The disease symptoms consist basically of a decay of the trees canopy that may occur as a slow decline: gradualleaves fall and presence of partially or totally defoliated branches, or as a quick decline: rapid decline of branches, leaves remaining attached sorne time, and dead trees. There may also be blackish gummose exudates on trunk and main branches. The &quot;seca&quot; reached epidemic rates in the various evergreen oaks or cork oaks distributed on Andalusia, Castilla-La Mancha and Extremadura since 1990-91. From then in the soils of these forestry areas and on feeder roots of cork oaks and evergreen oaks, P. cinnamomi were isolated along the climatological seasons until now. The continued presence of the fungi has lead to determine the susceptibility of Q. ilex subsp. hallota on adult trees in the field. Adult evergreen oak plants were inoculated with young mycelium of P. cinnamomi at La Iglesuela (Toledo) in spring, 1994. At two years, the development of this fungus on roots, trunks and branches of evergreen oak:, shows a great pathogenic capacity and it has achieved the reproduction of clear symptoms of &quot;seca&quot;</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%">LUQUE, J</style></author><author><style face="normal" font="default" size="100%">Girbal, J</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Dieback of cork oak (Quercus suber) in Catalonia (NE Spain) caused by Botryosphaeria stevensii</style></title><secondary-title><style face="normal" font="default" size="100%">European Journal of Forest Pathology</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">Botryosphaeria stevensii</style></keyword><keyword><style  face="normal" font="default" size="100%">canker</style></keyword><keyword><style  face="normal" font="default" size="100%">Cork oak</style></keyword><keyword><style  face="normal" font="default" size="100%">dieback</style></keyword><keyword><style  face="normal" font="default" size="100%">diplodia mutila</style></keyword><keyword><style  face="normal" font="default" size="100%">morphology (PG)</style></keyword><keyword><style  face="normal" font="default" size="100%">Symptoms</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">1989</style></year></dates><publisher><style face="normal" font="default" size="100%">Blackwell Publishing Ltd</style></publisher><volume><style face="normal" font="default" size="100%">19</style></volume><pages><style face="normal" font="default" size="100%">7-13</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">Botryosphaeria stevensii Shoemaker (anamorph: Diplodia mutila Fr. apud Mont.) is reported as the cause of canker and dieback of cork oak (Quercus suber L.) in Catalonia (NE Spain).

The dry canker is a complex syndrome consisting of wilting and trunk canker lessions. The disease occurs in an acute form and then the tree dies quickly after cork removal; or it can follow an insidious form and the tree can react and form several layers of cork before dying. A description of the simptomatology is given. The fungus Diplodia sp. is isolated from diseased trees and it has infectious capatity on the living tissues. The isolate has conidial characteristics that slightly differ from other Diplodia parasitic in Quercus. Because the taxonomic revision of the genus is lacking we have not given an species name. The relation between ecological stress and disease is emphasized and some possible preventive measures are given.</style></abstract></record></records></xml>
