Clubroot disease, caused by the protist pathogen Plasmodiophora brassicae, is an emerging threat to cruciferous crops, including oilseed rape (Brassica napus L.). Most of the current commercial cultivars are highly susceptible, and efficient management tools are lacking practical implementation. Over three years and three experimental periods, we studied the effects of isotianil in comparison with Bacillus amyloliquefaciens QST713-HiCFU against clubroot disease under greenhouse experiments. Our results show control effects, which were strongly dependent on seasons, host plant genotype, and clubroot isolates: isotianil and B. amyloliquefaciens QST713-HiCFU reduced disease severity consistently at variable, but field-relevant spore concentrations of clubroot isolates; with seed treatments showing superior effects compared to drench applications. The co-application of isotianil with B. amyloliquefaciens QST713-HiCFU could, in some cases, increase the efficacy. Interestingly, all studied hybrids reacted to treatments, albeit to a somewhat different extent. When tested against a field isolate, the results obtained with the single spore isolate were partially confirmed but with greater variability. Overall, the generally positive effects of isotianil and B. amyloliquefaciens QST713-HiCFU on the reduction of clubroot were repeatedly observed. The inoculation of clubroot disease with different spore counts indicates a dose–response effect for tested products. This study highlights the importance of performing experiments holistically over multiple, consecutive seasons, with various isolates, application types, and different genetic resources of host plants.

Strawberries are an important fruit in the European diet because of their unique taste and high content of essential nutrients and bioactive compounds. The anthocyanins are known to be colorful phenolics in strawberries. In 17 samples of six strawberry cultivars produced in Serbia, i.e., the common varieties Alba, Asia, and Clery as well as promising breeding materials (11.29.11, 11.34.6, and 11.39.3), the anthocyanin profile as well as antimicrobial and antioxidative activity profiles were determined. All investigated extracts showed antioxidative and antibacterial activities against Gram-negative Aliivibrio fischeri. The responses were quite similar in number and intensity. The HPTLC−DPPH• scavenging assay and HPTLC−Aliivibrio fischeri bioassay coupled with high-resolution mass spectrometry identified pelargonidin-3-O-glucoside (Pg-3-glc) as the main anthocyanin and prominent antioxidative and antimicrobial compound in strawberries. The density functional theory calculations at the M06-2X/6-31+G(d,p) level showed that Pg-3-glc quenches free radicals via sequential proton loss electron transfer mechanism in water and in pentyl ethanoate, where the 5-OH group is the most reactive site for proton and hydrogen atom transfer. The results were confirmed via spectrophotometry. The highest total phenolic content was found in Clery and 11.39.3, while statistically significant differences between the genotypes regarding the antioxidant activity were not confirmed. Although very similar in the anthocyanin, antioxidative, and antimicrobial profile patterns, the strawberry genotypes were successfully classified using principal component analysis.
