Resumen:
Araujia hortorum E. Fourn. is native to South America, where it is a valued species. In contrast, in otherparts of the world where it was introduced as an ornamental, it has become an invasive weed. In NewZealand, it has been targeted for biological control, and this motivated field surveys for fungal pathogensin its native range in Argentina. The etiology of a frequently encountered disease was studied. Affectedplants showed round necrotic leaf spots, and sometimes defoliation. Pathogenicity tests were conducted,and Koch?s postulates were completed. Ascochyta araujiae Speg. was identified as the causal agent.Through inoculation tests conducted on other species within the Apocynaceae it was shown that thispathogen is not highly specific. All five non-target species tested were found to be susceptible to thedisease.
