The invention relates to novel substituted N-benzoyl-N'-2,3,5-trihalo-4-haloalkoxyphenylureas of formula I ##STR1## wherein R.sub.1 is CF.sub.3, CF.sub.2 CF.sub.3 or CF.sub.2 F.sub.2 CF.sub.3, to the preparation of these compounds and to intermediates for their synthesis. The invention further relates to the use of the novel compounds for use in pest control and to pesticidal compositions which contain at least one compound of formula I as active component. The preferred utility is the control of pests of animals and plants.

N-benzoyl-N'trihalo-haloalkoxyphenylureas and pesticidal compositions

The invention relates to novel substituted carbodiimides of the formula ##STR1## wherein R.sub.1 is hydrogen, halogen, C.sub.1 -C.sub.10 alkyl, C.sub.1 -C.sub.5 alkoxy, C.sub.1 -C.sub.5 alkoxy which is substituted by 1 to 7 halogen atoms, or is C.sub.1 -C.sub.5 alkylthio;

Substituted carbodiimides

The invention relates to a novel 3-acylaminobenzisothiazole-S,S-dioxide of formula I ##STR1## to the preparation thereof, to insecticidal compositions containing said compound and to the use thereof for controlling insects, in particular plant-destructive sucking insects.
