Synergistic mixtures for fungal controls in cereals
A fungicidal composition containing a fungicidally effective amount of the compound of Formula I, (S)-1,1-bis(4-fluorophenyl)propan-2-yl (3-acetoxy-4-methoxypicolinoyl)-L-alaninate, and at least one fungicide selected from the group consisting of epoxiconazole, prothioconazole, azoxystrobin, pyraclostrobin, fluxapyroxad, benzovindiflupyr, and chlorothalonil, provides synergistic control of selected fungi.
1. A synergistic fungicidal mixture, comprising: a fungicidally effective amount of the compound of Formula I, (S)-1,1-bis(4-fluorophenyl)propan-2-yl (3-acetoxy-4-methoxypicolinoyl)-L-alaninate:
and
at least one additional fungicide selected from the group consisting of epoxiconazole, prothioconazole, azoxystrobin, pyraclostrobin, benzovindiflupyr, fluxapyroxad, and chlorothalonil.
