In addition, experiments were conducted in planta to study the ability of phosphonic acid injections and metalaxyl-M drenches to control pathogen growth on saplings of California coast live oak (&lt;em&gt;Quercus agrifolia&lt;/em&gt;), and of copper hydroxide foliar sprays to control infection of California bay laurel (&lt;em&gt;Umbellularia californica&lt;/em&gt;) leaves. &lt;em&gt;Phytophthora ramorum&lt;/em&gt; was only moderately sensitive to phosphonic acid in vitro, but was highly sensitive to copper hydroxide. In planta experiments indicated the broad efficacy of phosphonic acid injections and of copper hydroxide sprays in preventing growth of &lt;em&gt;P. ramorum&lt;/em&gt; in oaks and bay laurels, respectively. Finally, although metalaxyl-M was effective in vitro, drenches of potted oak trees using this active ingredient were largely ineffective in reducing the growth rate of the pathogen in planta.&lt;/p&gt;</style></abstract></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Garbelotto, M.</style></author><author><style face="normal" font="default" size="100%">Davidson, J.</style></author><author><style face="normal" font="default" size="100%">K.

In addition to the affected oak species, we have now identified an additional 13 species from 10 plant families that act as hosts for &lt;em&gt;P. ramorum&lt;/em&gt; in California. Our data indicates that nearly all of the state’s main tree species in mixed-evergreen and redwood-tanoak forests — including the coniferous timber species coast redwood and Douglas fir — may be hosts for &lt;em&gt;P. ramorum&lt;/em&gt;. The broad host range of &lt;em&gt;P. ramorum&lt;/em&gt;, the variability of symptoms among different hosts and the ability of the pathogen to disperse by air suggests that it may have the potential to cause long-term, landscape-level changes in California forests.&lt;/p&gt;</style></abstract></record></records></xml>
