Pathogenic micromycete species functioning in the rhizosphere of sick pot-plants growing in peat substrate
Agronomy Research 4 (special issue), 393-396
Abstract: During 1994-2005 investigations were carried out on 53 taxa of ornamental pot-plants belonging to 26 cultivars, 48 species, 35 genera, and 15 families. From the rhizosphere of 43% plants kept under unfavourable growth conditions plant pathogens were isolated from the following genera: Fusarium (8 species), Pythium (6 species), Verticillium (5) and Sclerotinia sclerotiorum, Thielaviopsis basicola, Rhizoctonia solani. Simultaneously on each sick plant rhizosphere there functioned several species of pathogenic micromycetes: from Aechmea fasciata - Fusarium equiseti, F. oxysporum and Pythium irregulare; from Dieffenbachia seguine - Fusarium oxysporum, Pythium aristosporum, P. debaryanum, from Dracaena fragrans - Fusarium oxysporum and Pythium.irregulare; from Dracaena marginata - Fusarium oxysporum and Pythium flavoense; from Alocasia x amazonica - Fusarium oxysporum and Verticillium nubilum.
