<p>Novel substituted 1-pyridyloxyphenyl-3-benzoylparabanic acids of the formula <IMAGE> wherein R1 is hydrogen, halogen or C1-C4alkyl, R2 and R3, each independently of the other, are halogen or C1-C4alkyl, R4 is hydrogen or halogen, R5 is halogen or C1-C4alkyl which is halogenated by fluorine and/or chlorine, and n is 0, 1 or 2, and the pyridyloxy group is linked to the phenyl group in the 3- or 4-position. A process for the preparation of these compounds and compositions containing them for use in pest control, especially for controlling insects which attack plants and animals, are disclosed. The novel compounds are particularly effective against plant-destructive insects, especially when employed as ovicides.</p> |
