摘要

2023年11月，在墨西哥锡那罗亚州Culiacán的一块商业地里，在覆盆子植物上发现了叶子变黄和枯萎的症状，以及树冠和根腐病。在分离出具有卵菌特征的菌落后，对两个分离株进行了纯化。通过形态学检查、致病性测试以及利用ITS和LSU序列数据进行系统发育分析，确定致病因子为helicoides Abad、De Cock、Bala、Robideau、Lodhi和Levesque。这是国际上首次报道的引起覆盆子冠腐病和根腐病的螺旋螺旋体。

First report of Phytopythium helicoides causing crown and root rot of raspberry (Rubus Idaeus L.) in Mexico

In November 2023, symptoms of leaf yellowing and wilting, as well as crown and root rot, were detected on raspberry plants in a commercial field located in Culiacán, Sinaloa, Mexico. Following the isolation of colonies displaying oomycete characteristics, two isolates were purified. Through a combination of morphological examinations, pathogenicity tests, and phylogenetic analysis using ITS and LSU sequence data, the causal agent was identified as Phytopythium helicoides Abad, De Cock, Bala, Robideau, Lodhi & Levesque. This is the first report of P. helicoides causing crown and root rot of raspberry worldwide.
