Abstract
This study was conducted in Abies cilicica stands in Seydişehir Forestry Enterprise of Konya Regional Directorate of Forestry. The aim of the study was to determine the efficacy of selected biological and chemical control agents against establishment of the root and butt rot pathogen Heterobasidion abietinum. In field trials, spore solutions of Trichoderma harzianum and Phlebiopsis gigantea isolates, 30% aqueous urea solution and borax powder were applied onto the freshly cut A. cilicica stumps. Within one hour after the treatments the stumps were inoculated with the pathogen. In order to evaluate the growth of the fungus inside the trunk, living trees were cut into six 1-m-long sections starting from 0.5 m height. Approximately 2-cm-thick discs were then taken from the bottom of each section. A total of 120 disks, collected from the study areas, were investigated for the presence of the conidiophores of H. abietinum in the laboratory. The mean efficacies of urea, T. harzianum, borax and P. gigantea were 98.8, 96.4, 96.3, and 72.3%, respectively. The decay inside the trunk caused by the pathogen reached up to 5.5 meters.
