Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
131 words
A method of controlling insect or acarid pests which comprises contacting the locus of said pests with an insecticidally or acaricidally effective amount of an aryl-substituted thiazole having the following structural formula: ##STR4## wherein R is selected from the group consisting of phenyl, alkylphenyl having 7 to 14 carbon atoms, aminophenyl, alkaminophenyl having 7 to 14 carbon atoms, halophenyl, and hydroxyphenyl; R 1 is selected from the group consisting of hydrogen, alkyl having 1 to 5 carbon atoms, phenyl, biphenylyl, aminophenyl, alkaminophenyl having 7 to 14 carbon atoms, alkylphenyl having 7 to 14 carbon atoms, and halophenyl; and R 2 is selected from the group consisting of hydrogen, alkyl having 1 to 5 carbon atoms, phenyl, halophenyl, and nitro; provided that two of R, R 1 and R 2 are aromatic.
Claim 2
Independent Claim
