The South American vine (Apocynaceae) was introduced as an ornamental species in several countries and has since become an invasive weed in many of them. In New Zealand it has been targeted for classical biological control, and this motivated field surveys for fungal pathogens in its native range in Argentina. A disease was frequently encountered in the field causing extensive damage to foliage, as well as stems and fruits. The fungus found in association with the symptoms was identified as . A detailed description of the fungus and the disease is provided. Pathogenicity tests were conducted, and Koch's postulates fulfilled. Host range tests were conducted on species within the Apocynaceae. Four of these, belonging to the same subtribe as , were found to be susceptible to the disease, while others less related ones were not. was observed to be able to cause severe disease on its host and to be highly specific. It is therefore proposed as a potential biological control agent against in New Zealand.
这种南美洲藤本植物（夹竹桃科）作为观赏物种被引入多个国家，此后在其中许多国家成为入侵杂草。在新西兰，它已成为经典生物防治的目标，这促使人们对其在阿根廷的原生地进行真菌病原体的实地调查。在田间经常遇到一种病害，对叶片、茎和果实造成广泛损害。与这些症状相关联发现的真菌被鉴定为……。提供了该真菌和病害的详细描述。进行了致病性测试，并满足了科赫法则。对夹竹桃科内的物种进行了寄主范围测试。其中四种与……属于同一亚族的物种被发现易受该病害影响，而其他关系较远的物种则不易感。……被观察到能够在其寄主上引发严重病害且具有高度特异性。因此，它被提议作为新西兰针对……的潜在生物防治剂。
