Biological activity of chitosan in the form of a microcrystalline gel and of a hydrogel, as well as the activity of grapefruit extract were evaluated in vitro by means of measuring the growth inhibition and formation of morphological structures of four isolates of Seimatospo- rium hypericinum, obtained from leaves and stems of St. John's wort (Hypericum perforatum). In addition, the effect of acybenzolar S-methyl was tested in climatic chamber conditions, when plants inoculated by S. hypericinum were protected. The studies carried out in vitro showed that both chitosan and grapefruit extract inhibited growth of pathogen colonies significantly. The studies confirmed the protective effect of chitosan, grapefruit extract and acybenzolar S-methyl in the case of St. John's wort plants inoculated by S. hypericinum. Chitosan and grapefruit extract proved to be the most effective when used preventively.

In presented studies was undertaken the attempt to determine the effectiveness of such preparations as Biochikol 020 PC and Biosept 33 SL in limiting the growth of T myrtilli in vitro. Moreover, the protective effect of these biopreparations and Dithane M45 80WP for highbush blueberry stems was determined. The studies carried out in vitro indicated that Biochikol 020 as well as Biosept 33 SL significantly limited the growth and development of pathogen. Very strong inhibition of hyphae growth and its deep degradation were caused by Biosept 33 SL in concentration 0.3%. Similarly, in experiment on protecting action of selected preparations for stems of highbush blueberry against T. myrtilli, Biochikol 020 and Biosept 33 SL inhibited the growth of pathogen. But its protective effects were weaker in comparison to Dithane M45 80WP because after the application of this preparation the development of disease symptoms caused by T. myrtilli was significantly lower.
