Abstract

One of the main diseases currently affecting wheat crops is head blight, caused by the fungus Fusarium graminearum Schwabe, which reduces yield. A promising alternative for control is the use of essential oils. The objective of this study was to evaluate the in vitro antifungal activity of essential oils and a fungicide based on trifloxystrobin and prothioconazole on the mycelial growth of Fusarium graminearum. The experiment was conducted at the Phytopathology Laboratory of Unicruz-Cruz Alta, Rio Grande do Sul. The experimental design was completely randomized, with treatments consisting of a combination of essential oils, fungicide, and control. The relationship between mycelial growth of the colony, the inhibition percentage, and the growth rate of  F. graminearum were evaluated. Essential oils of rosemary, star anise, and eucalyptus globulus, and the fungicide based on trifloxystrobin and prothioconazole, were effective in controlling Fusarium graminearum in vitro.
