Two European and two USA isolates were used. Wounded and unwounded leaves were dipped in zoospore suspensions during summer; conifers were also tested in winter. Successful infection of tissue and amount of necrosis were assessed. Highly susceptible broad-leaved hosts included &lt;em&gt;Aesculus hippocastanum&lt;/em&gt;, &lt;em&gt;Fraxinus excelsior&lt;/em&gt;, &lt;em&gt;Quercus ilex&lt;/em&gt;, &lt;em&gt;Ulmus procera&lt;/em&gt; and, to a lesser extent, &lt;em&gt;Castanea sativa&lt;/em&gt;, &lt;em&gt;Q. cerris&lt;/em&gt; and &lt;em&gt;Q. petraea&lt;/em&gt;, together with &lt;em&gt;Umbellularia californica&lt;/em&gt; and rhododendrons. &lt;em&gt;Acer pseudoplatanus&lt;/em&gt;, &lt;em&gt;Alnus glutinosa&lt;/em&gt;, &lt;em&gt;Carpinus betulus&lt;/em&gt;, &lt;em&gt;Corylus avellana&lt;/em&gt;, &lt;em&gt;Fagus sylvatica&lt;/em&gt;, &lt;em&gt;Prunus avium&lt;/em&gt;, &lt;em&gt;Q. robur&lt;/em&gt;, &lt;em&gt;Q. rubra&lt;/em&gt; and &lt;em&gt;Q. suber&lt;/em&gt; showed consistently low susceptibility. Conifer species including &lt;em&gt;Abies procera&lt;/em&gt;, &lt;em&gt;Picea abies&lt;/em&gt;, &lt;em&gt;P. sitchensis&lt;/em&gt;, &lt;em&gt;Pseudotsuga menziesii&lt;/em&gt;, &lt;em&gt;Sequoia sempervirens&lt;/em&gt; and &lt;em&gt;Tsuga heterophylla&lt;/em&gt; were also susceptible. &lt;em&gt;Pseudotsuga menziesii&lt;/em&gt; and &lt;em&gt;A. procera&lt;/em&gt; were severely affected. &lt;em&gt;Pinus contorta&lt;/em&gt;, &lt;em&gt;P. nigra&lt;/em&gt; var. &lt;em&gt;maritima&lt;/em&gt; and &lt;em&gt;P. sylvestris&lt;/em&gt; were virtually resistant, while &lt;em&gt;Taxus baccata&lt;/em&gt; was only slightly affected. Increased necrosis was apparent on leaves that were wounded prior to inoculation. These results extend the known range of trees that &lt;em&gt;P. ramorum&lt;/em&gt; is able to attack and confirm its relative host-nonspecificity.&lt;/p&gt;</style></abstract></record></records></xml>
