Scots pine is the most common tree species in Poland with the share in the species structure of Polish forests exceeding 58%. The most dangerous pathogen of this species is Phellinus pini (Brot.) Pilát), which causes the white pocket rot (also called red ring rot) of pine heartwood. It is estimated that as a result of the fungus’s activity, about 8% of annually harvested pine stems is damaged and...
The dynamic recent development of technologies provides more and more new tools, thanks to which it is possible to quickly detect and identify the chemical composition of volatile organic compounds of fungal origin. An ‘electronic nose’ (e−nose) is one of such tools. The Forest Research Institute launched in the period of 2018−2020 the project entitled ‘Forecasting threats to forest ecosystems through...
The Białowieża Forest (BF) is in many respects an exceptional object, of a great importance for nature protection and forest management, at the international scale. The BF plays also a key role from the point of view of regional development and welfare of local community. In the last period, a big threat for multiple values of the BF has arisen, as a result of enormous bark beetle infestation, which...
The aim of the study was to evaluate in mycological aspect stored horseradish seedlings derived from the strict field experiment, with an application of chemical and non-chemical protection. Regardless of protection manner, the population of fungi present in horseradish seedlings was dominated by the following species: V. dahliae (14%), C. destructans (8%), E. purpurascens (7.7%), R. solani (7.3%),...
The study aimed at the evaluation of the efficacy of horseradish seedling treatment with chitosan (Biochikol 020 PC) for the protection of the roots against Verticillium wilt and influence on the size and root yield structure. The direct effect of chitosan on the fungi which contribute to the degradation of root health was tested in laboratory conditions. The horseradish root yield and contribution...
The subject of the study concerns the seeds of broad bean of White Hangdown cultivar derived from the strict field experiment (2010-2012). The experiment consisted of 10 combinations including two alternating rows sowings of broad bean with fennel and coriander, four variants of biological protection using Polyversum WP, Bioczos BR, Biosept 33 SL preparations, and three variants of chemical protection...
The aim of the study was to search for alternatives to chemical fungicides currently used in plants protection against Botrytis cinerea, Rhizoctonia solani, Phoma exiqua var. exiqua, Sclerotinia sclerotiorum, Fusarium poae. Various concentrations of aqueous extracts of Chenopodium quinoa Willd leaves, stems and inflorescences were tested in the laboratory conditions. Antifungal activity of the extracts...
Ochrona upraw przed grzybami patogenicznymi dla roślin jest jednym z podstawowych elementów zapewniających wysokie plony. Niestety, odporność na fungicydy jest zjawiskiem coraz częściej występującym u patogenów. Przyczyną zaniku ochronnego działania stosowanych substancji czynnych są najczęściej mutacje w genach białek targetowych dla fungicydów. Do innych czynników powodujących wzrost odporności...
Mountain pine (Pinus mugo) is the most important component of the sub−alpine and alpine zone in the Tatras, and other ranges of central Europe. In Poland, only population from the Karko− nosze Mts. has been studied in terms of phytopathological threats so far. There is not much information on the diseases caused by fungi in the mountain pine from other regions either. The mycological analyses of infected...
Investigations concerned the horseradish roots originating from a strict field experiment conducted in 2010-2011, in which chemical protection using: Topsin M 500, Dithane 455 SC, Penncozeb 80WP and Amistar 250 SC and non-chemical protection by Polyversum WP biopreparation and biotechnological preparations: Biosept 33SL, Bioczos BR and Biochikol 020 PC were applied. Irrespectively of the applied protection,...
W badaniach skuteczności działania preparatów chemicznych zastosowano Agrosteril, Lerasept Spezial (zawierające jako główny składnik kwas nadoctowy) i formalinę (40-proc. formaldehyd), a także preparaty biologiczne EM-NA i EM-Bio do ograniczania wzrostu patogenicznych grzybów. Przeprowadzona walidacja stężeń preparatów chemicznych w warunkach in vitro wykazała całkowitą inhibicję wzrostu grzybni Mycogone...
Przedmiotem badań były nasiona bobu odmiany Windsor Biały pochodzące ze ścisłego doświadczenia polowego przeprowadzonego w latach 2010-2012, w którym zastosowano różne warianty ochrony biologicznej z wykorzystaniem preparatów: Polyversum WP, Bioczos BR, Biosept 33 SL. Z nasion bobu otrzymano ogółem 2053 izolatów grzybów. Niezależnie od zastosowanej ochrony do najliczniej izolowanych należały grzyby:...
