    Abstract: Compounds of the formula where R and R1 represent hydrogen, R2 and R3 represent methyl or ethyl radicals, Z represents a saturated or unsaturated C2- 4 aliphatic radical, optionally substituted by chlorine, bromine, a carboxyl or alkoxy-carbonyl group and Z represents the anion of an inorganic or organic acid, are used as plant growth regulants for inhibiting the height of plants. The compounds may be applied as an aqueous solution to the soil or to the leaves of the plant, or admixed with conventional fertilizers. Examples describe the treatment of cereal plants with N-b -chloroethyl - N, N - dimethylhydrazinium chloride.ALSO:The invention comprises hydrazinium salts of the formula wherein R and R1 are hydrogen, R2 and R3 are methyl or ethyl radicals, Z is a saturated or unsaturated C2- 4 aliphatic radical optionally substituted by chlorine, bromine, a carboxyl or alkoxycarbonyl group and X represents the anion of an inorganic or organic acid, provided that R2, R3 and Z do not all simultaneously represent the same radical. The compounds in which X is halide may be made by reacting a N,N-dialkylhydrazine with an alkyl halide, which may contain other substituent groups. Haloalkylhydrazinium salts may be converted to other types of substituted hydrazines, e.g. by elimination of hydrogen halide or by nucleophilic aliphatic substitution. The compounds are used as plant growth inhibitors (see Division C1). Examples relate to various hydrazinium bromides and chlorides.

    Abstract: The invention comprises compounds of the general formula and salts and molecular or addition compounds thereof, in which R1 denotes a cyclalkyl radical with more than 6 annular carbon atoms or a tridecyl or alkyl-phenyl radical, R2, R3, R4 and R5 may be identical or different, each denoting an unsubstituted or substituted methylene radical, the substituents being one or two methyl and/or ethyl and/or phenyl groups, with the proviso that, when R1 represents a tridecyl or an alkyl-phenyl radical, at least one of the radicals R2, R3, R4 and R5 is a substitute methylene radical as defined above. The compounds may be prepared by (a) reaction of primary amines or alkanolamines with alkylene oxides to form dialkanolamines which are then cyclised by treatment with dehydrating agents, (b) hydrogenating amination of ketones with primary amino alcohols to form N-substituted alkanolamines which are then reacted with alkylene oxides and cyclised as described above, or (c) reaction of unsubstituted or substituted 2,21-dichloroalkyl ethers with primary amines in the presence of acid-binding agents. The morpholine salts may be prepared by mixing the initial materials, optionally in the presence of solvents, or by treatment of N-substituted dialkanolamines with thionyl halides. The preparation of N-bis-(2-hydroxypropyl)-tridecylamine is described. Many other compounds of the invention are listed. The compounds are fungicides (see Division A5).ALSO:Fungicidal compositions comprise an inert carrier or diluent and a compound of the general formula or salts, or molecular or addition compounds thereof, wherein R1 denotes a cycloalkyl radical with more than 6 annular carbon atoms or a tridecyl or alkyl-phenyl radical, R2, R3, R4 and R5 may be identical or different, each denoting an unsubstituted or substituted methylene radical, the substituents being one or two methyl and/or ethyl and/or phenyl groups, with the proviso that, where R1 represents a tridecyl or an alkyl-phenyl radical, at least one of the radicals R2, R3, R4 and R5 is a substituted methylene radical as defined above (see Division C2). The compositions may be in the form of (a) dusting powders containing inert pulverulent carriers or diluents, (b) solid or liquid compositions for the production of sprays containing inert dispersing agents, wetting agents, adhesives or emulsifiers, or (c) admixtures with other fungicides and/or insecticides. Examples are given.
