For the first time the electrochemical degradation of the pesticide dimethenamid‐P was studied. Its direct electrochemical degradation, using potential cycling at a gold electrode, was performed by cyclic voltammetry and HPLC analysis of electrolyte after 72 h showed 56.8 % of degradation. HPLC‐MS indicates the formation of degradation products through the elimination of chlorine atom and CN bond cleavage. By indirect electrolysis using DSA Ti/PtOx and DSA Ti/RuO 2 electrodes during 30 minutes 87.2 % and 88.3 % of dimethenamid‐P was degradated, respectively. The high percentage of degradation of dimethenamid‐P was achieved with non time consuming, simple and cheap electrochemical processes.
