The objective of this work was to evaluate the antifungal activity of essential oils (OEs) of mint (Mentha piperita L.), green peppermint (Mentha spicata L.) and peppermint arvensis (Mentha arvensis L.) in the growth of Aspergillus sp. and Penicillium sp., and in the physiological and sanitary quality of seeds of Phaseolus vulgaris L. cv. Tuiuiu. For each essential oil (OE), concentrations of 0.5; 1.0 and 1.5%. The fungicide Derosal Plus® it is constituted the positive control at the dose

The variables analyzed were mycelial growth, sporulation, percentage of germination, blotter test, rate of emergence (IVE), shoot length and primary root, total fresh biomass, dry shoot and root biomass. Mentha OEs totally inhibited mycelial growth and fungal spore production. Mentha OEs had an inhibitory effect on seed germination and IVE, as well as reducing shoot length in bean plants. On the other hand, the oils did not affect the attributes total fresh biomass, dry shoot biomass, as well as the length of the primary root. Regarding sanity, all treatments promoted a lower incidence of fungi Aspergillus spp.; Alternaria spp.; Cladosporium spp. Colletotrichum spp., Fusarium spp. and Penicillium spp. when compared to the negative control.
