For. Abstr. 11 (Nos. 1468, 2268)]. The author concludes that &lt;em&gt;Phytophthora cinnamomi&lt;/em&gt; plays a great part in disease of Chestnut in Spain, Portugal, France and Italy, and elsewhere in southern Europe, and is probably the major cause of death in the more southerly regions. &lt;em&gt;P. cinnamomi&lt;/em&gt; has a considerable range of hosts. It has been found to attack &lt;em&gt;Castanea sativa, Juglans regia, Pseudotsuga taxifolia, Quercus robur, Q. suber, Betula alba, Cedrus atlantica, Abies nordmanniana, A. alba, A. sibirica&lt;/em&gt; and &lt;em&gt;Castanea crenata&lt;/em&gt; var. &lt;em&gt;tamba&lt;/em&gt;. A close watch on Douglas Fir in the U.S.A. seems advisable in case a strain of the fungus should encounter and attack it. In contrast &lt;em&gt;P. cambivora&lt;/em&gt; has only been found on &lt;em&gt;Castanea sativa&lt;/em&gt; and &lt;em&gt;C. crenata&lt;/em&gt; var. &lt;em&gt;tamba&lt;/em&gt;.&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%">Crandall, B.S.</style></author><author><style face="normal" font="default" size="100%">G.F.

The author gives an outline of the work leading to the identification of the fungus, and reports on inoculation and field tests that have proved its pathogenicity on Chestnut and other hosts. The fungus causes a similar root disease in forest-tree nursery stock. Infection has been observed in the nursery on twenty broadleaf and coniferous species. Field and greenhouse inoculation tests have demonstrated the susceptibility to the disease of European Chestnut (&lt;em&gt;Castanea sativa&lt;/em&gt;). The Asiatic species, &lt;em&gt;C. crenata&lt;/em&gt;, &lt;em&gt;C. mollissima&lt;/em&gt;, &lt;em&gt;C. henryi&lt;/em&gt;, and &lt;em&gt;C. seguinii&lt;/em&gt;, however, show a high degree of resistance. It seems probable that root rot of this type has been responsible for the recession of the American Chestnut in some areas of the United States. No satisfactory control measures have been evolved. Hybrid varieties resistant to both blight and root rot are being developed by crossing American Chestnut and Chinkapins with Asiatic species.&lt;/p&gt;</style></abstract></record></records></xml>
