The toxicity of diquat

Abstract

The toxicity of diquat. The acute toxicity of diquat has been assessed in several species. The oral LD50 ranged from about 30 mg/kg in cattle to 231 mg/kg in the rat. Large doses of diquat gave rise to symptoms indicative of an action on the central nervous system, but smaller doses did not suggest an obvious mode of action to account for the deaths, which were some- times delayed for up to 14 days.
