Compliance with the tolerance levels specified below is to be determined by measuring only permethrin [(3
Permethrin was first registered and tolerances established in the United States in 1979
The International Union of Pure and Applied Chemistry (IUPAC) name for permethrin is 3-phenoxybenzyl (1RS,3RS;1RS,3SR)-3- (2,2-dichlorovinyl)-2,2-dimethyl-cyclopropanecarboxylate and the Chemical Abstracts
Tolerances are established for residues of permethrin, including its metabolites and

Permethrin exhibited no mutagenic potential in genetic toxicity studies(in vitro and in vivo)
Compliance with the tolerance levels specified below is to be determined by measuring only More than 425 pesticide and veterinary drug residue tolerances in major export markets for hay, feed, grains, oilseeds, poultry, eggs, meat and dair y; The database does not include processed food products
Permethrin is a commonly used acaricide for tick control on domestic animals and in residential environments, while fipronil use is restricted to on-animal treatment
Ten groups of 90 Aedes aegypti females were used in the study, and permethrin exposure resulted in elevated levels of α-esterase (Flores et al

EPA has reviewed and made the requisite safety finding for the permethrin tolerances included in this notice

sanguineus permethrin resistance and fipronil tolerance in the United States and potential causes of resistance development and recommendations on future brown dog tick control management plans are discussed

Of 19 populations tested, 12 were found resistant to temephos while 7 populations demonstrated tolerance
