Abstract: Sweet chestnut (Castanea sativa Mill.) is one of the most endangered tree species. Its survival in our country does not depend on the climate as much as on the sensitivity to fungus Cryphonectria parasitica (Murrill) Barr which causes “chestnut blight”. Besides this fungus, grave damages to Sweet chestnut are also caused by species from Phytophthora genus causing “chestnut ink disease”. This paper states the fungi which appear most frequently on chestnut in two localities in the vicinity of Vranje. The total of 13 fungal species was reported. The most significant of them is Cryphonectria parasitica, which is present in both localities. In both localities the Izs is extremely high (2.93 and 2.5), which points to the fact that the tree damage is great. The most significant species reported on leaves is Mycosphaerella maculiformis, and on the fruits Stromatinia pseudotuberosa is of the highest significance.

Opis (srp)

Izvod: Pitomi kesten (Castanea sativa Mill.) spada u najugroženije vrste drveća. Njegov opstanak kod nas ne zavisi toloko ni od klime koliko od osetljivosti prema gljivi Cryphonectria parasitica (Murrill.) Barr. koja izaziva “rak kore kestena”. Pored ove gljive velike štete na pitomom kestenu izazivaju i vrste iz roda Phytophthora koje izazivaju “mastiljavu bolest” kestena. U radu su navedene gljive koje se najčešće javljaju na kestenu na dva lokalitete u okolini Vranja. Ukupno je zabeleženo prisustvo 13 vrsta gljiva. Najveći značaj ima vrsta Cryphonectria parasitica, koja je prisutna na oba lokaliteta. IZS na oba lokaliteta je veoma visok (2,93 i 2,5) što ukazuje da je stepen oštećenja stabala veliki. Najznačajnija vrsta konstatovana na lišću je Mycosphaerella maculiformis, a na plodovima najveći značaj ima Stromatinia pseudotuberosa.
