Pyridyl phosphates, compositions containing them and their use as

Compounds of the formula ##STR1## in which R.sup.1 denotes haloalkyl, haloalkenyl or haloalkynyl, (R.sup.2).sub.n denotes H or up to 3 halogens, A denotes N or N.fwdarw.0, R.sup.3 denotes H or alkyl, and Z denotes, inter alia, a carboxyl group or a functional derivative thereof, are valuable herbicides and growth regulators.

Certain perfluoroloweralkoxy-2-pyridyloxy propionates having herbicidal

Compounds of the general formula I ##STR1## in which A denotes a radical of the formula A.sup.1, A.sup.2 or A.sup.3 ##STR2## R.sup.1 to R.sup.3 in each case independently of one another denote hydrogen or halogen,

(Thio)benzoylureas and functional derivatives thereof, processes for

The compounds of the formula (I) ##STR1## in which A denotes N or N.fwdarw.0,

Pyridine derivatives, agents containing same, and the use thereof as

The compounds of the formula I ##STR1## in which R.sub.1 to R.sub.5 denote hydrogen; alkyl, alkoxy, alkylmercapto, alkylsulfinyl, alkylsulfonyl, alkylsulfonyloxy each of which can be halogenated, halogen or nitro, R.sub.6 to R.sub.10 denote hydrogen; alkyl, alkoxy, alkenyloxy, alkylmercapto, alkenylmercapto, alkylsulfonyl or C.sub.3 -hydroxyalkyl each of which can be halogenated, (substituted) benzyloxy, alkoxycarbonyl or NRR', and R.sub.7 and R.sub.8 together can form a (substituted) alkylenedioxy radical,

N-carbamoylaryl carboximidic acid esters, and their use as insecticides

The compounds of the formula I ##STR1## in which A denotes N or N.fwdarw.O, Z denotes O or NH, R denotes H, (halo)alkyl, (halo)alkenyl, (halo)alkynyl or alkoxycarbonyl, R.sup.1 denotes hydrogen, halogen, amino, --NHOH, hydroxyl, (substituted) phenylazo or a radical of the formulae Y=C=N--, Y.sup.1 Y.sup.2 C.dbd.N--, Y.sup.3 NH-- or ##STR2## K denotes 0 or 1, and m and n, independently of one another, denote a number from 1 to 4, with the proviso that, when Z-R denotes OH or NH.sub.2, (R.sup.1).sub.n denotes at least one radical of the formula ##STR3## or represents two radicals, in the 5 or 6 position of the heterocyclic ring, which, in the 5 position, denote halogen and, in the 6 position, denote a radical of the group comprising halogen, amino, hydroxyl or phenylazo, which may be substituted as specified above, are valuable intermediates in the synthesis of plant protection agents.
