Abstract: A process for protecting cultivated plants against aggressive agricultural chemicals is described in which oxime derivatives of the formula ##STR1## are used as antidotes. Either the cultivated area for the cultivated plants or the cultivated plants themselves or parts of the plant (seeds, tubers, stem parts and the like), as desired, can be treated with these oxime derivatives, which are used as a dressing.Ar is a phenyl radical of the formula ##STR2## or Ar is also a 5-membered to 10-membered heterocyclic radical which contains not more than three identical or different hetero-atoms N, O and/or S and which can be bonded via a C.sub.1 - to C.sub.3 -aliphatic chain to the remainder of the molecule and which is substituted by R.sub.1, R.sub.2 or R.sub.3 and can be substituted by oxo or thiono; X is hydrogen, CN, halogen, C.sub.1 -C.sub.

Abstract: Compounds of the formula ##STR1## wherein R.sub.1 and R.sub.2 independently of one another are each a chlorine atom or the methyl group, Y is the group ##STR2## or --CH.dbd.N--R.sub.5, in which R.sub.3 is methyl or ethyl, R.sub.4 is alkyl having 1 to 4 carbon atoms, alkoxy having 1 or 2 carbon atoms, alkylthio having 1 to 4 carbon atoms, or phenyl, X is an oxygen atom or a sulfur atom, and R.sub.5 is an unsubstituted or substituted pyridinyl group which is linked by way of one of its carbon atoms, to the main part of the molecule, and which has substituents selected from the group comprising halogen and alkyl having 1 to 4 carbon atoms, including the acid addition salts thereof, processes for producing the novel compounds by reaction of 2-(anilinomethyl)-2-imidazoline derivatives either with (thio)phosphoric acid dialkyl ester halides or alkyl(thio) phosphonic acid alkyl ester halides, or with N-pyridinylformiminoalkoxy derivatives.
