N-Tetrafluorophenyl-N'-difluorobenzoylureas, pesticides containing them, and processes for their preparation

摘要

Substituted N-tetrafluorophenyl-N'-2,6-dibenzoylureas of the formula <IMAGE> processes for the preparation of these compounds, and compositions containing them for use in pest control, especially for controlling insects which infest plants and animals. The new compounds are also active in inhibiting feeding by insects which damage plants, and possess favourable ovicidal and ovolarvicidal properties.
