[IUFRO RG 7.02 FORPATH] Phomopsis in spruce

Hello colleagues, Our plant disease clinic here in Columbus, Ohio, has been observing higher incidence of Phomopsis spp. associated with tip dieback in spruce (both Norway and Colorado blue spruce) in the last few years, whereas the usual culprit used to be cytospora in the past. Has anyone else observed the same? We are just wondering if this is something worth following up. Thanks! Enrico -- ----------------------------------------- Pierluigi (Enrico) Bonello, Assoc.
