Abstract

Herbicidal injury caused by 6-trisubstituted phenyl)-4-amino-2-pyridinecarboxylates in wheat and barley is reduced with the use of low rates of cloquintocet.

Claims

1. A composition for protecting wheat and barley from the harmful effects of a 6-(trisubstituted phenyl)-4-amino-2-pyridine-carboxylate herbicide of the formula (I)

2. The composition of claim 1 in which the 6-(trisubstituted phenyl)-4-amino-2-pyridinecarboxylate herbicide is a 4-amino-3-chloro-6-(4-chloro-2-fluoro-3-methoxyphenyl)-2-pyridinecarboxylic acid derivative or a 4-amino-3-chloro-6-(2,4-dichloro-3-methoxy-phenyl)-2-pyridinecarboxylic acid derivative.

3. The composition of claim 1 in which the weight ratio of the 6-(trisubstituted phenyl)-4-amino-2-pyridinecarboxylate herbicide to cloquintocet acid is from 4:

1 to 32;

1.

4. The composition of claim 1 in which the weight ratio of the 6-(trisubstituted phenyl)-4-amino-2-pyridinecarboxylate herbicide to cloquintocet acid is from 8:

1 to 64;

1.

5. A method of protecting wheat and barley from the harmful effects of applying a 6-(trisubstituted phenyl)-4-amino-2-pyridinecarboxylate herbicide of the formula (I)

6. The method of claim 5 wherein the 6-(trisubstituted phenyl)-4-amino-2-pyridinecarboxylate herbicide is a 4-amino-3-chloro-6-(4-chloro-2-fluoro-3-methoxyphenyl)-2-pyridinecarboxylic acid derivative or a 4-amino-3-chloro-6-(2,4-dichloro-3-methoxy-phenyl)-2-pyridinecarboxylic acid derivative.

7. The method of claim 5 wherein the amount of cloquintocet acid applied is such that the weight ratio of 6-(trisubstituted aryl)-4-amino-2-pyridinecarboxylate herbicide to cloquintocet acid is from 2:

1 to 64;

1.

8. The method of claim 5 wherein the amount of cloquintocet acid applied is such that the weight ratio of 6-(trisubstituted aryl)-4-amino-2-pyridinecarboxylate herbicide to cloquintocet acid is from 4:

1 to 32;

1.

9. The method of claim 5 wherein the amount of cloquintocet acid applied is such that the weight ratio of 6-(trisubstituted aryl)-4-amino-2-pyridinecarboxylate herbicide to cloquintocet acid is from 8:

1 to 64;

1.
