Biopreparaty mikrobiologiczne w ochronie upraw polowych – stan obecny i perspektywy

In recent years, as a result of the introduction of the European Commission’s recommendations on limiting the use of chemical plant protection products in favor of non-chemical ones, an increase in the available range of microbial biological control agents has also been observed in field crops protection. 8 bioinsecticides and 12 biofungicides have already been registered for these crops in Poland. Strains of the entomopathogenic bacteria Bacillus thuringiensis and one strain of the entomopathogenic fungus Beauveria bassiana are mainly used to control plant pests. Strains of the antagonistic fungi Trichoderma harzianum and Trichoderma asperellum, the hyperparasitic fungus Coniothyrium minitans and the fungus-like organism Pythium oligandrum are used to control plant disease. The bacterium Pseu­domonas sp. is also used, and the bacterium Bacillus amyloliquefaciens has been registered for dressing. Intensive scientific research is currently underway to improve the effectiveness of biological control agents. Innovative formulations are being created to increase their efficacy and extend the storage period. The future will also include plant protection programs with the combined use of beneficial mi­croorganisms and macroorganisms. This publication presents currently available microbiological plant protection products used in field plant protection, analyzes current and future research on their use and improvement of formulations.
