A chemical study of the reactive species is liquid phase will be presented, before comparing the efficiency of Pythium Ultimum deactivation in liquid phase following different plasma treatments. This efficiency will first be analysed with the use of inoculated distilled water ELISA essay, followed by a hyphal mass growth comparison in dextrose broth medium over the period of 1 week post treatment. Further proof of pythium inactivation is investigated with SEM imaging and the plausible chemical pathways for inactivation are discussed.
