Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
47 words
A method for the systemic control of ectoparasites which attack warm-blooded animals comprising orally or parenterally administering to the animals a systemically effective amount against the parasites of a cyclopropanecarboxylic acid of the formula: ##STR9## wherein R is 2,2-dichlorovinyl- or 2-methyl-propenyl- and R' is hydrogen or cyano.
Claim 2
Independent Claim
47 words
A method for the systemic control of ectoparasites which attack warm-blooded animals comprising orally or parenterally administering to the animals a systemically effective amount against the parasites of a cyclopropanecarboxylic acid of the formula: ##STR9## wherein R is 2,2-dichlorovinyl- or 2-methyl-propenyl- and R' is hydrogen or cyano.
Claim 3
Dependent Claim
38 words
A method according to claim 1 for the control of ixodid ticks, wherein the compound cyclopropanecarboxylic acid, 3-(2,2-dichlorovinyl)-2,2-dimethyl-m-phenoxybenzyl ester, cis- trans isomer is administered orally in amounts of 0.01 mg to 600 mg per kilogram animal body weight.
Claim 4
Dependent Claim
38 words
A method according to claim 1 for the control of ixodid ticks wherein the compound cyclopropanecarboxylic acid, 2,2-dimethyl-3-(2-methyl-propenyl)-m-phenoxybenzyl ester cis and trans isomersis administered orally in amounts of 0.01 mg to 600 mg per kilogram animal body weight.
Claim 5
Dependent Claim
25 words
A method according to claim 2, wherein the compound is administered orally in amounts of 100 mg to 400 mg per kilogram animal body weight.
Claim 6
Dependent Claim
25 words
A method according to claim 3, wherein the compound is administered orally in amounts of 100 mg to 400 mg per kilogram animal body weight.
Claim 7
Dependent Claim
29 words
A method according to claim 1 for the control of ixodid ticks, wherein the compound is introduced into the animal's circulatory system by a subcutaneous, intramuscular or intraperitoneal injection.
Claim 8
Dependent Claim
35 words
A method according to claim 6, wherein the compound cyclopropanecarboxylic acid, 3-(2,2-dichlorovinyl)-2,2-dimethyl-m-phenoxybenzyl ester cis-trans isomers is introduced into the animals circulatory system in amounts of 0.01 mg to 600 mg per kilogram animal body weight.
Claim 9
Dependent Claim
35 words
A method according to claim 6, wherein the compound cyclopropanecarboxylic acid, 2,2-dimethyl-3-(2-methylpropenyl)-m-phenoxybenzyl ester, cis-trans isomers is introduced into the animals circulatory system in amounts of 0.01 mg to 600 mg per kilogram animal body weight.
Claim 10
Dependent Claim
26 words
A method according to claim 7, wherein said compound is introduced into the animals circulatory system in amounts of 100 mg per kilogram animal body weight.
Claim 11
Dependent Claim
29 words
A method according to claim 8, wherein said compound is introduced into the animal's circulatory system in amounts of 100 mg to 400 mg per kilogram animal body weight.
Claim 12
Dependent Claim
33 words
A method according to claim 1 for the control of ixodid ticks wherein the compound is incorporated in a nutritionally balanced animal feed in amounts of 0.01% to 2.5% by weight of feed.
Claim 13
Dependent Claim
27 words

Claim 14
Dependent Claim
27 words
A method according to claim 11, wherein the compound cyclopropanecarboxylic acid, 2,2-dimethyl-3-(2-methyl-propenyl)-m-phenoxybenzyl ester, cis-trans isomere is incorporated in amounts of 0.01% to 1.0% by weight of feed.
Claim 15
Dependent Claim
39 words
A method according to claim 1 for the control of ixodid ticks wherein the compound cyclopropanecarboxylic acid, 3-(2-2-dichlorovinyl)-2,2-dimethyl-α-cyano-m-phenoxybenzyl ester, cis and trans isomers is administered orally in amounts of 0.01 mg to 600 mg per kilogram animal body weight.
Claim 16
Dependent Claim
40 words
A method according to claim 1 for the control of ixodid ticks wherein the compound cyclopropane carboxylic acid, 2,2-dimethyl-3-(2-methyl-propenyl)-α-cyano-m-phenoxybenzyl ester cis and trans isomers is administered orally in amounts of 0.01 mg to 600 mg per kilogram animal body weight.
