Investigations were conducted in the years 2007–2008 at the Department of Phytopathology, Poznań University of Life Sciences. The study presents the evaluation of efficacy of three selected preparations: Biochikol 020 PC (chitosan), Mirage 450 EC (prochloraz) and Topsin M 500 SC (thiophanate-methyl) recommended for protection of coniferous ornamental plants against fungal pathogens. In the experiments isolates of the following fungi were used: Fusarium oxysporum, F. avenaceum, F. tricinctum, Cylindrocarpon magnusianum and Rhizoctonia solani collected from infested plants, pathogenicity of which was confirmed in earlier infection experiments. Laboratory analyses were conducted to investigate the effect of preparations on linear increase in mycelial growth of the examined isolates. The inhibitory action was found for all tested preparations. In the greenhouse experiment the plant material included Chamaecyparis lawsoniana, Juniperus chinensis, Pseudotsuga menziesii and Thuja occidentalis. Inoculum of the tested fungi was introduced to pots with growing plants. Plants were sprayed twice with the tested preparations at 2-week intervals. Observations of plants were performed in the course of the experiment. It was found that both in laboratory analyses and greenhouse experiments the preparation Topsin M 500 SC proved to be the least effective. Mirage 450 EC and Biochikol 020 PC were significantly more effective and did not differ statistically.
