Abstract: The experiments were carried out on 5 different bioproducts for control of Verticillium longisporum in oilseed rape. For in vitro trials, greenhouse trials and field trials, the bioproducts used were based on bacteria (Bacillus amyloliquefaciens, Pseudomonas veronii) and fungi (Pythium oligandrum, Trichoderma asperellum, Coniothyrium minitans). In in vitro trials, some products (based on Trichoderma asperellum) showed a 100% inhibition effect on the pathogen for a whole trial period of 45 days. The greenhouse trial showed significant differences in bioproducts effectiveness (P < 0.00723) compared to control. Three bioproducts (based on Coniothyrium minitans, Trichoderma asperellum and Pseudomonas veronii) showed a 100% inhibition effect against the pathogen. In field trials conducted in 3 locations, there were some differences in yield, which can be important for growers and practice use. The highest yield (19.1% higher than the control) was achieved with a bioproduct based on Trichoderma asperellum. In trials, it is possible to see that there are promising results that can be used for further testing.
