General description
Metolachlor is used for the control of broadleaf weeds and annual grasses primarily in 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 oxanillic (OA) acids. Metolachlor OA is one of the metabolite of metolachlor.
