The aim of this study was to establish the possibility of using different forms of the Effective Microorganisms preparation to limit the occurrence of the fungal diseases of the strawberry leaves and fruits and estimation of their infl uence on the growth, crop and quality parameters of the fruits. The EM preparation effectively limited the occurrence of strawberry red-leaf spot (Diplocarpon earliana) and white-leaf spot (Mycosphaerella fragariae) and to a lesser extent – the powdery mildew on the fruits (Botrytis cinerea). From the studied forms of the EM preparation, the best effects were achieved when plants were sprayed with the mixture of two forms EM-A and EM-5 and the EM-5 preparation enriched with the onion extract. In combination with their application the plants had a high diameter increment of the collar root, the highest weight of the root system and a high average mass of the fruits. No signifi cant infl uence of different forms of Effective Microorganisms on the quality parameters of the fruits was shown.
