We're losing chestnut trees in Turkey fast as well. Causes: - Phytophthora cambivora (ink disease) - also by: P. cinnamomi, P. plurivora and P. cryptogea - Cryphonectria parasitica (chestnut blight) - gall wasp (Dryocosmus kuriphilus) In Kastamonu and Sinop, modest success reported against blight in treated areas but I don't think the spread is easy to contain. Need to note, blight suspected to have set foot in Turkey in 70s, started to become significant in 90s and now we're losing most. Chestnut has suddenly become hard to reach this year by additional effect of Gall wasp.
