INSECTICIDE, ACARICIDE AND OVICIDE COMPOSITIONS CONTAINING PHENYL-BENZOYL-UREA DERIVATIVES AS ACTIVE COMPONENTS AND PROCESS FOR PRODUCING THE ACTIVE COMPONENTS

摘要

The invention relates to novel substituted N-phenyl-N-tetrahydropyranyl-N'-benzoylureas of the formula wherein R1 is hydrogen, halogen, C1-C6alkyl, C1-C3haloalkyl containing 1 to 7 halogen atoms, C1-C6alkoxy, C1-C6alkylthio, C1-C3haloalkoxy containing 1 to 7 halogen atoms, nitro, cyano, ethynyl or one of the groups wherein R5, R6 and R7 are C1-C6alkyl; R2, R3 and R4 are each independently hydrogen, halogen, C1-C6alkyl, C1-C3haloalkyl containing 1 to 7 halogen atoms, C1-C6alkoxy, C1-C6alkylthio, C1-C3haloalkoxy containing 1 to 7 halogen atoms, nitro, cyano, ethynyl or one of the groups wherein R5, R6 and R7 are C1-C6alkyl, wherein -A- is -O- or -S-, R8 is halogen, methyl, nitro, CF3 or cyano and n is 0, 1, 2 or 3, or wherein each of R9 and R10 independently is hydrogen, chlorine, trifluoromethyl or an ethyl radical perhalogenated with fluorine and/or chlorine; and U, X, Y, Z and W are each independently hydrogen, halogen, C1-C3alkyl, C1-C3alkoxy or C1-C3alkylthio, to the preparation of these compounds and to compositions containing them for controlling insects and representatives of the order Acarina. The novel compounds exhibit larvicidal activity, especially against plant-destructive insects.
