Abstract
An enhancer composition for agricultural chemicals which can enhance the effectiveness of an agricultural chemical without causing any phytotoxicity to various crops, which comprises at least one nitrogen-containing compound selected from the group consisting of a tertiary amine, a tertiary amine salt and a quaternary ammonium salt and a chelating agent, wherein the content of the chelating agent ranges from 0.01 to 30 mol per mol of the nitrogen-containing compound.
