## Abstract

The present invention is directed to an agricultural composition comprising a protoporphyrinogen oxidase (PPO) inhibitor, one or more sugar alcohols and optionally, one or more auxin herbicides. The present invention is further directed to a method of controlling weeds comprising applying concurrently or sequentially a PPO inhibitor and one or more sugar alcohols, and optionally one or more auxin herbicides to the weeds or an area in need of weed control.

## Claims

### Claim 1

An agricultural composition comprising a protoporphyrinogen oxidase (PPO) inhibitor and one or more sugar alcohols, wherein presence of the one or more sugar alcohols in the composition improves weed control by the PPO inhibitor by at least 10% over the PPO inhibitor alone and wherein the PPO inhibitor is selected from the group consisting of ethyl [3-[2-chloro-4-fluoro-5-(1-methyl-6-trifluoromethyl-2,4-dioxo-1,2,3,4-tetrahydropyrimidin-3-yl)phenoxy]-2-pyridyloxy]acetate, flumioxazin, lactofen, fomesafen, saflufenacil, sulfentrazone and trifludimoxazin.

### Claim 2 (depends on 1)

The composition of claim 1, wherein the PPO inhibitor is ethyl [3-[2-chloro-4-fluoro-5-(1-methyl-6-trifluoromethyl-2,4-dioxo-1,2,3,4-tetrahydropyrimidin-3-yl)phenoxy]-2-pyridyloxy]acetate.

### Claim 3 (depends on 1)

The composition of claim 1, wherein the one or more sugar alcohols is selected from the group consisting of D-mannitol, D-sorbitol, maltitol, erythritol, L-arabitol, xylitol, 1D-chiro-inositol, inositol, myoinositol, galactinol, L-quebrachitol, D-pinitol, D-ononitol, and D-myo-inositol-1,3-diphosphate.

### Claim 4 (depends on 3)

The composition of claim 3, wherein the one or more sugar alcohols is D-sorbitol.

### Claim 5 (depends on 1)

The composition of claim 1, further comprising one or more auxin herbicides.

### Claim 6 (depends on 5)

The composition of claim 5, wherein the one or more auxin herbicides is selected from the group consisting of dicamba, 2,4-D, dichloroprop, (4-chloro-2-methylphenoxy)acetic acid (MCPA), 4-(4-chloro-2 methylphenoxy)butanoic acid (MCPB), mecoprop, picloram, quinclorac, triclopyr, fluroxypyr, picloram, aminopyralid, clopyralid and aminocyclopyrachlor and agricultural acceptable salts and esters thereof.

### Claim 7 (depends on 6)

The composition of claim 6, wherein the one or more auxin herbicides is a salt of dicamba.

### Claim 8 (depends on 7)

The composition of claim 7, where in the salt of dicamba is selected from the group consisting of dicamba-biproamine, dicamba-diglycolamine, and dicamba-tetrabutylamine.

### Claim 9

A method of controlling weeds comprising applying concurrently or sequentially a protoporphyrinogen oxidase (PPO) inhibitor and one or more sugar alcohols to the weeds or an area in need of weed control, wherein presence of the one or more sugar alcohols in the composition improves weed control by the PPO inhibitor by at least 10% over the PPO inhibitor alone and wherein the PPO inhibitor is selected from the group consisting of ethyl [3-[2-chloro-4-fluoro-5-(1-methyl-6-trifluoromethyl-2,4-dioxo-1,2,3,4-tetrahydropyrimidin-3-yl)phenoxy]-2-pyridyloxy] acetate, flumioxazin, lactofen, fomesafen, saflufenacil, sulfentrazone and trifludimoxazin.

### Claim 10 (depends on 9)

The method of claim 9, further comprising applying concurrently or sequentially one or more auxin herbicides to the weeds or an area in need of weed control.

### Claim 11 (depends on 9)

The method of claim 9, wherein the PPO inhibitor is applied at a rate from about 1 to about 100 grams per hectare.

### Claim 12 (depends on 9)

The method of claim 9, wherein the PPO inhibitor is applied at a rate from about 10 to about 50 grams per hectare.

### Claim 13 (depends on 9)

The method of claim 9, wherein the PPO inhibitor is applied at a rate of 20 grams per hectare.

### Claim 14 (depends on 9)

The method of claim 9, wherein the one or more sugar alcohols is applied at a rate of about 100 to about 100,000 grams per hectare.

### Claim 15 (depends on 9)

The method of claim 9, wherein the one or more sugar alcohols is applied at a rate of about 1,000 to about 30,000 grams per hectare.

### Claim 16 (depends on 9)

The method of claim 9, wherein the one or more sugar alcohols is applied of about 6,800 grams per hectare.

### Claim 17 (depends on 10)

The method of claim 10, wherein the one or more auxin herbicides is applied at a rate of about 1 to about 1,000 grams per hectare.
