Use of tetramic acid derivatives for controlling pests by drip application onto soil

摘要

Tetramic acid derivatives (I) are used to control animal pests by drenching, drip application or soil injection. Tetramic acid derivatives of formula (I) are used to control animal pests by drenching, drip application or soil injection.
