General description

Metolachlor ESA sodium salt is used for the control of broadleaf weeds and annual grasses in primarily corn, soybean, and sorghum. Active compounds of metolachlor pesticide may be converted by the target insects or plants or may be degraded in the environment to form the corresponding ethanesulfonic (ESA) acids, oxanillic (OA) acids, and other degradates. Metolachlor ESA sodium salt is one of the metabolites of metolachlor.
