Abstract
Pitomi kesten (Castanea sativa) je listopadna drvenasta vrsta koja potječe iz Male Azije, a u Europi je
rasprostranjena najviše u južnom dijelu te Sredozemlju. Ova vrsta je značajna u šumskim ekosustavima, ali se i
uzgaja zbog jestivog ploda te kao ukrasno drvo. Najčešći uzročnici bolesti pitomog kestena su fitopatogena gljiva
Cryphonectria parasitica koja uzrokuje rak kore pitomog kestena, vrste iz roda Phytophtora koje uzrokuju tintnu
bolest te osa šiškarica (Dryocosmus kuriphilus). Najčešći simptomi bolesti su nekroze, sušenje i odumiranje
dijelova ili cijele biljke. Kao zaštita koriste se najčešće mehaničke metode, a za rak kore pitomog kestena vrlo je
značajna biološka kontrola bolesti pomoću virusa Cryphonectria hypovirus 1.European chestnut (Castanea sativa) is a deciduous tree species originating from Asia Minor, and
in Europe it is most common in the southern part and in the Mediterranean area. This species is significant in
forest ecosystems, but it is also cultivated for edible fruit and as an ornamental tree. The most common pathogens
of European chestnut are phytopathogenic fungus Cryphonectria parasitica which causes chestnut blight, species
of the genus Phytophtora which cause ink disease and gall wasp (Dryocosmus kuriphilus). The most common
symptoms of the diseases are necrosis, drying and dying of parts or whole plants. For the purpose of prevention
mechanical methods are most commonly used, while biological control using virus Cryphonectria hypovirus 1 is
significant for chestnut blight disease
