Abstract
Abstract A new method of controlling pests harmful to domestic animals and certain novel pesticidal compositions are described. Compounds for use in the method have the formula <IMAGE> in which n is 0 to 5, R is halo, alkyl, trihaloalkyl, cyano alkoxy or alkoxycarbonyl, R1 and R2 are each hydrogen, alkyl alkenyl, alkynyl, acyl, or hydrocarbyloxycarbonyl and R3 and R4 are each hydrogen or alkyl; or an acid addition. The method is of particular value for controlling ectoparasites which attack cattle and pigs. Certain of the compounds are novel.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
75 words
The method for combating an infestation of insect or acarid ectoparasites harmful to domestic animals which comprises contacting the ectoparasite with a concentration of from 0.001 to 1.0 percent by weight of a compound of the formula ##STR22## in which R is selected from the group consisting of halo, alkyl of 1 to 4 carbon atoms, inclusive; trifluoromethyl; cyano; alkoxy of 1 to 4 carbon atoms, inclusive; methoxycarbonyl, and ethoxycarbonyl; and acid addition salts thereof.
Claim 2
Independent Claim
75 words
The method for combating an infestation of insect or acarid ectoparasites harmful to domestic animals which comprises contacting the ectoparasite with a concentration of from 0.001 to 1.0 percent by weight of a compound of the formula ##STR22## in which R is selected from the group consisting of halo, alkyl of 1 to 4 carbon atoms, inclusive; trifluoromethyl; cyano; alkoxy of 1 to 4 carbon atoms, inclusive; methoxycarbonyl, and ethoxycarbonyl; and acid addition salts thereof.
Claim 3
Dependent Claim
31 words
The method for combating an infestation of insect or acarid ectoparasites harmful to domestic animals according to claim 1 wherein "R" substituents are halogen or alkyl and acid addition salts thereof.
Claim 4
Dependent Claim
17 words
The method according to claim 2 for combating ectoparasites which comprises externally applying the compound to livestock.
Claim 5
Dependent Claim
22 words
