This invention provides an agricultural chemical composition comprising an enhancer
for agricultural chemicals, which is excellent in stability even when compounded
at high concentration, and exerts an excellent effect-enhancing action on agricultural
chemicals. A specific amine oxide having a C6-30 alkyl or alkenyl group
or an alkylphenyl group having a C6-17 alkyl group, and an amide alkyl
group or oxyalkylene group is used as the enhancer for agricultural chemicals.
