The aim of this study was to test the efficacy of some biological preparations and plant oils in the suppression of oak mildew as potential components of the mixture with the biological insecticide D-Stop, aiming at the synchronic, combined suppression of oak mildew (Microsphaera alphitoides) and Gypsy moth (Lymantria dispar L.). The tests of the biopreparations for the suppression of mildew, which have fungicide or fungistatic effects (Supresivitm Ibefungin) in forestry didi not show satisfactory effects. However, the promising results were obtained with the preparation Bion 50 WG and soybean oil. Along with the satisfactory biological efficcacy, these compounds were not phytotoxic to the cultivated plants, so it is supposed that, by their combination with the microbiological insecticide D-Stop, it would be possible to suppress simultaneously the Gypsy moth and mildew - biotically harmful factors which can occur at the same time on oak foliage. In the future research, soybean oil will be favoured, as it has multiple uses. As it is a product for human nutrition, it is not on the Positive List of Poisons, i.e. it is not ecotoxic and it is safe for application.
