Abstract
A liquid enhancer composition for amino acid series herbicides comprising specific tertiary amine and a derivative thereof, at least one oxalic acid or a salt thereof selected from the group consisting of oxalic acid, potassium oxalate, alkanolamine salts of oxalic acid, and lower alkylamine salts of oxalic acid, wherein the ratio of oxalic acid or the salt thereof is 0.1 to 10 times mole per mole of the nitrogen-containing compound. The enhancer composition of the present invention has an excellent stability with lapse of time to a change in temperatures and can markedly enhance the medicinal efficacy of an amino acid series herbicide even when the composition is used in a liquid form in combination with the herbicide.
