The compounds of the formula:
wherein R represents phenyl substituted in at least the 2- position by fluorine, chlorine, bromine or iodine, R2 represents a group R3, -OR3, -SR3 or -NR3R4 where R3 represents hydrogen, alkyl of 1 to 6 carbon atoms, cycloalkyl of 3 to 7 carbon atoms, alkenyl of 2 to 6 carbon atoms, cycloalkenyl of 3 to 7 carbon atoms, alkynyl of 2 to 6 carbon atoms, phenyl, phenylalkyl of 7 to 10 carbon atoms or naphthyl, each of which may be unsubstituted or substituted by one or more halogen atoms, alkyl or alkoxy or alkylthio groups of 1 to 6 carbon atoms, nitro groups, cyano groups or mercapto groups, R4 represents a group as defined for R3 but not necessarily identical thereto, and A and B, together with the carbon atoms to which they are attached, form a 3,6-disubstituted pyridazine, a 3,6-disubstituted dihydropyridazine, a 2,5-disubstituted pyrimidine, a 1,2,4-oxadiazole, a 1,2,4-oxadiazoline or a 1,2,4-triazole ring, and the quaternary salts thereof, are novel compounds which are pesticidal, notably with respect to acarids, insects and aphids and their eggs and larvae. Compositions containing the compounds are also described as well as processes for their preparation and methods of using them.
