A method for enhancing an efficacy of an agricultural chemical which comprises incorporating a specific quaternary ammonium enhancer into a diluted solution of the agricultural chemical.

Agricultural chemical composition

To provide processes suitable for industrial production by which high-purity N-(long-chain acyl)amino acid and salt thereof can be prepared from inexpensive raw materials. An alkyl ester of a fatty acid (2) is reacted with an aminonitrile (3) in the presence of a basic catalyst to form an amidonitrile (1), the amidonitrile (1) is hydrolyzed into an N-(long-chain acyl)amino acid salt (4) in the presence of a basic substance, the pH of the resulting aqueous solution is adjusted to a pH from 1 to 5 with a mineral acid to form an N-(long-chain acyl)amino acid (5), and this amino acid is recovered. ##STR1## wherein R.sup.1 CO-- represents a fatty acid residue having 8 to 22 carbon atoms; R.sup.2 represents a hydrogen atom or an alkyl group having 1 to 3 carbon atoms; R.sup.3 represents an alkylene group having 1 to 5 carbon atoms; R.sup.4 represents an alkyl group having 1 to 4 carbon atoms; and M represents a monovalent cation.
