Description of the research topic:
Ecologically informed solutions are an important tool for pathogen and pest management as well as nutrient supply in environmentally friendly, sustainable crop production. Of these, technologies based on biocontrol agents (BCA) stand out, in which - in addition to their pest-suppressing effect - the nutrient unfolding / mobilizing effects of the microbes also prevail. Currently, commercially available formulations are based on the activity of soil-borne microbes (PGPR, PGPF), while we have little information about the practical application of epiphytic and endophytic microorganisms that have a plant growth-promoting effect and that can be identified - through their bioactive metabolites (e.g. surfactins, iturines, fengycins) - as biocontrol agents of foliar pathogens. Chitosan, that can be extracted - in addition to crustaceans and mussels - also from fungi, was approved by the EU in 2014 to increase the disease resistance of plants.
Foliar plant conditioning products containing both bioactive metabolites and chitosan nanoparticles in addition to the living microorganisms, can provide new possibilities for biological plant protection, as well as foliar fertilization. In addition to organic farming, their use may also be justified in conventional crop production, given the increasing numbers of synthetic pesticides withdrawn from the market due to their harmful effects.
The research program includes the selection of combinations of microorganisms - bioactive metabolites - chitosan nanoparticles suitable for practical use, and their extensive testing under greenhouse and field conditions.
