Abstract: The present invention relates to phytosanitary compositions with fungicidal properties that comprise a mixture of essential oils obtained from plants and agents with known fungicidal properties, such as alkali metal or ammonium bicarbonates, and compounds based on copper or the salts thereof, for use, principally, in contact-protection against fungal infections in cultivated plants and post-harvest, and also in other antifungal applications. In said compositions, the effect of the agents that have known fungicidal properties is potentiated synergistically by the aforementioned essential oils. The present invention also relates to the use of said essential oils as potentiators for agents with known fungicidal properties.

Abstract: The present invention relates to a composition with fungicidal and bactericidal activity, which comprises volatile organic compounds (VOCs) obtained from plants and microorganisms, in which said VOCs are C4-C12 fatty alcohols or cyclic alcohols or phenol-derived compounds, or terpene-derived compounds, and also derivatives and mixtures thereof. Furthermore, the present invention likewise relates to the use of said compositions in the protection of agricultural crops, in post-harvest treatments, in food preservation and in the disinfection of facilities and equipment.
