Abstract
Novel substituted N-(2-pyridyloxyphenyl)-N'-benzoylureas of the formula ##STR1## wherein R.sub.1, R.sub.2, R.sub.3 and R.sub.4 independently of one another are each hydrogen, methyl or halogen, PA1 R.sub.5 is the radical --CHF.sub.2, or a C.sub.2 -C.sub.10 -alkyl group which is uniformly or nonuniformly substituted by 1 to 21 halogen atoms, and PA1 R.sub.6 is halogen, processes and starting products for producing these compounds, as well as compositions containing these, for use in combating pests, particularly for combating insects which infest plants and animals. The novel compounds have a specially high ovolarvicidal and ovicidal action against insects that damage plants.
