The use of synthetic fungicides is still the most effective protection against phytopathogenic fungi. However, the excessive and long-term use of fungicide can lead to many adverse side effects such as adverse effects on human health, environmental pollution and pathogen resistance. Biological compounds extracted from plants, such as essential oils, do not have any adverse effects on humans and the environment so they can be one of the most important alternatives to synthetic fungicides. Essential oils are secondary metabolites of plants that often possess antifungal, antibacterial, insecticidal, antiviral and nematocidal properties. The chemical composition and the biological effect of essential oils is complex and dependent on the type of a plant, the part of the plant it is taken from, its origin, pedoclimatic conditions, harvest time, harvesting season and processing conditions, storage conditions, type of pathogen, amount applied and application. Therefore, many in vitro and in vivo studies of antifungal activity of essential oils to various fungopathogenic fungi are carried out in order to find essential oils or combinations thereof whose inhibitory growth potential of phytopathogenic fungi is comparable to synthetic fungicides.
