Bifenthrin APPLICATIONS
Mode of action Contact and stomach action. Uses Effective against a broad range of foliar pests, including Coleoptera, Diptera, Heteroptera, Homoptera, Lepidoptera and Orthoptera; it also controls some species of Acarina. Crops include cereals, citrus, cotton, fruit, grapes, ornamentals and vegetables. Rates range from 5 g a.i./ha against Aphididae in cereals to 45 g/ha against Aphididae and Lepidoptera in top fruit. Formulation types EC; GR. SC; UL; WP. Compatibility Not compatible with alkaline materials. Selected tradenames: 'Talstar' (FMC)

MAMMALIAN TOXICOLOGY
Reviews FAO/WHO 65, 67 (see part 2 of the Bibliography). 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 (JMPR) 0.02 mg/kg [1992]. Toxicity class WHO (a.i.) II; EPA (formulation) II

ECOTOXICOLOGY
Birds 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. Bees LD50 (oral) 0.1 mg/bee; (contact) 0.01462 mg/bee.
