Abstrakt:	The chemical composition of Essential Oils Satureja montana and Mentha longifolia was determined, and their activity against important phytopathogenic and post-harvest fungi was studied, to evaluate their potential as natural food preservatives. The major compounds were carvacrol (24.0%), γ-terpinene (15.9%) and p-cymene (14.2%) in S. montana , and piperitenone oxide (52.7%) and piperitone oxide (23.5%) in M. longifolia . EOs were tested in vitro on Alternaria alternata , Botryotinia fuckeliana , Curvularia hawaiiensis , Fusarium equiseti , F. oxysporum lycopersici , Rhizoctonia solani and Verticillium dahliae . S. montana demonstrated excellent results. At 300 μg mL -1 the growth of all fungi was inhibited with 100% mycelial growth inhibition (MGI), except for B. fuckeliana (92%). M. longifolia was less effective, and its best result was against Verticillium dahliae (100% MGI) at 400 and 300 μg mL -1 . S. montana EO was selected for in vivo antifungal tests in Cherry tomatoes and kaki "Persimmon" against A. alternata . The S. montana EO biofilm reduced post-harvest fungi development. In tomato, it inhibited up to 90% after 20 days. Necrosis did not occur for 2 months in the persimmon fruits. S. montana EO is an effective non-toxic preservative that can be considered to develop a botanical and enviro-friendly low-risk biofungicide. (© 2019 The Author(s).)
