Toxicity       
Oral: 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 LD50 is 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 >13 800 mg/m3).
NOEL: In 2 y feeding trials, rats receiving 100 mg/kg diet showed no ill-effects.
ADI: 0.05 mg/kg b.w. (for tech., with cis/trans ratios 25:75 to 40:60)
Water GV: 20 ug/l (based on ADI).
Other: No mutagenic, teratogenic, or carcinogenic activity.
Toxicity class: WHO (a.i.) II; EPA (formulation) II ('Ambush'); III ('Outflank')
EC hazard: Xn; R22
Application 
Permethrin is 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/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.
