Various attacks of pathogenic fungi on the larch crown were observed in Trentino/South Tyrol, Italy, over the past few years.

Abstract
Various attacks of pathogenic fungi on the larch crown were observed in Trentino/South Tyrol, Italy, over the past few years. In 1999, severe defoliation was caused by Mycosphaerella laricina, a rarely investigated pathogen, whose action was enhanced by high temperatures and humidity in August. In July 2000, larch woods showed crown yellowing due to Meria lands. Lower temperatures and heavy precipitation were probably the predisposing factors in this case. Hypodermella laricis was observed in 2002 as a localised attack, while Lachnellula wilkommii is commonly recorded. The impact of these diseases and the environmental factors involved in their occurrence are discussed in this paper.I documenti in FLORE sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
