white fly. Resmethrin is a synthetic Type I pyrethroid
insecticide registered for control of insects in residential,
commercial, and industrial settings, and in animal living
areas. It is also registered for use in food handling estab-
lishments and as a restricted use pesticide when used in
ULV spray to control adult mosquitoes in the interest of
public health . A United States Restricted Use Pesticide
(RUP) when formulated for use in mosquito abatement and
pest control treatments at nonagricultural sites. Restricted
due to extreme fish toxicity. | [First aid]

UN3352 Pyrethroid pesticide, liquid toxic,
Hazard Class: 6.1; Labels: 6.1-Poisonous materials.
UN3349 Pyrethroid pesticide, solid toxic, Hazard Class:
6.1; Labels: 6.1-Poisonous material | [Incompatibilities]
Decomposed by air, light, alkaline
media, and temperatures .175℃. May react violently with
strong oxidizers, bromine, 90% hydrogen peroxide, phos-
phorus trichloride, silver powders or dust. Incompatible
with silver compounds. Mixture with some silver
compounds forms explosive salts of silver oxalate. | [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 . Bury in noncrop
land away from water. It would be better to mix the prod-
uct with lime. Incineration would be an effective disposal
procedure where permitted. If an efficient incinerator is not
available, the product should be mixed with large amount
of combustible material. Recommendable methods:
Hydrolysis, landfill, incineration, and open burning. Not
recommendable method: Discharge to sewer. Mix with saw-
dust and burn at a remote place . |
