Claims10
A composition for protecting wheat and barley from injury caused by a 6-(trisubstituted phenyl)-4-amino-2-pyridine-carboxylate herbicide of the formula (I)
- wherein hal represents F, Cl or Br, and R represents methyl or ethyl,
- and its agriculturally acceptable salt, ester and amide derivatives which comprises the 6-(trisubstituted phenyl)-4-amino-2-pyridinecarboxylate herbicide and cloquintocet acid, in a weight ratio of 6-(trisubstituted aryl)-4-amino-2-pyridinecarboxylate herbicide to cloquintocet acid of from 2:1 to 64:1;
- wherein herbicidal injury caused by 6-(trisubstituted phenyl)-4-amino-2-pyridine-carboxylate is reduced by cloquintocet acid.
A method of protecting wheat and barley from injury caused by applying a 6-(trisubstituted phenyl)-4-amino-2-pyridinecarboxylate herbicide of the formula (I)
- wherein hal represents F, Cl or Br, and R represents methyl or ethyl,
- and its agriculturally acceptable salt, ester and amide derivatives which comprises contacting the wheat and barley with cloquintocet acid, or applying cloquintocet acid to the area under cultivation, in an amount such that the weight ratio of 6-(trisubstituted aryl)-4-amino-2-pyridinecarboxylate herbicide to cloquintocet acid is from 2:1 to 64:1;
- wherein herbicidal injury caused by 6-(trisubstituted phenyl)-4-amino-2-pyridine-carboxylate is reduced by cloquintocet acid.
