Differential susceptibility of Fusarium oxysporum f. sp. conglutinans isolates to essential oils according to pathotype and geographical origin

Original language description

Fusarium oxysporum f. sp. conglutinans is responsible for yellow wilt, a serious disease of cabbage. This study evaluates the inhibitory effects of six essential oils (oregano, thyme, clove, cinnamon, lemongrass, litsea) at different concentrations on eight isolates of different origins. Our investigation involved the use of multicriteria discriminant analysis to evaluate the results with respect to the common effects of all essential oils. Differences in inhibition rates between isolates and essential oils were examined using the Kruskal-Wallis test. Probit analysis was used to determine EC50 values, which revealed significant efficacy of oregano oil. The essential oils tested showed clustering based on the content of the primary constituents ( oregano and thyme, clove and cinnamon, lemongrass and litsea), a classification that is somewhat consistent with their inhibitory potential. The response of the isolates to the oils varied considerably and showed more differences within groups of isolates than between races. Our findings suggest that sensitivity to essential oils may be more related to the geographic origin of the isolates than to their race.
