Chalara fraxinea

Alain GARDIENNET, 23-05-2011 00:02

Bonsoir,
Nous observons dans le Nord-Est de la France une attaque de ce champignon sur les frênes (il viendrait de Pologne, merci Piotr ! ;) ).
Quelqu'un aurait-il la publication suivante :
Ref #: 32538
Author(s): Kowalski, T.
Title: Chalara fraxinea sp. nov. associated with dieback of ash (Fraxinus excelsior) in Poland
Journal: Forest Pathology
Volume: 36
Issue: 4
Page(s): 264-270
Year: 2006
Quelqu'un saurait-il aussi quoi faire contre ce redoutable fraxinicide ?
Alain
