plants wilted slowly and died. From diseased tissues Phytophthora cactorum was mainly isolated. Botrytis cinerea, Fusarium avenaceum and F. culmorum occurred only sporadically. In laboratory trials P. cactorum colonized leaves of Begonia semperflorens and Begonia × hybrida with significantly faster development of necroses on the first species. Among 4 cultivars of begonia significantly faster colonization of leaf petioles was observed on Willem Kusters. In greenhouse trial the pathogen colonized leaves and stems of B. sempervirens.
