Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 100 words
A method of combating insect or acarid pests at a locus which comprises applying to the locus a pesticidally effective amount of a cyanobenzyl cyclopropane carboxylate of the formula ##EQU2##wherein Hal represents a chlorine atom; R 1 and R 2 each represents an alkyl group of 1 to 6 carbon atoms; and X represents a phenyl group optionally substituted by one or more chlorine atoms, by one or more alkyl groups of 1 to 6 carbon atoms or by a phenoxy, tolyloxy, propargyloxy or benzyl group, or a composition of said carboxylate with at least one carrier or surface-active agent.
Claim 2
Independent Claim 100 words
A method of combating insect or acarid pests at a locus which comprises applying to the locus a pesticidally effective amount of a cyanobenzyl cyclopropane carboxylate of the formula ##EQU2##wherein Hal represents a chlorine atom; R 1 and R 2 each represents an alkyl group of 1 to 6 carbon atoms; and X represents a phenyl group optionally substituted by one or more chlorine atoms, by one or more alkyl groups of 1 to 6 carbon atoms or by a phenoxy, tolyloxy, propargyloxy or benzyl group, or a composition of said carboxylate with at least one carrier or surface-active agent.
Claim 3
Dependent Claim 44 words
A method as claimed in claim 1 wherein R 1 and R 2 each represents a methyl group and X represents a phenyl group optionally substituted by one or more chlorine atoms or methyl groups or by a phenoxy, tolyloxy, propargyloxy or benzyl group.
Claim 4
Dependent Claim 17 words
A method as claimed in claim 2 wherein the cyanobenzyl cyclopropane carboxylate is alpha-cyano-3-phenoxybenzyl 2,2-dichloro-3,3-dimethyl cyclopropane carboxylate.
Claim 5
Dependent Claim 17 words
A method as claimed in claim 2 wherein the cyanobenzyl cyclopropane carboxylate is alpha-cyano-3-tolyloxybenzyl 2,2-dichloro-3,3-dimethyl cyclopropane carboxylate.
Claim 6
Dependent Claim 31 words
An insecticidal or acaricidal composition comprising an insecticidally or acaricidally effective amount of a cyanobenzyl cyclopropane carboxylate as shown in claim 1 together with at least one carrier or surface-active agent.
