Because both pathogens have an overlapping geographic range in the UK and often concurrently invade the same site, it is speculated that &lt;em&gt;P. kernoviae&lt;/em&gt; may also invade North American (NA) forests threatened by &lt;em&gt;P. ramorum&lt;/em&gt;, the cause of Sudden Oak Death. This paper addresses the susceptibility of select NA plants to &lt;em&gt;P. kernoviae&lt;/em&gt;, including measures of disease incidence and severity on wounded and unwounded foliage. The potential for pathogen transmission and survival was investigated by assessing sporangia and oospore production in infected tissues. Detached leaves of &lt;em&gt;Rhododendron macrophyllum&lt;/em&gt;, &lt;em&gt;Rhododendron occidentale&lt;/em&gt; and &lt;em&gt;Umbellularia californica&lt;/em&gt;, and excised roots of &lt;em&gt;U. californica&lt;/em&gt; and &lt;em&gt;R. occidentale&lt;/em&gt; were inoculated with &lt;em&gt;P. kernoviae&lt;/em&gt; and percent lesion area was determined after 6 days. Leaves were then surface sterilized and misted to stimulate sporulation and after 24 h sporangia production was assessed. The incidence of symptomless infections and sporulation were recorded. All NA native plants tested were susceptible to &lt;em&gt;P. kernoviae&lt;/em&gt; and supported sporangia production; roots of &lt;em&gt;U. californica&lt;/em&gt; and &lt;em&gt;R. occidentale&lt;/em&gt; were both susceptible to &lt;em&gt;P. kernoviae&lt;/em&gt; and supported sporangia production. Oospore production was also observed in &lt;em&gt;U. californica&lt;/em&gt; roots. The results highlight the vulnerability of select NA native plants to infection by &lt;em&gt;P. kernoviae&lt;/em&gt;, suggest that symptomless infections may thwart pathogen detection, and underscore the importance of implementing a proactive and adaptive biosecurity plan.&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%">Fichtner, E.

The efficacy of clearance for long-term disease management is unknown, in part due to lack of knowledge of pathogen persistence in roots and emerging seedlings. The main objectives of this work were to (i) investigate whether both pathogens infect &lt;em&gt;R. ponticum&lt;/em&gt; roots, (ii) determine the potential for residual inoculum of &lt;em&gt;P. kernoviae&lt;/em&gt; to infect &lt;em&gt;R. ponticum&lt;/em&gt; seedlings in cleared woodlands, and (iii) assess potential for &lt;em&gt;R. ponticum&lt;/em&gt; roots to support survival and transmission of &lt;em&gt;P. kernoviae&lt;/em&gt;. Roots of &lt;em&gt;R. ponticum&lt;/em&gt; were collected from both unmanaged and cleared woodlands and assessed for pathogen recovery. Both &lt;em&gt;P. ramorum&lt;/em&gt; and &lt;em&gt;P. kernoviae&lt;/em&gt; were recovered from asymptomatic roots of &lt;em&gt;R. ponticum&lt;/em&gt; in unmanaged woodlands, and &lt;em&gt;P. kernoviae&lt;/em&gt; was recovered from asymptomatic roots from seedlings in cleared woodland. Oospore production of &lt;em&gt;P. kernoviae&lt;/em&gt; was observed in naturally infected &lt;em&gt;R. ponticum&lt;/em&gt; foliage and in inoculated roots. Roots also supported &lt;em&gt;P. kernoviae&lt;/em&gt; sporangia production. The results of this study suggest that post-clearance management of &lt;em&gt;R. ponticum&lt;/em&gt; regrowth is necessary for long-term inoculum management in invaded woodlands.&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%">Filip, G.

Affected trees may die rapidly but mortality is commonly preceded by several decades of severely restricted radial stem growth. Roots are often affected by one or more types of decay. Cypress mortality, locally termed ‘mal del cipres’, is similar to a major forest disease in North America: Port-Orford-cedar (&lt;em&gt;Chamaecyparis lawsoniana&lt;/em&gt;) root disease in Oregon and California and a major tree decline: Alaska yellow-cedar (&lt;em&gt;Chamaecyparis nootkatensis&lt;/em&gt;) decline in south-east Alaska.

Sixteen ‘medium&amp;nbsp;×&amp;nbsp;agar concentration&amp;nbsp;×&amp;nbsp;incubation temperature’ stress environments were tested to find a rapid and repeatable method to discriminate the known EU2 lineage from the EU1, NA1 and NA2 lineages in culture, in particular from the EU1 already prevalent across the UK; and to investigate whether EU2 might be adaptively different. At 28°C on both Carrot agar and V8 juice agar, the mean radial growth rates of all four lineages were significantly different, with NA2&amp;nbsp;&amp;gt;&amp;nbsp;EU2&amp;nbsp;&amp;gt;&amp;nbsp;EU1&amp;nbsp;&amp;gt;&amp;nbsp;NA1. At this temperature, EU2 colonies were not only phenotypically distinct from EU1 and all other lineages but on average grew three times as fast as EU1. This indicates that EU2 is adaptively different from EU1. Twelve days growth in the environment ‘V8A/2% agar/28°C gave excellent discrimination of all four lineages in three repeat experiments, including clear discrimination of EU2 from EU1. Each lineage exhibited a distinctive colony pattern. The utility of this test environment was examined further by screening fresh UK isolates of unknown lineage from new larch outbreak sites alongside standard isolates. The lineage assignments predicted were corroborated by gene sequencing and RFLP profiling. These results also revealed that the EU2 lineage was present at several new larch sites in south west Scotland, whereas isolates from geographically adjacent areas such as the Isle of Mull, north west Scotland, the Isle of Man and north west England were all of EU1 lineage.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">3</style></issue></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%">Susan J.

Restoration plantings may be conducted in high-value and limited habitats to sustain or re-establish rare plant populations. Once established, &lt;span class=&quot;html-italic&quot;&gt;Phytophthora&lt;/span&gt; pathogens infest the site and are very difficult to eradicate or manage—they degrade the natural resources the plantings were intended to enhance. To respond to unintended &lt;span class=&quot;html-italic&quot;&gt;Phytophthora&lt;/span&gt; introductions, vegetation ecologists took a variety of measures to prevent pathogen introduction and spread, including treating infested areas by solarization, suspending plantings, switching to direct seeding, applying stringent phytosanitation requirements on contracted nursery stock, and building their own nursery for clean plant production. These individual or collective actions, loosely coordinated by the Phytophthoras in Native Habitats Work Group ensued as demands intensified for protection from the inadvertent purchase of infected plants from commercial native plant nurseries. Regulation and management of the dozens of &lt;span class=&quot;html-italic&quot;&gt;Phytophthora&lt;/span&gt; species and scores of plant hosts present a challenge to the state, county, and federal agriculture officials and to the ornamental and restoration nursery industries. To rebuild confidence in the health of restoration nursery stock and prevent further &lt;span class=&quot;html-italic&quot;&gt;Phytophthora&lt;/span&gt; introductions, a voluntary, statewide accreditation pilot project is underway which, upon completion of validation, is planned for statewide implementation.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">12</style></issue></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%">Fraser, Stuart</style></author><author><style face="normal" font="default" size="100%">Gomez-Gallego, Mireia</style></author><author><style face="normal" font="default" size="100%">Gardner, Judy</style></author><author><style face="normal" font="default" size="100%">Bulman, Lindsay S.</style></author><author><style face="normal" font="default" size="100%">Denman, Sandra</style></author><author><style face="normal" font="default" size="100%">Williams, Nari M.</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Impact of weather variables and season on sporulation of Phytophthora pluvialis and Phytophthora kernoviae</style></title><secondary-title><style face="normal" font="default" size="100%">Forest Pathology</style></secondary-title><short-title><style face="normal" font="default" size="100%">For.

Little is known about the epidemiology of the diseases, making the development of control strategies challenging. To investigate the seasonality and climatic drivers of sporulation, inoculum traps, consisting of pine fascicles floating on water in plastic containers, were exchanged fortnightly at five sites in &lt;em&gt;P.&amp;nbsp;radiata&lt;/em&gt; plantations between February 2012 and December 2014. Sections of needle baits were plated onto selective media and growth of &lt;em&gt;Phytophthora&amp;nbsp;pluvialis&lt;/em&gt; and &lt;em&gt;P.&amp;nbsp;kernoviae&lt;/em&gt; recorded. To explore the generalizability of these data, they were compared to detection data for both pathogens from the New Zealand Forest Health Database (NZFHDB). Further, equivalent analyses on infection of &lt;em&gt;Rhododendron ponticum&lt;/em&gt; by &lt;em&gt;P.&amp;nbsp;kernoviae&lt;/em&gt; in Cornwall, UK allowed the comparison of the epidemiology of &lt;em&gt;P.&amp;nbsp;kernoviae&lt;/em&gt; across different host systems and environments. In New Zealand, inoculum of &lt;em&gt;P.&amp;nbsp;pluvialis&lt;/em&gt; and &lt;em&gt;P.&amp;nbsp;kernoviae&lt;/em&gt; was detected between January–December and March–November, respectively. Inoculum of both species peaked in abundance in late winter. The probability of detecting &lt;em&gt;P.&amp;nbsp;pluvialis&lt;/em&gt; and &lt;em&gt;P.&amp;nbsp;kernoviae&lt;/em&gt; was greater at lower temperatures, while the probability of detecting &lt;em&gt;P.&amp;nbsp;pluvialis&lt;/em&gt; also increased during periods of wet weather. Similar patterns were observed in NZFHDB data. However, the seasonal pattern of infection by &lt;em&gt;P.&amp;nbsp;kernoviae&lt;/em&gt; in the UK was the opposite of that seen for sporulation in New Zealand. &lt;em&gt;Phytophthora kernoviae&lt;/em&gt; was likely limited by warmer and drier summers in New Zealand, but by colder winter weather in the UK. These results emphasize the importance of considering both environmental drivers and thresholds in improving our understanding of pathogen epidemiology.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">2</style></issue></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%">Frezzi, MJ</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%"> Las especies de Phytophthora en la Argentina</style></title><secondary-title><style face="normal" font="default" size="100%"> Revista de Investigaciones Agricoles</style></secondary-title></titles><dates><year><style  face="normal" font="default" size="100%">1950</style></year></dates><volume><style face="normal" font="default" size="100%">4</style></volume><pages><style face="normal" font="default" size="100%">47-133</style></pages><language><style face="normal" font="default" size="100%">eng</style></language></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%">Funahashi, F.</style></author><author><style face="normal" font="default" size="100%">Parke, J.

We investigated the effects of soil solarization, alone or with subsequent amendment with a &lt;em&gt;Trichoderma asperellum&lt;/em&gt; biocontrol agent, on the survival of &lt;em&gt;Phytophthora&lt;/em&gt; spp. inoculum. In field trials conducted with &lt;em&gt;Phytophthora ramorum&lt;/em&gt; in San Rafael, CA and with &lt;em&gt;P. pini&lt;/em&gt; in Corvallis, OR, infested rhododendron leaf inoculum was buried at 5, 15, and 30 cm below the soil surface. Solarization for 2 or 4 weeks during summer 2012 eliminated recovery of &lt;em&gt;Phytophthora&lt;/em&gt; spp. buried at all depths in California trial 1, at 5 and 15 cm in California trial 2, but only at 5 cm in Oregon. There was no significant reduction of &lt;em&gt;Phytophthora&lt;/em&gt; spp. recovery after &lt;em&gt;T. asperellum&lt;/em&gt; application. Although the population densities of the introduced &lt;em&gt;T. asperellum&lt;/em&gt; at the 5-cm depth were often two- to fourfold higher in solarized compared with nonsolarized plots, they were not significantly different (&lt;em&gt;P&lt;/em&gt; = 0.052). Soil solarization appears to be a promising technique for disinfesting the upper layer of soil in container nurseries under certain conditions.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">2</style></issue></record></records></xml>
