Abstract
Novel substituted 1,3-benzodithiol-2-N,N-dialkyliminium salts of the formula ##STR1## wherein R.sub.1 and R.sub.2 independently of one another are each hydrogen, C.sub.1 -C.sub.5 -alkyl, C.sub.3 -C.sub.6 -cycloalkyl, C.sub.3 -alkenyl, C.sub.3 -C.sub.5 -alkynyl or the radical --(CH.sub.2).sub.n --OR, in which R is C.sub.1 -C.sub.4 -alkyl, and n is the number 2 or 3; R.sub.3 and R.sub.4 independently of one another are each C.sub.1 -C.sub.4 -alkyl, or together they are the radical --(CH.sub.2).sub.4 -- or --(CH.sub.2).sub.5 --; and X.sup..crclbar. is a molar equivalent of an anion of an inorganic or organic acid; processes for producing these compounds, as well as compositions containing them, and their use for combating pests, particularly for combating members of the order Acarina which infest plants and animals.
