    APPLICATIONS

    Biochemistry Acts on the nervous system of insects, disturbs the function of neurons by interaction with the sodium channel.  Mode of action Non-systemic insecticide with contact and stomach action, and repellent properties. Gives rapid knockdown and long residual activity.  Uses Control of a wide spectrum of insect pests, e.g. aphids, Colorado beetles, thrips, Lepidoptera larvae, Coleoptera larvae and adults, etc., in cereals, hops, ornamentals, potatoes, vegetables, cotton, and other crops. Provides good control of insect-borne plant viruses, at 2-5 g/ha. Also used for control of insect pests in public health. Formulation types CS; EC; EW; UL; WG; WP. 

     

    ANALYSIS

    Product analysis of pyrethroids reviewed by E. Papadopoulou-Mourkidou in Comp. Analyt. Profiles. By capillary glc with FID (CIPAC Handbook, 1992, E, 49-57). Residues determined by glc with ECD (AOAC Methods, 17th Ed., 998.01). Details available from Syngenta. 

     

    MAMMALIAN TOXICOLOGY

    Oral Acute oral LD50 for male rats 79, female rats 56.  Skin and eye Acute percutaneous LD50 for rats 632-696 mg/kg. Mild eye irritant; non-irritant to skin (rabbits). Not a skin sensitiser (guinea pigs).  Inhalation LC50 (4 h) for rats 0.06 mg/l air (total particulate).  NOEL (1 y) for dogs 0.5 mg/kg daily.  ADI 0.005 mg/kg.  Other Non-mutagenic in the Ames test.  Toxicity class WHO (a.i.) II; EPA (formulation) II ('Karate', 'Warrior')  EC classification T+; R26| T; R25| Xn; R21| N; R50, R53 

     

    ECOTOXICOLOGY

    Birds Acute oral LD50 for mallard ducks >3950 mg/kg. Dietary LC50 for quail >5300 mg/kg. No accumulation of residues in eggs or tissues.  Fish LC50 (96 h) for bluegill sunfish 0.21, rainbow trout 0.36μg/l.  Daphnia EC50 (48 h) 0.36 μg/l.  Algae ErC50 (96 h) for Selenastrum capricornutum >1000μg/l.  Other aquatic spp. Intrinsic toxicity to aquatic organisms is greatly reduced by rapid loss from the water by adsorption and degradation.  Bees LD50 (oral) 38 ng/bee; (contact) 909 ng/bee.  Worms LC50 for Eisenia foetida >1000 mg/kg soil.  Other beneficial spp. Toxic to some non-target arthropods. Effects under field conditions reduced, with rapid recovery. 

     

    ENVIRONMENTAL FATE

    Animals In rats, following oral administration, rapidly eliminated in urine and faeces. The ester group is hydrolysed, both moieties forming polar conjugates.  Plants For details of metabolism of lambda-cyhalothrin in cotton and soya bean leaves, see D. A. French & J. P. Leahey, Proc. Br. Crop Prot. Conf. - Pests Dis., 1990, 3, 1029-1034.  Soil/Environment Rapidly degraded in soil; DT50 for microbial degradation 23-82 d, for field soil 6-40 d. Strongly adsorbed to soil and sediment organic matter, Koc 330 000. Negligible potential for leaching of lambda-cyhalothrin and its degradation products through soil. Rapid dissipation from water in aquatic systems. DT50 for dissipation from surface waters in lab. water-sediment systems 5-11 h; in a microcosm DT50 <3 h. Rapid and extensive degradation of parent compound in aquatic systems; DT50 for degradation in lab. water-sediment systems 7-15 d; in a microcosm DT50 <3 h, DT90 <3 d.
