Chemical Detoxication of Atrazine by Dexon1

The nonphytotoxic analogs of atrazine (2-chloro-4-ethylamino, 6 isopropylamino-s triazine) are hydroxyatrazine and protonated hydroxyatrazine. Distinctive infrared bands of these compounds appear at 1620, 1680, and 1740 cm-1, respectively. By monitoring these distinctive bands of the compounds, it has been demonstrated that in a combination of atrazine and dexon (p-[dimethylamino] benzenediazo sodium sulphonate) there is a time-dependent chemical change of some atrazine to protonated hydroxyatrazine indicating a reduction in phytotoxicity of the s-triazine. A part of dexon-atrazine antagonism—the reduction of atrazine toxicity to certain plants in the presence of dexon—is due to chemical reaction.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
