隔孢壳座菌（Dothistroma septosporum）是一种引起松树针叶枯病（Dothistroma needle blight，DNB）的病原真菌，最近开始影响英国的苏格兰松（ScotsPine）林地。除了造林方法外，对森林苗木喷洒杀菌剂也有助于防止DNB的传播。然而，现代单位点杀真菌剂对D. septosporum的有效性和杀真菌剂抗性进化的风险在很大程度上仍然未知。在这个项目中，我们的目的是建立D. septosporum在体外对一些广泛使用的单点杀菌剂类别的敏感性，并确定是否已经存在杀菌剂抗性，因为这可能会增加D. septosporum基因型在天然林地种植股票上的传播。为此，我们比较了分离物ofD. septosporum，来自松树林未暴露于杀菌剂，从苗圃爆发的菌株，一系列常用的杀菌剂的敏感性。我们测试的大多数杀菌剂在体外是有效的，我们没有观察到在森林苗圃敏感性的显着变化。虽然需要进一步的植物试验来确认单点杀菌剂对D.septosporum的有效性，但我们的研究结果表明，它们可以成功地用于DNB控制，尽管强烈建议采取适当的措施来防止杀菌剂抗性的演变。
Dothistroma septosporum, a causal agent of Dothistroma needle blight (DNB), is a damaging fungal pathogen of pines that has recently started to affect native Scots pine woodlands in the UK. In addition to silvicultural methods, fungicide spraying of forest nursery stock can help prevent the spread of DNB. However, the effectiveness of modern single‐site fungicides againstD. septosporumand the risk of fungicide resistance evolution remain largely unknown. In this project, we aimed to establish sensitivity profiles ofD. septosporumto some widely used single‐site fungicide classesin vitro, and to determine whether fungicide resistance is already present, as this could increase the spread ofD. septosporumgenotypes on planting stock in native woodlands. For this purpose, we compared isolates ofD. septosporum, originating from pine stands unexposed to fungicides, with isolates from nursery outbreaks, for sensitivity to a range of commonly applied fungicides. Most of the fungicides we tested were effectivein vitroand we observed no significant shifts in sensitivity in forest nurseries. Although further testsin plantaare required to confirm effectiveness of single‐site fungicides againstD. septosporum, our results suggest that they can be successfully used in DNB control, although appropriate measures to prevent the evolution of fungicide resistance are strongly recommended.
