Chestnut Trees

Chestnuts were ubiquitous plants and a valuable resource for the survival of populations in several geographic areas (e.g., Europe, Asia, parts of Africa)

It has been cultivated for its nuts and rot-resistant wood for thousands of years

The different species of chestnuts have been affected by insects and fungi that caused severe damages to the plants or their death. European chestnut has been affected by a cynipidae that lowered the production of nuts and wood.

American chestnut trees were decimated by a fungus that  caused the chestnut blight


Main Diseases


Chestnut Blight

Chestnut Tree affected by blight
Caused by the fungus Chryphonectria parasitica
Intorduced to North America in 1904, in Europe around..
Wilting leaves, large cankers with rupturing bark, death of the tree’s trunk and upper limbs
3.5 billion American chestnut trees lost due to blight from 1910-1950


Ink diseases


Chestnut tree affected by ink disease
Caused by Phytophthora cinnamomi and Pcambivora
Rot extended to the roots and the base of the trunk, defoliation, premature drying out of the foliage, unripe husks which cause gradual withering and death of the tree



Chestnut Gall Wasp Disease

Caused by Dryocosmus Kuriphilus

Brought from China to Japan and North America, then to north-western Italy in 2002. It has now spread throughout Italy and other European countries

Galls on growth buds and leaves, lower flowering, reduced growth, general weakening of the plants with increased disease secondary, lower production of chestnuts and timber
