Applicationsnon-systemic insecticide with contact and stomach action, having a slight repellent effect.A contact insecticide effective against a broad range of pests. It controls leaf- and fruit-eating lepidoptera and coleoptera in cotton, at 100-150 g a.I./ha, in fruit, at 25-50 g/ha, in tobacco, vines and other crops, at 50-200 g/ha, and in vegetables, at 40-70 g/ha. It has good residual activity on treated plants. It is effective against a wide range of animal ectoparasites, provides >60 d residual control of biting flies in animal housing, at 200 mg a.I. (as ec)/m2 wall or 30 mg a.I. (as wp)/m2 wall, and is effective as a wool preservative, at 200 mg/kg wool. It provides >120 d control of blattodea, diptera, hymenoptera and other crawling insects, at 100 mg a.I. (as wp)/m2, also flying insects.
Toxicologyoral oral ld50 values of permethrin depend on such factors as: carrier, cis/trans ratio of the sample, the test species, its sex, age and degree of fasting; values reported sometimes differ markedly. Values for a cis/trans ratio of c. 40:60 are: for rats 430-4000, mice 540-2690 mg/kg; with a 20:80 ratio, the ld50is c. 6000 mg/kg.Skin and eye acute percutaneous ld50 for rats >2500, rabbits >2000 mg/kg. Mild eye and skin irritant (rabbits). Moderate skin sensitiser.Inhalation lc50 (3 h) for mice and rats >685 mg/m3 air; (separate study gives >13800 mg/m3). Birds typical oral ld50values for a cis/trans ratio of c. 40:60 are: for chickens >3000, mallard ducks >9800, japanese quail >13 500 mg/kg.Fish lc50 (96 h) for rainbow trout 2.5 mg/l; (48 h) for rainbow trout 5.4, bluegill sunfish 1.8 mg/l.Daphnia lc50 (48 h) 0.6mg/l.Bees toxic to bees. Ld50(24 h) (oral) 0.098mg/bee; (topical) 0.029mg/bee.
