Reviews FAO/WHO 86, 88 (see part 2 of the Bibliography). See also A. J. Gray & D. M. Soderlund, Chapt. 5 in "Insecticides". IARC ref. 53 class3 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 >13800 mg/m3). NOEL In 2 y feeding trials, rats receiving 100 mg/kg diet showed no ill-effects. ADI (JMPR) 0.05 mg/kg b.w. (for tech., with cis/transratios 25:75 to 40:60) [1999]. Water GV 20 mg/l (based on ADI). Other No mutagenic, teratogenic, or carcinogenic activity. Toxicity classWHO (a.i.)

Uses:

Non-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/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.
