Potential Exposure
Pyrethroid insecticide and acaridide used to control a variety of pests in many crops. Also used in structural pest situations. A United States Environmental Protection Agency Restricted Use Pesticide (RUP). Only cyhalothrin is banned for use in EU; not the lamda-isomer (CAS 68085-85-8).
Metabolic pathway
The solution and solid-phase photodecomposition of cyhalothrin involves E/Z and cis/trans isomerization reactions and frees radical processes leading to decarboxylation, ester cleavage, proton abstraction, oxygen scavenging, and reactions with solvent- generated radicals. The major degradation products are decarboxylated analogs which are also isomerized at the cyclopropyl and vinyl groups. In vitro incubation of 14C-cyhalothrin with honey bee mid-guts yields the principal metabolite identified as 4-hydroxy-3-phenoxybenzyl alcohol with a small amount of 3-phenoxybenzoic acid. In vivo metabolism with honey bees shows the major metabolites 4'-hydroxy-and 2'-hydroxy-3-phenoxybenzyl alcohols and 4'-hydroxy-3-phenoxybenzoic acid. Prochloraz delays the metabolism, detoxication, and excretion of cyhalothrin by inhibition of microsomal oxidation, effectively enhancing the toxicity to the honey bee.

UN3082 Environmentally hazardous substances, liquid, n.o.s., Hazard class: 9; Labels: 9-Miscellaneous hazardous material, Technical Name Required.br UN3077 Environmentally hazardous substances, solid, n.o.s., Hazard class: 9; Labels: 9-Miscellaneous hazardous material, Technical Name Required.
Incompatibilities
May react violently with strong oxidi- zers, bromine, 90% hydrogen peroxide, phosphorus trichloride, silver powders, or dust. Incompatible with silver compounds. Mixture with some silver compounds forms explosive salts of silver oxalate. Hydrolyzed by water
Waste Disposal
Incineration would be an effective disposal procedure where permitted. If an efficient incinerator is not available, the product should be mixed with large amounts of combustible material and contact with the smoke should be avoided. In accordance with 40CFR165, follow recommendations for the disposal of pesticides and pesticide containers.
