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.
