Brown spot needle blight, caused by Lecanosticta acicola, is a serious disease of pines worldwide and has become of great concern in Europe over the last decade, with significantly increased outbreaks in pine forests. We examined native and non‐native Pinaceae taxa (four Cedrus and 24 Pinus) in the Atatürk Arboretum, Istanbul, Turkey, for the presence of L. acicola. Needles were sampled from 37 trees at least twice between March 2017 and July 2018. Symptomatic occurrence of the disease was confirmed by isolations, followed by molecular identification via sequencing of the ITS region. Lecanosticta acicola was isolated from symptomatic needles of 10 trees from seven host taxa (Cedrus and six Pinus). Molecular diagnostics of isolates confirmed the identification of L. acicola on Cedrus libani, Pinus sylvestris, P. nigra subsp. nigra, P. nigra subsp. laricio, P. nigra subsp. pallasiana, P. nigra subsp. pallasiana var. fastigiata and P. nigra subsp. pallasiana var. pallasiana f. şeneriana in the arboretum.

Lecanosticta acicola在土耳其松树和非松树寄主上的首次报道

由Lecanosticta acicola引起的褐斑病，是世界范围内的一种严重的松树病，在过去的十年中，欧洲引起了人们的极大关注，松树林的暴发大大增加了。我们检查了本地和非本地松科植物类群（4个雪松和24名松在阿塔图尔克植物园，伊斯坦布尔，土耳其），对存在L.褐斑病。在2017年3月至2018年7月之间，从37棵树上至少两次采样了针叶。通过分离确认该病的症状发生，然后通过ITS区测序进行分子鉴定。松针褐斑病从的七个主机类群10种树木对症针（隔绝雪松和六个Pinus）。分离物的分子诊断证实了L. acicola在雪松，樟子松，黑质亚种中的鉴定。黑，欧洲黑杨亚种。laricio，欧洲黑杨亚种。pallasiana，黑体育亚种。pallasiana变种。fastigiata和黑体育。pallasiana变种。pallasiana f。şeneriana在植物园中。
