Rotenone is a broad spectrum pesticide and insecticide and is also considered as a non-selective piscicide.
The action mechanism of the rotenone has been described below -
It interferes with the electron transport chain which occurs in mitochondria of the cells. Here the transfer of electrons from complex I to the ubiquinone is inhibited by the rotenone. As a result, ATP formation with the help of NADH is also inhibited. When electron transport fails, oxygen in the cell is reduced to oxygen radical which further damages DNA and other components present in the mitochondria.
