PHYSICAL CHEMISTRY Composition: Tech. grade alpha-cypermethrin is >90% pure m/m, typically >95%. Mol. wt.: 416.3; M.f.: C22H19Cl2NO3; Form: Colourless crystals; (tech. is a white to pale powder, with a weak aromatic odour); M.p.: 78-81 ºC; B.p.: 200 ºC/9.3 Pa; V.p.: 2.3x10-2 mPa (20 ºC); KOW: logP = 6.94 (pH 7); Henry: 6.9x10-2 Pa m3 mol-1 (calc.) S.g./density: 1.28 (22 ºC); Solubility: In water c. 0.01 mg/l (25 ºC). In acetone 620, dichloromethane 550, cyclohexanone 515, ethyl acetate 440, chlorobenzene 420, acetophenone 390, o-xylene 350, hexane 7 (all in g/l, 25 ºC). In maize oil 19-20, ethylene glycol 80 ºC (closed cup). APPLICATIONS Mode of action: Non-systemic insecticide with contact and stomach action. Acts on the central and peripheral nervous system in very low doses. Uses: Control of a wide range of chewing and sucking insects (particularly Lepidoptera, Coleoptera, and Hemiptera) in fruit (including citrus), vegetables, vines, cereals, maize, beet, oilseed rape, potatoes, cotton, rice, soya beans, forestry, and other crops. Control of cockroaches, mosquitoes, flies, and other insect pests in public health; and flies in animal houses. Also used as an animal ectoparasiticide. Formulation types: EC; SC; TB; UL; WP. Compatibility: Compatible with most organophosphorus insecticides. MAMMALIAN TOXICOLOGY Oral: Acute oral LD50 for rats 79-400 mg/kg (in corn oil, value depending on concentration), 474 mg tech./kg. Skin and eye: Acute percutaneous LD50 for rats and rabbits >2000 mg tech./kg; minimal irritant to the eyes of rabbits. Inhalation: LC50 (4 h) for rats 0.32 mg/l air. NOEL: In 90 d feeding trials, rats receiving 60 mg/kg diet showed no ill-effects. ADI: 0.02 mg/kg b.w. Other: Non-mutagenic. Toxicity class: WHO (a.i.) II; EPA (formulation) II ECOTOXICOLOGY Birds: LD50 for quail and mallard ducks >10 000 mg/kg. Fish: LC50 (96 h) for rainbow trout 0.0028 mg/l; due to rapid loss from water, no toxic effect to fish is observed under field conditions. Daphnia: LC50 (48 h) 0.1-0.3 g/l. Bees: Toxic to bees. LD50 (24 h) 0.059 g/bee. No toxic effect under field conditions. Worms: LD50 (14 d) for earthworms >100 mg/kg artificial soil. ENVIRONMENTAL FATE EHC: EHC 142 notes that, although highly toxic to fish, this is not realised under field conditions where rapid loss from water allows recovery of affected populations. Animals: See cypermethrin. Soil/Environment: Undergoes degradation in soil, DT50 c. 13 w in loamy soil.
