EFFECT OF PULSED ELECTRIC FIELD ON VIABILITY OF FUSARIUM MICROMYCETES

Original language description

Fusarium species are one of the most studied fungal pathogens of cereals. They cause Fusarium head blight or stem base diseases that are risky not only in terms of yield losses but also due to mycotoxins production. Several strategies are used to prevent Fusarium colonisation of plants, including fungicide treatment. However, according to the EU Biodiversity Strategy for 2030, the use of fungicides needs to be reduced. Therefore, alternative seed treatments should be sought. One possible method is the use of a pulsed electric field (PEF) that could kill or remove the fungi from the surface. We first investigated the sensitivity of fungi to PEF treatment. Spore suspensions of four Fusarium species (F. culmorum, F. graminearum, F. poae, F. sporotrichioides) were treated in continuous PEF-system (OMNIPEF; VITAVE, Czech Republic) (10 kV/cm, 450-900 Hz). Spore viability was assessed on an artificial medium.
