Abstract
Acaricidal 1-arylfurazanyl-3-(2-alkyl-4-halogenoalkoxyphenyl)-(thio)ureas of the formula ##STR1## in which Q stands for oxygen or sulphur, R.sup.1 stands for hydrogen, halogen, alkyl, halogenoalkyl, alkoxy, halogenoalkoxy, alkylthio or halogenoalkylthio, and R.sup.2 stands for hydrogen, halogen, alkyl or alkoxy, or R.sup.1 and R.sup.2 together stand for alkylenedioxy which is optionally substituted by halogen, R.sup.3 stands for alkyl and R.sup.4 stands for alkyl which is substituted by fluorine and optionally in addition by chlorine and/or bromine. The corresponding isocyanates of the formula ##STR2## are also new.
