| Popis: | Bioformulations containing microorganisms that have various useful properties for plants are widely used as an alternative to chemical pesticides. Methods for evaluating the quality of such biological products have not yet been standardized. Composition of bioformulations used for protecting plants and stimulating plant growth was studied with molecular methods. Toxicity of bioformulations was evaluated on laboratory populations of bumblebees (Bombus terrestris L.). The number of bacteria in the two bioformulations was significantly less than the manufacturer’s stated. The declared composition of microorganisms in 33% of bioformulations did not fully or partially correspond to the identified composition. Klebsiella sp. and Citrobacter sp. bacteria were found among non-target bacteria. It is known that some species of these bacteria genera are opportunistic for humans. Not one of the studied bioformulations did not cause the death of bumblebees. However, it was found that 5 bioformulations out of 18 reduced the flight activity of bumblebees, which indicates their toxic effect. The data obtained by us shows that it is necessary to develop standardized methods for assessing the quality and safety of microbiological bioformulations that are available for public sale. |
