THE GROWTH AND STATUS OF MYCORRHIZATION OF SEEDLINGS IN THE NATURAL REGENERATION OF SCOTS PINE CHEMICALLY TREATED AGAINST LOPHODERMIUM NEEDLE CAST

Keywords: ectomycorrhiza, fungicide, natural regeneration, Lophodermium needle cast, Scots pine
Abstract: The aim of the research was to evaluate the effect of two fungicides Falcon 460 EC and Gwarant 500 SC used to protect Scots pine against Lophodermium needle cast on the state of mycorrhizae and seedling growth. The subject of the research was natural regeneration of one-year-old pines in the Gostynin Forest Inspectorate. Falcon 460 EC was applied at a concentration of 0.15% and Gwarant 500 SC at a concentration of 0.5%, at a rate of 500 l/ha for both fungicides. The treatments were applied once or twice during the growing season. No occurrence of Lophodermium needle cast was detected either on treated or untreated pines. Only two mycorrhizal morphotypes were distinguished on pine seedling roots. The mycorrhization level of seedlings did not change after fungicide application. Both fungicides showed a limiting effect on the formation of complex structures: dychotomous and coralloid. None of the tested fungicides caused changes in seedling growth.
