Abstract

In Austrian pine plantations in Serbia, the greatest damage is caused by the fungi Mycosphaerella pini, Sphaeropsis sapinea, Cenangium ferruginosum, Germmeniella abietina (in the mountain regions) and occasionally Armillaria spp., Lophodermium spp. (seditiosum, conigenum, pinastri) and Cyclaneusma niveum. In Scots pine plantations, the greatest damage is caused by the fungi Heterobasidion annosum (especially in plantations on sandy soils), Armillaria spp, Lophodermium seditiosum, L. pinastri, Cyclaneusma minus and Sphaeropsis sapinea. Damage caused by rust fungi (Coleosporium sennecionis, Melampsora pinitorqua and Cronartium flaccidum) occurs less frequently. In mountainous regions in Scots pine plantations, great damage is caused by Phacidium infestans, Lophodermella sulcigena and Gremmeniella abietina.

Summary

Introduction

Intensive afforestation of bare lands and deforested areas in the area of the former Yugoslavia was undertaken in the second half of the XX century. The most frequent species in afforestation were Pinus species, and in Serbia especially Austrian pine and Scots pine plantations were established on large areas. During detailed health investigation of Scots pine and Austrian pine plantations, some dangerous pathogenic fungi were identified which had not been previously recorded in the area of Serbia. Some of them, such as Gremmeniella abietina, Phacidium infestans and Lophodermella sulcigena, were on the list of quarantine diseases. Some of these parasitic fungi had probably been present previously in our forests, but the symptoms of their diseases were often confused with the symptoms of some common diseases. For example, the symptoms of the disease caused by the fungus G. abietina can be confused with the symptoms of the disease caused by the fungus Cenangium ferruginosum, and the symptoms of Lophodermella sul­ cigena can be confused with the symptoms of the disease caused by the fungi in the Lo­ phodermium genus
