ToxicologyOral:Acute oral LD50 for albino rats 6210, guinea pigs 2025 mg/kg. Percutaneous:Acute percutaneous LD50 for rats and albino rabbits >2000 mg/kg; a slight irritant to the eyes and skin of rabbits. Inhalation:LC50 for rats >2.18 mg/l air. There was no adverse effect when albino rats were exposed to an aerosol (66% vol. mixture of tech. product and acetone). Phytotoxicity:A large number of crops are susceptible, including cereals, maize, carrots, flax, onions,
