Abstract
The invention relates to certain naphthoquinone derivatives, some of which are novel, of the general formula I ##STR1## in which R represents a hydrogen atom or a hydroxyl or an ethanoyloxy group; methods for their preparation; compositions containing such compounds and their use as pesticides, such as fungicides and, especially, insecticides and acaricides.
