\"GFPF_photo\"<\/a>The GFPF seminar (Groupe Francophone de Pathologie Foresti\u00e8re)\u00a0was held recently for three days in Hendaye from 14-16 October 2014<\/strong><\/strong><\/p>\n

\n

Jointly organized by the D\u00e9partement de la Sant\u00e9 des For\u00eats (DSF-MAAF) and the UMR IAM and partially funded by grants from Labex ARBRE, the seminar gathered 38 participants, mostly from DSF, INRA Bordeaux and INRA Nancy-Lorraine, including 10 scientists or technicians from the UMR IAM. Fourteen presentations were given, including six by IAM team members, about recent results on the epidemiology of the major pathosystems currently being studied: Poplar rust, Alder Phytophthora and Ash Dieback.<\/p>\n

The seminar\u2019s major focus was on the introduction of emerging diseases, such as Ash dieback, ink diseases (on oaks and chestnuts) due to\u00a0Phytophthora<\/em>\u00a0cinnamomi<\/em>\u00a0and Pitch Canker, a new disease on Pines caused by\u00a0Gibberella<\/em>\u00a0circinata<\/em>. This fungus is common in North America where it causes canker and necrosis on twigs, branches, trunks and roots of many pine species. It was introduced in Europe in the 1990s and is now well established in northern Spain. Aside from a few cases\u00a0 that appeared in the early 2000s, the disease has not yet spread to France. The GFPF meeting also included field tours of forests in Spain to visit infected areas to better understand the disease symptoms and the host range. Discussions also addressed the risk of Pitch Canker spreading to France, particularly to southwestern France where the climate would favor establishment of this disease and where the presence of susceptible species is particularly dense.<\/p>\n

Le s\u00e9minaire bisannuel du GFPF (Groupe Francophone de Pathologie Foresti\u00e8re) s\u2019est d\u00e9roul\u00e9 \u00e0 Hendaye du 13 au 16 octobre 2014<\/strong><\/p>\n

Organis\u00e9 conjointement par le D\u00e9partement de la Sant\u00e9 des For\u00eats (DSF-MAAF) et l\u2019UMR IAM avec un cofinancement du Labex ARBRE, ce s\u00e9minaire a rassembl\u00e9 trente-huit participants, provenant essentiellement du DSF, de l\u2019INRA Bordeaux et de l\u2019INRA Nancy-Lorraine, dont 10 agents (permanents ou non) de l\u2019UMR IAM. Les sessions en salle (1 journ\u00e9e) ont permis \u00e0 l\u2019UMR IAM de diffuser leurs derniers r\u00e9sultats sur l\u2019\u00e9pid\u00e9miologie des principaux pathosyst\u00e8mes abord\u00e9s dans l\u2019Unit\u00e9\u00a0(6 pr\u00e9sentations orales) : la rouille du Peuplier, le Phytophthora de l\u2019Aulne et la chalarose du Fr\u00eane.<\/p>\n

Cette ann\u00e9e, le s\u00e9minaire \u00e9tait principalement ax\u00e9 sur les maladies \u00e9mergentes d\u2019origine exotique, comme la chalarose, l\u2019encre du ch\u00eane et du ch\u00e2taignier due \u00e0\u00a0Phytophthora cinnamomi<\/em>\u00a0et surtout le Pitch Canker, une maladie sur Pin caus\u00e9e par\u00a0Gibberella circinata<\/em>. Ce champignon commun en Am\u00e9rique du Nord et qui provoque des d\u00e9g\u00e2ts sur rameaux, branches, troncs et racines sur de nombreuses esp\u00e8ces de Pin et sur Douglas a \u00e9t\u00e9 introduit en Europe \u00e0 la fin des ann\u00e9es 1990. Il est aujourd\u2019hui bien implant\u00e9 en Espagne et notamment dans le pays basque espagnol. En France, malgr\u00e9 quelques rares mentions au d\u00e9but des ann\u00e9es 2000, la maladie ne s\u2019est jusqu\u2019\u00e0 pr\u00e9sent pas d\u00e9velopp\u00e9e. Des visites de terrain en Espagne ont permis aux participants de se familiariser avec les sympt\u00f4mes de la maladie et de d\u00e9battre sur le risque Pitch Canker en France, notamment dans le sud-ouest o\u00f9 le climat semble favorable et o\u00f9 la densit\u00e9 de plantations d\u2019esp\u00e8ces sensibles est tr\u00e8s \u00e9lev\u00e9e.<\/p>\n
