Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
71 words
A method for combatting insects comprising applying to said insects, or to an insect habitat, an insecticidal amount of cyclopropanecarboxylic acid ester of the formula ##STR11## wherein R is a cyclopropane moiety selected from the group consisting of ##STR12## and wherein R 1 is a 3-coumaranyl moiety of the formula ##STR13## wherein R 2 is selected from the group consisting of hydrogen, halogen, nitro, thiomethyl, alkyl, alkoxyl, sulfonylmethyl, phenyl and benzyl.
Claim 2
Independent Claim
71 words
A method for combatting insects comprising applying to said insects, or to an insect habitat, an insecticidal amount of cyclopropanecarboxylic acid ester of the formula ##STR11## wherein R is a cyclopropane moiety selected from the group consisting of ##STR12## and wherein R 1 is a 3-coumaranyl moiety of the formula ##STR13## wherein R 2 is selected from the group consisting of hydrogen, halogen, nitro, thiomethyl, alkyl, alkoxyl, sulfonylmethyl, phenyl and benzyl.
Claim 3
Dependent Claim
45 words
