## Abstract

Herbicidal injury that might otherwise be caused by 4-amino-3-chloro-6-(4-chloro-2-fluoro-3-methoxyphenyl)pyridine-2-carboxylic acid and agriculturally acceptable salt, ester, and amide derivatives thereof in cereal crops is reduced by concomitant application of florasulam.

## Claims

### Claim 1

A method of protecting cereal plants from the harmful effects of a first herbicide which is the compound of the formula (I)
or an agriculturally acceptable salt, ester or amide derivative thereof, which comprises: concomitantly applying the first herbicide and florasulam to the cereal plant or to an area intended for cultivation of cereal plants.

### Claim 2 (depends on 1)

The method of claim 1, wherein the first herbicide is applied at a rate of from about 2.5 to about 35 g ae/ha, and the florasulam is applied at a rate of from about 2.5 to about 10 g ai/ha.

### Claim 3 (depends on 1)

The method of claim 1, wherein the first herbicide is applied at a rate of from about 5 to about 35 g ae/ha, and the florasulam is applied at a rate of from about 5 to about 10 g ai/ha.

### Claim 4 (depends on 1)

The method of claim 1, wherein the first herbicide is the methyl ester or the triethylamine (TEA) salt of the compound of formula (I).

### Claim 5 (depends on 4)

The method of claim 4, wherein the methyl ester or TEA salt is applied at a rate of from about 2.5 to about 10 g ae/ha.

### Claim 6 (depends on 4)

The method of claim 4, wherein the methyl ester or TEA salt is applied at a rate of from about 5 to about 10 g ae/ha.

### Claim 7 (depends on 1)

The method of claim 1, wherein the cereal plant is wheat, barley, or tame oats.

### Claim 8 (depends on 1)

The method of claim 1, wherein the first herbicide and florasulam are applied together.

### Claim 9

A composition for protecting cereal plants from the harmful effects of a first herbicide which is the compound of formula (I)
or an agriculturally acceptable salt, ester or amide derivative thereof, which comprises: said first herbicide in combination with florasulam in a weight ratio of about 2:1 to about 1:2.

### Claim 10 (depends on 9)

The composition of claim 9, wherein the weight ratio of said first herbicide to florasulam is about 1:1.

### Claim 11 (depends on 9)

The composition of claim 9, wherein the herbicide is the methyl ester or TEA salt of the compound of formula (I).
