The invention relates to known and to new acylaminosalicylamides, to a plurality of processes for their preparation and to their use as pesticides. The present application furthermore relates to new intermediates, to a plurality of processes for their preparation and to their use as pesticides.

Acylaminosalicylic acid amides and their uses as pesticides

A method of combating arthropods and nematodes which comprises applying thereto, to a habitat thereof or to an area from which they are to be excluded an arthropodicidally or nematocidally effective amount of at least one long-chain halogenoolefine of the formula (I) ##STR1## in which R represents a straight-chain or branched alkyl radical with 8 to 25 carbon atoms in the straight chain, the alkyl radical optionally being interrupted once or several times by a --C.tbd.C-- and/or ##STR2## in which Z and Z.sup.1 are identical or different and represent hydrogen or methyl and

Halogenoolefin pesticides

The novel compound 2,3,5,6-Tetrafluorobenzyl (+)1R-trans-2,2-dimethyl-3-(2,2-dichlorovinyl)-cyclopropanecarboxylate of the formula ##STR1## is highly active insecticidally.

2,3,5,6-Tetrafluorobenzyl (+)

Halogenoolefins as arthropocides and nematocides

2,3,5,6-Tetrafluorobenzoic acid is prepared by hydrogenolysis of pentafluorobenzoic acid (esters).

Process for the preparation of 2,3,5,6-tetrafluorobenzoic acid

Novel insecticidally and acarididally active vinylcyclopropanecarboxylic acid esters of the formula ##STR1## in which R represents alkylthio, alkylsulphinyl, alkylsulphonyl,

Vinylcyclopropanecarboxylic acid esters

Pesticidal compositions useful in protecting plants and also in the hygiene field are disclosed. The new tetramethylcyclopropanecarboxylates have the formula ##STR1## where R represents mercapto, methylthio, alkylsulphenyl or alkylsulphonyl.

Tetramethylcyclopropanecarboxylates

A process for the preparation of the enantiomeric pairs (1R-3R-.alpha.S+1S-3S-.alpha.R) and (1R-3S-.alpha.S+1S-3R-.alpha.R) from a mixture of all 8 stereoisomers of the compound .alpha.R/S-cyano-3-phenoxy-4-fluorobenzyl 3R/S-(2,2-dichlorovinyl)-2,2-dimethyl-1R/S-cyclopropanecarboxylate, comprising dissolving the mixture in a secondary or tertiary alkylamine having 2-6 C atoms per alkyl radical, subjecting the solution to crystallization whereby the enantiomeric pairs (1R-3R-.alpha.S+1S-3S-.alpha.R) and (1R-3S-.alpha.S+1S-3R-.alpha.R) crystallize out from the solution, and separating the crystallized material. The crystals are enriched in the most active components.

Process for the preparation of certain enantiomeric pairs of

Novel Substituted benzoxazine derivatives of the formula ##STR1## in which X is oxygen or suophur, and

Substituted benzoxazine derivatives and fungicidal use

A pentafluorobenzyl 2,2-dimethyl-3-vinylcyclopropane carboxylate of the formula ##STR1## in which R is hydrogen or halogen, and

Combating arthropods with perfluorobenzyl

Pesticidal compositions comprise synergistic mixtures of active compounds 1R-(-)-[(pentafluorophenyl)-methyl]-3S-3-(2,2-dichloroethenyl)-2,2-dimethy lcyclopropanecarboxylate and O,O-dimethyl O-2,2-dichlorovinyl phosphate (dichlorvos) and, if appropriate, O-isopropoxyphenyl N-methylcarbamate (propoxur). These compositions may be used for combating arthropods.

Synergistic arthropodicidal composition

Substituted 3-(1,2-dibromo-alkyl)-2,2-dimethyl-cyclopropane-1-carboxylic acid esters of the formula ##STR1## in which R.sup.1 is halogen or optionally substituted phenyl or optionally substituted alkyl,

Combating pests with substituted

1-Aryl-cyclopropane-1-carboxylic acid esters of the formula ##STR1## in which R.sup.1 represents a hydrogen atom, a cyano radical or an alkyl, alkenyl or alkinyl radical within each case up to 7 carbon atoms, and

Combating pests with 1-aryl-cyclopropane-1-carboxylic acid esters

A 3-(2,chloro-3,3,4,4,4-pentafluoro-1-butenyl)-2,2-dimethyl-cycloproanecarbo xylic acid ester of the formula ##STR1## in which R.sup.1 represents hydrogen, cyano or an alkyl, alkenyl or alkynyl radical with in each case up to 4 carbon atoms, and
