Intensity of fungal diseases of small-leaved lime (Tilia cordata mill.) across urban greeneries of Lithuania

Abstract

A small-leaved lime (Tilia cordata Mill.) is the dominant tree species in urban plantings throughout Lithuania. Therefore, it is important to assess the health of lime trees and to identify their most common fungal diseases. The average disturbance score for the mostly prevalent diseases was estimated. Apiognomonia errabunda, Armillaria mellea, Asteroma tiliae, Chondrostereum purpureum, Cytospora leucosperma, Diaporthe eres, Flammulina velutipes, Leptoxyphium fumago, Mycosphaerella millegrana, Nectria cinnabarina, Pholiota aurivella, Polyporus squammosus, Schizophyllum commune, Septoria tiliae and Tyrostroma compactum were the most common and important pathogens affecting streets and recreational lime plantings in Vilnius city in 2005–2011. Disease intensity fluctuated during the investigation period due to climatic conditions. The trees that grew under unfavourable climate in the streets plantings were less healthy than those grown under favourable climate in city recreational plantings
