Fusarium head blight (FHB) is a serious disease of wheat and‎barley that leads to significant economic losses and deteriorated‎grain quality because of the associated mycotoxins. Genetic resistance‎and use of fungicides are the methods used to control‎FHB. However, in weather conditions conducive for FHB epidemics,‎higher levels of genetic resistance as well as greater‎efficacy of fungicides are required to adequately control this‎disease. Due to the extensive use of a single mode of action for‎management of FHB, there is a need to diversify fungicides used‎to lower the risk of resistance development in pathogen populations.‎In this 2-year study, we evaluated the performance of a‎new fungicide, Miravis Ace (a proprietary mix of pydiflumetofen‎and propiconazole active ingredients produced by Syngenta) for‎controlling FHB. It is a mix of succinate dehydrogenase inhibitor‎and demethylation inhibitor fungicides and can add diversity to‎the fungicide toolkit for FHB management. The level of control‎of FHB and deoxynivalenol (DON) achieved by spraying Miravis‎Ace at anthesis (Feekes growth stage 10.5.1) was found to be‎equivalent to that provided by the currently recommended‎products for managing FHB and reducing DON in wheat and‎barley.
