Oral: Acute oral LD50 for rats 54.5 mg/kg.
Skin and eye: Acute percutaneous LD50 for rabbits >2000 mg/kg. Non-irritant to skin; virtually non-irritating to eyes (rabbits). No skin sensitisation (guinea pigs).
NOEL: (1 y) for dogs 1.5 mg/kg daily. Non-teratogenic in rats (2 mg/kg daily) and rabbits (8 mg/kg daily).
ADI: 0.02 mg/kg.
Toxicity class: WHO (a.i.) II; EPA (formulation) IIECOTOXICOLOGYBirds: Acute oral LD50 for bobwhite quail 1800, mallard ducks 2150 mg/kg. Dietary LC50(8 d) for bobwhite quail 4450, mallard ducks 1280 mg/kg diet.
Fish: LC50 (96 h) for bluegill sunfish 0.00035, rainbow trout 0.00015 mg/l.
Daphnia: LC50 (48 h) 0.00016 mg/l. Low solubility in water and high affinity for soil contribute to produce little impact in aquatic systems under field conditions.
