SummaryThe presence of Ascochyta phaseolorum as a pathogen of Phaseolus vulgaris in Queensland is reported. The fungus has been found to have a wide host range including vegetable crops, pastures, weeds, and indigenous species. Natural infections were found in 48 hosts in 14 families, and an additional 12 species proved susceptible when inoculated experimentally. Pathogenicity of isolates from French bean towards many of the natural hosts has been demonstrated, and in reciprocal inoculations cultures from field·infected hosts produced symptoms on bean typical of those produced by bean isolates. The fungus is shown to be a weak parasite, requiring some form of wounding to initiate infection under Queensland conditions.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
