This invention refers to chemistry, in particular to substitutad pyrimidine compounds, to their production and use as pesticides . Technical result of the invention is to increase pesticidal and namely acasicidal activity of the compounds and composition against vermin insects and ectoparasites of the cattle, including white flies and mosguitoes.. The essence of the infention is in that there is provided the production of the compounds of formula (I) in which X1 and X2 each represents oxygen; S(O)n , being 0, 1 or 2 ; or CO,CH2 or NR, R being hydrogen or alkyl; R1 and R10 are each hydrogen, or halogen; R2 and R9 are each hydrogen, halogen, cyano, nitro, alkyl, haloalkyl, alkoxy, alkylthio, amino, mono - or di-alkylamino, alkoxyalkyl, haloalkoxy¬alkyl or alkoxycarbonyl; R3 and R8 are each hydrogen chlorine, alkyl, haloalkyl, haloalkenyl, haloalkynyl, haloalkoxy, haloalkoxy carbonyl, halo¬alkyl¬thio, halo¬alkoxyalkyl, haloakylsulphonyl, or haloalkylsulphonyl nitro or nitro or cyano; R4 and R7 are each hydro-gen halogen, alkyl or alkoxy; R5 is hydrogen halogen, cyano, alkyl, haloalkyl, alkoxy, alkylthio, alkylsulphinyl or phenyl; and R6 is hedrogen or, when R5 is hydrogen, alkyl; provided that either each phenyl is unsubstituted or at least one of R3 and R8 is not hydrogen, have useful pesticidal activity. |
