Description

Dicamba is an organochloride derivative of benzoic acid. It is used as a non-specific herbicide that is usually used on non-crop  plants. Dicamba is moderately toxic to humans, and both persistent and mobile in soils. The EURL (European Union Reference Laboratory) tested dicamba in an analysis of acidic pesticides. Primesep 100 and Obelisc R were used to separate dicamba with unique separation. Method is LC/MS compatible
