Diseases

Blight is the disease attacking the chestnut tree with which the public

is most familiar. The Chinese chestnut is strongly resistant although

not immune as few old trees entirely escape attack in areas where blight

is prevalent. In most cases healthy vigorous trees of this species

overcome the disease within a few years after being attacked. The ones

that die are usually those that have been devitalized in some way. The

nuts are subject to attack by any of several diseases either before or

after the harvest. A preliminary report on these has been made by

Gravatt and Fowler.[5]
