The present invention relates to a process Eor combatting fungi by applica-tion of new diamine derivatives, and to fungicide compositions containing such derivatives as active ingredients.

The d;am;ne der;vat;ves of the formula I are obtained, for example, by a process wherein a compound of the formula II, Rln R

where A, R1, R2, R3, R4, ~5 and n have the above meanings, is reacted w;th a compound R6Z,where R6 and Z
have the above mean;ngs.
The react;on ;s carr;ed out in the presence or absence of a solvent or d;luent, at from 20 to 150C, preferably from 30 to 140C. The reaction ;s advanta-geously carr;ed out us;ny equ;molar amounts of the start;ngmater;al of the formula II and the compound R6Z.

The preparat;on of the starting compounds o~ the formula II by a convent;onal process ;s described together w;th the synthesis of the novel compounds of the formula I.
Examples of su;table quatern;zing agents o~ the formula R6Z, in addition to the alkyl, alkenyl, alkynyl, benzyl and aralkyl haLides, are dimethyl-sul ate, diethyl sulfate and sulfonates of the formula R-S03-R6~ where R~

~2~35~L8 The diamine derivative used as active ingredlents in the process and compositions according to the invention have a s-trong action on microorganisms. They are especially suitable for preventing and curing plant diseases caused by fungi, e.g., Botrytis cinerea in grapes and strawberries, Monilia fructigena in apples, Phytophtora infestans in potatoes and tomatoes, Plasmopara viticola in grapes, and Alternaria solani in tomatoes.
The fungicidal or bactericidal agents contain from 0.1 to 95, and prererably from 0.5 to 90, wt~ of active ingredient. Depending on the type of effect desired, the application rates are from 0.1 to 5 kg of active ingredient per hectare.
The imidazolium salts according to the invention are also suitable for industrial purposes, e.g., as wood preservatives. The compounds have also been found to have not only a fungicidal action, but also a bac-tericidal action -they are also suitable as such for use in crop protection and as industrial microbicides. For instance the following micro-organisms may be combated:Staphylococcus aureus, Escherichia coli, Klebsiella pneumoniae, Citrobacter freundii, Proteus vulgatis, Pseu domonas aeruginosa, Pseudomonas luorescens, Xanthomonas vesicatoria, Xanthomonas malvaccarum, Erwinia carotovora, Erwinia amylovora, Desulfovibrio desu~furicans, Streptoverticillium rubrire-ticuli, Aspergillus niger, Aspergillus versicolor, Penicillium funiculosum, Paecilomyces variotii, Trichoderma viride, Chaetomium globosum, Candida albicans, Geotrichum candidans, Monilia sitophila, Scen0desmus ~uadricauda, Chlorella vulgaris and Nostoc rnuscorum.

__ 3 5 ~ ~
- 22 - O.Z. 0050~35932 The usual use concentrations are from 0.01 to 1% Oe actlve ingredient, based on the weight of the material to be protected;
when the active lngredients are used ~or water treatment in oil production, ln swimmlng baths, cooling towers, air humidifylng unlts, flower preservatives or in the paper industry, amounts of from 5 to 100 ppm are sufficlent to suppress microorganism develop-ment.

The agents according to the in~ention may al~o be mixed and applied wlth other actlve lngredlents, e.g., herbicldes, insec-ticldes, growth regulators, fungicides and fertillzers. When mi~ed with other funglcldes, the spectrum of fungicidal action is in many cases increased; with a number of these funglcidal composl tions, synergistic effects also occur; i.e., the funglcidal action of the combination product i5 greater than the e~fect of the indi-vidual components added together.
~ xamples of ~ungicides which may be combined wlth the com-pounds according to the invention are: sulfur, dithiocarbamat,es and their derivatives, e.g. iron(III) dimethyldithlocarbamate, zinc dimethyldlthlocarbamate, manganese zinc N,N-ethylenediamine--bls-dithlocarbamate, zinc N,N-ethglene-bis-dithiocarbamate, tetra-methylthiuram disulflde, the ammonia comple~ of zlnc N,N-ethylene--bls--dlthiocarbamate and N,N'-polyethylene-bls-(thlocarbamoyl)--di3ulfide, zlnc N,N'-propylene-bis-dlthiocarbamate, and the ammonia complex of zlnc N,Nt-propylene-bls-dithlocarbamate and N-N'-polypropylene-bis-(thiocarbamoyl)-disulfide; nltro derlv-atlves, e.g. dinitro-(l-methylheptyl)-phenyl crotonate, 2-sec.-.
