## Abstract

A synergistic fungicidal mixture contains a fungicidally effective amount of a compound of Formula I, (3S,6S,7R,8R)-8-benzyl-3-(3-((isobutyryloxy)methoxy)-4-methoxypicolinamido)-6-methyl-4,9-dioxo-1,5-dioxonan-7-yl isobutyrate, and at least one triazole fungicide wherein Formula I is

## Claims

### Claim 1

A synergistic fungicidal mixture consisting of a fungicidally effective amount of a compound of Formula I, (3S,6S,7R,8R)-8-benzyl-3-(3-((isobutyryloxy)methoxy)-4-methoxypicolinamido)-6-methyl-4,9-dioxo-1,5-dioxonan-7-yl isobutyrate, fungicide selected from the group consisting of tebuconazole, propiconazole, metconazole, and cyproconazole and, wherein the mixture is dispersed in an agriculturally acceptable adjuvant or carrier

### Claim 2 (depends on 1)

The mixture of claim 1 wherein the fungicide is tebuconazole and wherein the weight ratio of Compound I to tebuconazole is between about 1:16 and about 64:1.

### Claim 3 (depends on 1)

The mixture of claim 1 wherein the fungicide is propiconazole and wherein the weight ratio of Compound I to propiconazole is between about 1:64 and about 64:1.

### Claim 4 (depends on 1)

The mixture of claim 1 wherein the fungicide is metconazole and wherein the weight ratio of Compound I to metconazole is between about 1:4 and about 16:1.

### Claim 5 (depends on 1)

The mixture of claim 1 wherein the fungicide is cyproconazole and wherein the weight ratio of Compound I to cyproconazole is between about 1:16 and about 64:1.

### Claim 6

A method for the control and prevention of fungal attack on a plant, the method including the steps of: applying a fungicidally effective amount of a composition consisting of a compound of Formula I, fungicide to at least one of the plant, an area adjacent to the plant, soil adapted to support growth of the plant, a root of the plant, foliage of the plant, and a seed adapted to produce the plant, wherein the fungicide is selected from the group consisting of tebuconazole, propiconazole, metconazole, and cyproconazole and, wherein the mixture is dispersed in an agriculturally acceptable adjuvant or carrier prior to applying
