If this chemical gets into the eyes, remove any
contact lenses at once and irrigate immediately for at least
15 minutes, occasionally lifting upper and lower lids. Seek
medical attention immediately. If this chemical contacts the
skin, remove contaminated clothing and wash immediately
with soap and water. Seek Medical attention immediately.
If this chemical has been inhaled, remove from exposure,
begin rescue breathing (using universal precautions) if
breathing has stopped, and CPR if heart action has stopped.
Transfer promptly to a medical facility. When this chemical
has been swallowed, get medical attention. Give large quantities of water and induce vomiting. Do not make an
unconscious person vomit. | [Shipping]

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. |
Questions And Answer | Back Directory | [Description]
Cyhalothrin is a broad-spectrum pesticide and acaricide that is used to control a wide range of pests in a variety of applications. It belongs to the pyrethroid, a class of synthetic insecticides which has the similar structure and insecticidal activity of the naturally occurring insecticide pyrethrum, derived from the flowers of chrysanthemums. It is commercially used for controlling insects on non-food crops, greenhouses, hospitals, and crops, such as cotton, cereals, hops, ornamentals, potatoes, vegetables, etc. and it targets various kinds of pests, including aphids, Colorado beetles and butterfly larvae. Besides, it is effective to used in public health applications to control insects identified as potential disease vectors, such as cockroaches, mosquitoes, ticks, and flies.
Registered with the EPA in 1988, Cyhalothrin is often preferred as an active ingredient in insecticides because it is proved to be mostly insoluble in water, which is an unlikely water contaminant. It is also nonvolatile, which makes it remain effective for extended periods of time.
