Effect of Essential Oil Components on the Growth Inhibition of Fusarium solani var. coeruleum During Potato Storage

Abstract: Fusarium dry rot of potato may be caused by several species of the genus Fusarium. This study aimed to evaluate the effect of essential oil (EO) components (α-pinene, carvacrol, cinnamaldehyde, D-carvone, eucalyptol, L-linalool, L-menthol, L-menthone, (R)-(+)-limonene and thymol) on the growth of Fusarium solani var. coeruleum using in vitro and in vivo experiments. All the evaluated EO components had a significant effect on the pathogen growth inhibition. Under in vitro conditions, the strongest inhibitory effect on mycelial growth was recorded for carvacrol, thymol, L-menthol and cinnamaldehyde. In vivo experiments confirmed the efficacy of selected EO components. The application of EO components was done by tuber dressing and fumigation. After treating tubers with EO components by dressing and fumigation, a statistically highly significant reduction in tuber infection with the pathogen was observed. Dressing usually had a stronger effect on the reduction in pathogen tuber infection (56.07–81.44%) compared to fumigation (40.03–69.63%). EO components did not have any significant effect on the organoleptic characteristics of cooked tubers; however, during tasting, a deteriorated quality of EO component-dressed tubers was found due to the off-odor and taste of the applied EO components. EO components have a high potential for ecological tuber protection against F. solani var. coeruleum during storage.
