Abstract: The invention relates to a selection of succinic acid imides that have, in the 2-position, alkoxy, alkoxyalkyl or acyloxy substituents having up to 4 carbon atoms and the imine components of which are derived from aliphatic amines having up to 5 carbon atoms or from aniline optionally having up to 2 substituents. The succinic acid imides according to the invention are used as fungicides. A method for their manufacture is also disclosed.

Abstract: The invention relates to fungicidally active compositions that contain at least one compound of the general formula ##STR1## and/or a compound of the formula ##STR2## in which: A denotes the --CH.dbd.CH-- or --C.tbd.C-- group and R.sub.1 and R.sub.2 represent hydrogen or methyl.The active substances according to the invention can be obtained by reacting correspondingly substituted succinic acids, or acid halides, anhydrides or esters thereof, with 3,5-dichloroaniline.

Abstract: A 1-(3-pyridyl)-2,2,2-trihaloethyl compound of the formula I ##STR1## in which n is 0 or 1, R represents methyl and X is iodide, R' represents a radical of the formula II ##STR2## wherein V, Y and Z each represent a chlorine or bromine atom, A represents a radical of the general formula III ##STR3## in which B' is oxygen or sulphur and B stands for a member of the group consisting of an aliphatic radical having from 1-10 C-atoms of the group consisting of alkenyl radicals and alkyl radicals of the branched and straight chain type, the phenyl radical, an aralkyl radical having from 7-12 C-atoms and an amino group of the general formula IV ##STR4## in which F and D are identical or different, and represent a member of the group consisting of hydrogen, aliphatic radicals of the branched or straight chain type and having from 1-10 C-atoms, the phenyl radical, a substituted phenyl radical containing at least one substituent selected from the group consisting of lower alkoxy, lower alkanoyl, lower alkyl ester, COOH

Abstract: 1-(3-Pyridyl)-2,2,2-trihaloethyl compounds of the general formula I ##STR1## in which n is 0 or 1, R represents oxygen, hydrogen or an organic radical having at the most 12 C-atoms, m is 0 when R is oxygen, m is 1/2 or 1 when R is hydrogen or an aliphatic or aralkyl radical, and X represents a negative ion, R' represents a radical of the general formula II ##STR2## wherein V, Y, Z represent chlorine or bromine and may be identical or different, but are preferably identical; A represents hydrogen or a radical of the general formula III ##STR3## wherein B' is oxygen or sulphur, and B stands for an organic radical having up to 12 C atoms, or for an amino group of the general formula IV ##STR4## wherein F and D are identical or different, and represent hydrogen or organic radicals having at most 12 C-atoms; A may further be a sulphonyl group of the general formula --SO.sub.2 --B, in which B has the same meaning as in formula III.
