Origanum vulgare ssp. hirtum Essential Oil as Inhibitors of Fusarium Dry Rot of Potato

Fusarium dry rot on potato, caused by the fungal pathogen solani, is characterized an internal light to dark brown or black and usually of potato tubers. The disease progresses noticeably faster during latter half storage season. Biological control intriguing concept, but currently, no products are available commercially. It was found that essential oil a number Lamiaceae species, including oregano, have strong biocidal properties. A significant antifungal activity Origanum vulgare ssp. hirtum against different phytopatogens in vitro experiments has been demonstrated. In this study, effect oregano tubers infected with solani evaluated. For purpose, slices cut at thicknesses 8–10 mm were inoculated mycelium plugs F. center slices. tested using two approaches: contact air impact. first approach, applied as aqueous solution concentration range 1–3 µg/mL tuber second placed Petri dishes amounts from 5 50 µL without between them. reduction micellar growth tissue observed impact application 25 μL higher. result showed shows potential for rooms tubers, especially last
