APPLICATIONS
Mode of action: Non-systemic insecticide with contact and stomach action, having a slight repellent effect.


Formulation types: DP; EC; UL; WG; WP; Fumigant; Aerosol.


Compatibility: Mixing with calcium nitrate is not recommended.

MAMMALIAN TOXICOLOGY
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

ECOTOXICOLOGY
Birds: Typical oral LD50 values 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 ug/l; (48 h) for rainbow trout 5.4, bluegill sunfish 1.8 ug/l.
Daphnia: LC50 (48 h) 0.6 ug/l.
Bees: Toxic to bees. LD50 (24 h) (oral) 0.098 ug/bee; (topical) 0.029 ug/bee.

 

ENVIRONMENTAL FATE
EHC: Permethrin is not likely to be a hazard to the environment when used as recommended.
Animals: In mammals, there is hydrolysis of the ester bond, hydroxylation, and elimination as the glucoside conjugate.
Soil/Environment: In soil and water, degradation is rapid. DT50 in soil <38 d (pH 4.2-7.7, o.m. 1.3-51.3%).
