Abstract

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 tebuconazole, prothioconazole, difenconazole, epoxiconazole, mefentrifluconazole, benzovindiflupyr, penthiopyrad, fluxapyroxad, bixafen, fluopyram, picoxystrobin, pyraclostrobin, azoxystrobin, mancozeb and chlorothalonil, provides synergistic control of selected fungi.

Claims (12)

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 tebuconazole, prothioconazole, difenoconazole, epoxiconazole, and mefentrifluconazole.

2. The mixture of claim 1 wherein a concentration ratio of the compound of Formula I to tebuconazole is from about 2:1 to about 1:4.

3. The mixture of claim 1 wherein a concentration ratio of the compound of Formula I to prothioconazole is from about 1:6.4 to about 1:52.

4. The mixture of claim 1 wherein a concentration ratio of the compound of Formula I to difenoconazole is from about 2:1 to about 1:2.

5. The mixture of claim 1 wherein a concentration ratio of the compound of Formula I to epoxiconazole is from about 4:1 to about 1:2.

6. The mixture of claim 1 wherein a concentration ratio of the compound of Formula I to mefentrifluconazole is from about 4:1 to about 1:2.

7. The mixture of claim 1 , wherein the mixture provides control of a fungal pathogen, and the pathogen is the causal agent of leaf blotch of wheat (Zymoseptoria tritici ).

8. A synergistic, fungicidal composition comprising of a fungicidally effective amount of a mixture of claim 1 and an agriculturally acceptable carrier.

9. A method of treating a plant for control of a fungal pathogen, wherein the mixture of claim 1 is applied to one of the plant, foliage of the plant, a plant seed, and an area adjacent to the plant.
