Isolates recovered from these hosts and isolates of 6 &lt;em&gt;Phytophthora&lt;/em&gt; species previously recovered from Douglas-fir &lt;em&gt;(Pseudotsuga menziesii)&lt;/em&gt; were then tested for pathogenicity on seedlings of 9 Northwest conifers. &lt;em&gt;P. megasperma&lt;/em&gt; Group 1, &lt;em&gt;P. cryptogea&lt;/em&gt;, and &lt;em&gt;P. cinnamomi&lt;/em&gt; were pathogenic to all tree species except western redcedar &lt;em&gt;(Thujaplicata).&lt;/em&gt; Western hemlock &lt;em&gt;(Tsuga heterophylla)&lt;/em&gt; and true firs were susceptible to most species tested; ponderosa &lt;em&gt;(P. ponderosa)&lt;/em&gt; and sugar pines were damaged only by &lt;em&gt;P. cryptogea&lt;/em&gt; and &lt;em&gt;P. cinnamomi;&lt;/em&gt; western redcedar was resistant to all isolates.&lt;/p&gt;</style></abstract></record></records></xml>
