Abstract: Compounds of the formula ##STR1## wherein R.sub.1 is fluorine, chlorine, bromine or iodine; and A is 2,6-difluorophenyl, 2-chlorophenyl, 2-chloro-6-fluorophenyl, 2,6-dichlorophenyl or 2-fluorophenyl,with the proviso that when R.sub.1 is chlorine, A is other than 2,6-dichlorophenyl, useful as pesticides.

Abstract: The invention provides new solvent concentrates of the fungicidally active substance triforine (N,N'-bis[1-formamido-2,2,2-trichloroethyl]-piperazine) characterized by good solubility and good stability to cold and heat.

Abstract: Benzoyl ureas of the formula ##STR1## are prepared by starting from benzoyl derivatives of the formulaQ-COHalwhich are converted via the corresponding azides into the isocyanates, which are in turn reacted with corresponding benzamides.

Abstract: Liquid, water-miscible, fungitoxic and acaricidal emulsion concentrates containing triforine and, as an emulsifier, a member of a certain group of salts of alkylbenzene-sulfonic acids, preferably of n-dodecylbenzenesulfonic acid or tetrapropylenebenzenesulfonic acid; the concentrates exhibit markedly improved stability.

Abstract: Compounds of the formula ##STR1## wherein R.sub.1 and R.sub.2 are each hydrogen, halogen or lower alkyl, attached to the 3-, 4- or 5-positions of the phenyl ring,R.sub.3 is halogen, lower alkyl or lower alkoxy, attached to the 3- or 4-position of the phenyl ring, andR.sub.4 is hydrogen, halogen or lower alkyl, attached to the 4- or 5-position of the phenyl ring;Provided, however, that the two phenyl moieties are other than both 4-chloro- or 4-methyl-substituted at the same time; the compounds are useful as insecticides and acaricides.

Abstract: Compounds of the formula ##STR1## wherein A is oxygen or --NH--, andR is straight or branched alkyl of 2 to 22 carbon atoms or straight or branched alkenyl of 3 to 18 carbon atoms,And acid addition salts thereof; the compounds as well as the salts are useful as acaricides.
