The invention concerns a method for producing an antibacterial preparation using atmospheric cold plasma generated in a continuous dc-APGD flow system. In this process, tap water with Lugol’s solution (172 μL per 1 dm³ of water) is used as the flowing liquid cathode.
The resulting preparation contains reactive nitrogen species and elevated molecular iodine levels, providing strong antimicrobial activity against plant pathogens such as Pectobacterium atrosepticum, Pseudomonas syringae, P. corrugata and P. savastanoi. The technology does not require deionised water or long processing times, and the flow-through setup enables fast and energy-efficient production.
The invention also includes the preparation itself and the dedicated flow-through reaction-discharge system used for its generation.
- Control of bacterial plant pathogens in field and greenhouse cultivation,
- Disinfection of seeds and propagation material,
- Reduction of yield losses caused by bacterial infections.
