A recent well-known example is &lt;em&gt;Phytophthora ramorum&lt;/em&gt;, the causal agent of sudden oak death, which emerged in the 1990s in Europe and North America. In Europe, this pathogen is mainly restricted to woody ornamentals in nurseries and public greens, while severe outbreaks in the wild have only been reported in the UK. This study presents the results of the &lt;em&gt;P.&amp;nbsp;ramorum&lt;/em&gt; survey conducted in Swiss nurseries between 2003 and 2011. In all 120 nurseries subjected to the plant passport system, the main &lt;em&gt;P.&amp;nbsp;ramorum&lt;/em&gt; hosts were visually checked for above ground infections. &lt;em&gt;Phytophthora&lt;/em&gt; species were isolated from tissue showing symptoms and identified on the basis of the morphological features of the cultures and sequencing of the ribosomal ITS region. &lt;em&gt;Phytophthora&lt;/em&gt; was detected on 125 plants (66 &lt;em&gt;Viburnum&lt;/em&gt;, 58 &lt;em&gt;Rhododendron&lt;/em&gt; and one &lt;em&gt;Pieris&lt;/em&gt;). &lt;em&gt;Phytophthora ramorum&lt;/em&gt; was the most frequent species (59·2% of the plants), followed by &lt;em&gt;P.&amp;nbsp;plurivora&lt;/em&gt;,&lt;em&gt; P.&amp;nbsp;cactorum&lt;/em&gt;,&lt;em&gt; P.&amp;nbsp;citrophthora&lt;/em&gt;,&lt;em&gt; P.&amp;nbsp;cinnamomi&lt;/em&gt;,&lt;em&gt; P.&amp;nbsp;cactorum/P.&amp;nbsp;hedraiandra&lt;/em&gt;,&lt;em&gt; P.&amp;nbsp;multivora&lt;/em&gt; and &lt;em&gt;P&lt;/em&gt;.&amp;nbsp;taxon PgChlamydo. The highest incidence of &lt;em&gt;P.&amp;nbsp;ramorum&lt;/em&gt; was observed on &lt;em&gt;Viburnum&amp;nbsp;&lt;/em&gt;×&amp;nbsp;&lt;em&gt;bodnantense&lt;/em&gt;. Microsatellite genotyping showed that the Swiss &lt;em&gt;P.&amp;nbsp;ramorum&lt;/em&gt; population is highly clonal and consists of seven genotypes (five previously reported in Europe, two new), all belonging to the European EU1 clonal lineage. It can therefore be assumed that &lt;em&gt;P.&amp;nbsp;ramorum&lt;/em&gt; entered Switzerland through nursery trade. Despite sanitation measures, repeated &lt;em&gt;P.&amp;nbsp;ramorum&lt;/em&gt; infections have been recorded in seven nurseries, suggesting either reintroduction or unsuccessful eradication efforts.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">5</style></issue></record></records></xml>
