In view of the fact that recently the possibilities to use chemical treatment have been limited it is necessary to research the usefulness of seed treatment products composed from natural substances in the form of an extract or mycorrhizal mycelium, bacteria, etc. The aim of the research was to assess the usefulness of plant substances and substances containing microorganisms for oats seed treatment. Several preparations which might be useful for the treatment of oats seeds or the seeds of other cereals were researched in a pot experiment. The seeds of hulled and hulless oats were treated with the following substances: Biosept 33 SL (grapefruit extract), Liquid Bioczos (garlic extract), Timorex Gold 24 EC (tea plant extract), Polyversum (Pythium oligandrum fungus) and Click Horto (mycorrhizal mycelium – Globus intraradius, rhizosphere bacteria, Trichoderma atraviride fungus). The health of seedlings and fresh mass of the aboveground part and roots were analysed. The seeds were treated with those preparations by being soaked in their solutions. The preparations had positive influence on the emergence of crops. Bioczos, Biosept 33 SL and Polyversum also improved the health of emerging oats seedlings. Click Horto biostimulated the development of oats. The combination with this preparation resulted in a noticeable growth in the root mass and aboveground part. The research provides information which of the preparations under analysis may be useful for the treatment of seeds of oats cultivars.

Integrated pest management is actually the main direction taken in the cultivation of agricultural crops in the European Union. In accordance with its principles it is necessary to combine all available methods of reducing the occurrence of pests to a level where they do not cause losses of economic importance. Great emphasis is placed on the rational use of plant protection products and its selectivity. Essential is the large knowledge of the effectiveness of individual active ingredients and dosages in which they achieve the greatest efficacy. The aim of the experiment was to determine the possibility of using lower doses (than those registered in Poland) of fungicides in wheat cultivation in comparison to full doses. In BBCH 75 stage (medium milk) stem-base assessment was performed to confirm the effectiveness of mentioned above fungicides against eyespot of cereals (Oculimacula spp.) and Fusarium foot rot (Fusarium spp.). Application of fungicides in BBCH 31 stage in both doses (registered and reduced) allowed to obtain higher yields in comparison to non protected plots in two years of experiment.
