Use

The acute toxicity of diquat dibromide ismoderate to high in most species. In domes-tic animals, its toxicity is greater than thatin small laboratory animals. The oral LD50value in cows, dogs, rabbits, and mice is30, 187, 188, and 233 mg/kg, respectively.The symptoms of acute toxicity are somnolence, lethargy, pupillary dilation, and respiratory distress. Prolonged exposure to thiscompound produced cataracts in experimental animals. Intratracheal administration ofdiquat dibromide in rats showed toxic effectsin the lung and caused lung damage (Manabeand Ogata 1986). But when administered byoral or intravenous routes, there was no toxiceffect on the lung.
