It has been proposed that dead &lt;em&gt;Banksia grandis&lt;/em&gt; are a significant long-term reservoir for &lt;em&gt;P.&amp;nbsp;cinnamomi&lt;/em&gt; inoculum. To test this, 36 healthy &lt;em&gt;B.&amp;nbsp;grandis&lt;/em&gt; trees were inoculated in April 1999, and the presence of viable propagules &lt;em&gt;in planta&lt;/em&gt; was determined between 2 and 34&amp;nbsp;months after tree death. By 10&amp;nbsp;months after inoculation, 75% of the trees had died, with the remaining seven trees dying by 22&amp;nbsp;months. The pathogen was more commonly recovered from bark than from wood, except from those trees that died at 22&amp;nbsp;months, and more commonly from above-ground trunks than below-ground trunks and roots until 8&amp;nbsp;months after plant death. In trees that died 12&amp;nbsp;months after inoculation, &lt;em&gt;P.&amp;nbsp;cinnamomi&lt;/em&gt; was recovered from 60% of trunk and root core samples at 3&amp;nbsp;months, declining to 33% at 10&amp;nbsp;months, 5.5% at 12&amp;nbsp;months and 0.1% at 34&amp;nbsp;months after tree death. In trees that died at 22&amp;nbsp;months, &lt;em&gt;P.&amp;nbsp;cinnamomi&lt;/em&gt; was recovered from 87% of trunk and root samples 2&amp;nbsp;months after tree death, decreasing to 0.5% by 33&amp;nbsp;months. This study suggests that the pathogen does not have a saprotrophic phase within dead &lt;em&gt;B.&amp;nbsp;grandis&lt;/em&gt; tissue, and &lt;em&gt;B.&amp;nbsp;grandis&lt;/em&gt; is unlikely to be a long-term reservoir for &lt;em&gt;P.&amp;nbsp;cinnamomi&lt;/em&gt;. However, the manipulation of the density of &lt;em&gt;B.&amp;nbsp;grandis&lt;/em&gt; and the use of fire to facilitate the breakdown of dead &lt;em&gt;Banksia&lt;/em&gt; trunks in the &lt;em&gt;Eucalyptus marginata&lt;/em&gt; (jarrah) forest may reduce the spread and impact of &lt;em&gt;P.&amp;nbsp;cinnamomi&lt;/em&gt;.&lt;/p&gt;</style></abstract></record></records></xml>
