W doświadczeniach przebadano skuteczność preparatów biotechnicznych: Bioczos BR, Biochikol 020 PC i Biosept 33 SL oraz porównawczego Amistar 250 SC, w hamowaniu rozwoju grzybni in vitro oraz procesu gnicia materiału roślinnego (kiełki ziemniaków, korzenie marchwi) in vivo przez Rhizoctonia solani i Sclerotinia sclerotiorum. W przypadku R. solani najskuteczniej hamował rozwój grzybni Biosept 33 SL, najsłabiej Bioczos BR, zaś Biochikol 020 PC działał stymulująco. Podobne działanie stwierdzono w warunkach in vitro dla S. sclerotiorum. W doświadczeniach in vivo najskuteczniejszym w hamowaniu rozwoju zgnilizny kiełków (R. solani) okazał się Amistar 250 SC oraz nieco słabszym Biochikol 020 PC i Biospet 33 SL, zaś najsłabszym Bioczos BR. W przypadku S. sclero- tiorum najskuteczniej chronił korzenie przed zgnilizną Amistar 250 SC, nieco słabiej Biospet 33 SL i znacznie słabiej Biochikol 020 PC (60 %) i Bioczos BR (37 %).

Among the tested biotechnical preparations: Biochikol 020 PC, Biospet 33 SL, Bioczos BR and standard fungicide Amistar 250 SC, in laboratory conditions (poisoned medium) and on plant material, it turned out that in the case of Rhizoctonia solani most effective in inhibiting the development of mycelium was Biospet 33 SL, and on the plant material Biochikol 020 PC, the weakest in both experiments was Bioczos BR. In the case of Sclerotinia sclerotiorum most effective in inhibiting the development Biosept 33 SL and Amistar 250 SC, and weakest in both cases was Bioczos BR.

The presented paper estimates the reaction of grain maize to the foliar application of Biochikol 020 PC biostimulator. In the years 2005–2007, on a light soil, four experimental plots were compared: A – control; B – 2x Biochikol 020 PC; C – set of foliar fertilizers Ekosol (3 sprayings); D – 2x Biochikol 020 PC + Ekosol (treatments I and III applied together). Biostimultor Biochikol 020 PC, as well as the studied set of foliar fertilizers of Ekosol type did not exert any influence on the course of maize vegetation, on the plant quantity and on the development of their ears. Also, no effect was found to be exerted on the grain yield and on any changes in the grain moisture and its yield. The studied experimental plots did not show any occurrence of pests or maize diseases.

Obumierające łuski żywotnika zachodniego są miejscem występowania różnych gatunków i form grzybów. Najczęściej izolowanym gatunkiem był grzyb Pestalotia funerea, nieco rzadziej stwierdzono obecność Fusarium avenaceum i Kabatina thujae. Znaczna część izolowanych grzybów wykazywała uzdolnienia patogeniczne. Zdolność zakażania pędów wykazywały izolaty: Kabatina thujae oraz Pestalotia funerea. Patogeniczne w stosunku do łusek żywotnika były grzyby: Botrytis cinerea, Diplodia thujana, Fusarium avenaceum, Fusarium culmorum, Kabatina thujae, Pestalotia funerea oraz Pleospora herbarum. Najwyższą aktywność fungistatyczną z badanych preparatów biotechnicznych w stosunku do wybranych grzybów patogenicznych żywotnika zachodniego wykazywał preparat Biosept 33 SL.

The dying-off hulls of Thuja occidentalis are the seat of various fungi species and forms. The fungus Pestalotia funerea was isolated most frequently, while the presence of Fusarium avenaceum and Kabatina thujae fungi was determined rarely. Large amount of isolated fungi showed pathogenic abilities. The abilities to infect the shoots were demonstrated by the isolates: Kabatina thujae and Pestalotia funerea. The fungi: Botrytis cinerea, Diplodia thujana, Fusarium avenaceum, Fusarium culmorum, Kabatina thujae, Pestalotia funerea and Pleospora herbarum were pathogenic to white cedar leaves. From among the biotechnic preparations under investigation the highest fungistatic activity to selected pathological fungi of white cedar was shown by Biosept 33 SL.

In 2008–2009 the studies were performed on the efficacy of selected plant protection used to control of cereal diseases in organic farms in Poland. Observations were carried out three times in the vegetation season for winter wheat and twice for spring wheat. The identification at pathogenic fungi isolated from wheat were carried out using the Petri dish method and re-isolation of grown fungi was carried out on potato-glucose PDA medium. Fungi species were identified with the use of available monographs and identification keys.

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.

The aim of two year field investigations was to evaluate the effect of seed-potato dressing and plants spraying treatments with biotechnical preparations (Biosept 33 SL – a.s. extract of grapefruit, Biochikol 020 PC – a.s. chitosan) on infection of potato tubers by Rhizoctonia solani and Helminthosporium solani. As a standard fungicide Vitavax 2000 FS (a.s. karboxin and thiuram) was used. During the vegetation period applied biotechnical preparations lowered both the deegre of tuber infection and percentage share of infected tubers by R. solani and H. solani.
