Four fuel reduction treatments were applied to three sites in a southern Appalachian Mountain forest in western North Carolina: prescribed burning, mechanical fuel reduction, mechanical fuel reduction followed by prescribed burning, and a nontreated control. To determine the effects of fuel reduction treatments on &lt;em&gt;Phytophthora&lt;/em&gt; spp. in soil, incidences were assessed once before and twice after fuel reduction treatments were applied. Also, the efficiency of the baiting bioassay used to detect species of &lt;em&gt;Phytophthora&lt;/em&gt; was evaluated, and the potential virulence of isolates of &lt;em&gt;Phytophthora&lt;/em&gt; spp. collected from forest soils was determined. &lt;em&gt;Phytophthora cinnamomi&lt;/em&gt; and &lt;em&gt;P. heveae&lt;/em&gt; were the only two species recovered from the study site. Incidences of these species were not significantly affected by fuel reduction treatments, but incidence of &lt;em&gt;P. cinnamomi&lt;/em&gt; increased over time. In the baiting bioassay, camellia leaf disks were better than hemlock needles as baits. &lt;em&gt;P. cinnamomi&lt;/em&gt; was detected best in fresh soil, whereas &lt;em&gt;P. heveae&lt;/em&gt; was detected best when soil was air-dried and remoistened prior to baiting. Isolates of &lt;em&gt;P. heveae&lt;/em&gt; were weakly virulent and, therefore, potentially pathogenic—causing lesions only on wounded mountain laurel and rhododendron leaves; however, isolates of &lt;em&gt;P. cinnamomi&lt;/em&gt; were virulent and caused root rot and mortality on mountain laurel and white pine plants.&lt;/p&gt;</style></abstract></record></records></xml>
