Abstract

Leaf blight was detected on potted blood lily (Scadoxus multiflorus) plants in a garden located in Andhra Pradesh, India. Pycnidia resembling a Lasiodiplodia species were consistently detected on the foliage of symptomatic plants. Based on morphology, cultural features and molecular analysis, the species was identified as Lasiodiplodia theobromae. Koch's postulates were fulfilled by pathogenicity tests carried out on potted blood lily plants. To the best of our knowledge, this is the first report of the occurrence of a disease caused by L. theobromae on S. multiflorus.

印度首次报告由 Lasiodiplodia theobromae 引起的血百合（Scadoxus multiflorus）叶枯病

在印度安得拉邦的一个花园中，盆栽血百合（Scadoxus multiflorus）植物上发现了叶枯病。在有症状植物的叶片上持续发现了类似 Lasiodiplodia 物种的菌丝。根据形态学、文化特征和分子分析，确定该物种为 Lasiodiplodia theobromae。在盆栽血百合植物上进行的致病性试验证实了科赫假设。据我们所知，这是第一份由 L. theobromae 在多花睡莲上引起病害的报告。

期刊介绍： Journal of Phytopathology publishes original and review articles on all scientific aspects of applied phytopathology in agricultural and horticultural crops. Preference is given to contributions improving our understanding of the biotic and abiotic determinants of plant diseases, including epidemics and damage potential, as a basis for innovative disease management, modelling and forecasting. This includes practical aspects and the development of methods for disease diagnosis as well as infection bioassays. Studies at the population, organism, physiological, biochemical and molecular genetic level are welcome. The journal scope comprises the pathology and epidemiology of plant diseases caused by microbial pathogens, viruses and nematodes. Accepted papers should advance our conceptual knowledge of plant diseases, rather than presenting descriptive or screening data unrelated to phytopathological mechanisms or functions. Results from unrepeated experimental conditions or data with no or inappropriate statistical processing will not be considered. Authors are encouraged to look at past issues to ensure adherence to the standards of the journal.
