The aim of this study was to assess the possibility of improving the health of dill (Anethum graveolens L.) and fennel (Foeniculum vulgare var. azoricum Mill.) seeds, grown in ecological systems and using bio-stimulators. The results indicate the high performance of the used biological compounds, applied to seeds and plants. The tested compounds induced dill and fennel plant resistance to disease, resulting in a decreased infestation of the reproduced seeds by microflora. The highest efficacy in reducing seed infestation by microflora showed Physpe and Tytanit. Health status of dill and fennel seeds, obtained from plants treated with the mentioned compounds, was significantly higher than of seeds obtained from plants untreated or treated with Goemar Goteo and Biojodis. The compounds applied to seeds and plants improved germination of seeds of both plant species. These data demonstrate the usefulness of the used biological compounds, Physpe, Goemar Goteo, Biojodis and Tytanit, in dill and fennel production of seeds, in order to improve their health status and the seed value.
