Abstract

Colletotrichum gloeosporioides is the etiologic agent of several diseases in fruit trees worldwide. In passion fruit the fungus causes anthracnose disease that attacks the all plant parts, especially ripe fruits. With regard to food and environmental security, the management of this pathogen should include only natural products of low risk to the ecosystems balance. In this context, the objective of the present study was to verify the in vitro sensitivity of C. gloeosporioides to essential oils. The antimicrobial activity of essential oils was screened using the disk diffusion method and broth micro dilution. The minimum inhibitory concentration (MIC) and the minimum fungicidal concentration (CFM) were determined. The MIC varied from 160 to 5 μL / mL in the different essential oils, with basil and cinnamon cassia being those that reached the lowest concentrations. The essential oils of tea tree, citronella, mint arvensis and thyme showed fungistatic action. Excellent results were obtained in determining the CFM for cinnamon cassia essential oils (10 μL / mL), ginger (80 μL / mL), basil (160 μL / mL) and sweet orange (160 μL / mL).
