<p>Substituted thiophenes of the following formula, some of which are new compounds, are useful in controlling certain arthropods, particularly mites and insects: where X is alkyl, halogen, nitro, haloalkyl, alkoxy, alkylthio or aryl; a is 0, 1 or 2; Y is hydrogen, halogen, nitro, aryl, arylthio or arylsulfono; and Z is hydrogen, or aryl. E.g., 2,3,5-triphenylthiophene is highly effective in controlling mites.</p> |
