Some products and substances admitted to be used in organic farming were examined regarding their suitability for sugar beet seed dressing. Seeds of sugar beet variety Poljana were treated with plant oils (thyme and tea tree oil) and commercial products used for plant protection in organic farms: Bioczos, Biochikol, Biosept and Sinocin. The control combinations were untreated seeds and also seeds treated with conventional mordant Funaben T to compare the efficiency of the treatments. During the field emergence a toxic effects of Bioczos, undiluted thyme oil and to a less degree of tea tree oil on sugar beet seeds were observed. 2 months after the field emergence and during the harvest the highest field stand was obtained from the seeds dressed with Biosept, Biochikol and Funaben T. The numbers of plants grown from seeds treated with tea tree oil and Sinocin were similar to those from untreated seeds. Most of the used substances seemed to protect plants during all the vegetation period. Sugar beet seed dressing with FunabenT, Biochikol and tea tree oil improved the root yield. Moreover seed treatment with Biochikol, Biosept and Sinocin stimulated the development of sugar beet leaves
