3Pathogen resistance to Plant Protection Products

The problem of pathogens’ resistance to commercial pesticides is a widely known fact. Currently selected resistance mutations, e.g. against septoriosis, can occur in up to 70% of crop area.

Therefore, the phenomenon of pathogens’ resistance continues to be a growing problem in agriculture. Climate change is another factor that influences the spread of plant diseases. It manifests in increasing frequency of outbreaks and the spread of pests in new environments. Changes in temperature and rainfall contribute to the faster evolution of new and more aggressive pest strains. This requires the use of even more pesticides to combat this issue and, in turn, producing even more highly resistant pathogens.

However, using biopreparations poses no risk for development of pathogenic resistance. This risk is typical for synthetic plant protection products and fertilizers, but not seen with biopesticidal products.
