DESCRIPTION OF THE BACKGROUND
WO 94/07492 discloses 4-hydrazinoquinolines and 4-hydrazonoquinolines which are pharmaceutically active.
While 4-quinolinehydrazines are disclosed in the literature, a fungicidal action of these compounds is not reported (cf.: Ann. Chim.(Rome), 46(1956)1050; J. Chem. Soc., 1930, 1999; J. Chem. Soc., 1938, 1083; Yakugaku Zasshi, 65(1945)Ed. B, 431; Farmaco, Ed. Sci., 30 (1975) 965), J. Med. Chem., 12 (1969) 801.
Various phenylazoquinolines are also described in the literature (cf. J. Heterocyclic Chem.; 21 (1984) 501; Ann. Chim.(Rome), 46(1956)1050; J. Chem. Soc; 1084, 1938).
Attl. Accad. Sci. Siena Fisiocrit. (1976) 8, 43-57 reports 4-hydrazonoquinolines which have a microbicidal action. However, these compounds are not reported as having a fungicidal action against plant pathogens.
SUMMARY OF THE INVENTION
It was an object of the present invention to provide quinoline derivatives which have a fungicidal action.
We have found that this object is achieved by compounds of the formula I, which have a good fungicidal activity against plant pathogens.
DETAILED DESCRIPTION OF THE INVENTION
The compounds of the present invention can be prepared by applying known syntheses. The starting compounds can be obtained by known methods.
The compounds of the general formula I are obtained by subjecting the 4-chloroquinolines of the formula II to a condensation reaction with hydrazines of the formula III. ##STR3##
Those quinolines II which are not already known can be obtained by known methods (Tetrahedron 41 (1985) 3033-36, Organic. Syntheses, Col. Vol.3,272 (1955), EP 497371, U.S. Pat. No. 5,240,940).
Those hydrazines III which are not already known can also be obtained by known methods (cf. Houben-Weyl, Volume 10/2, pages 1 to 71 and 169-409, especially 396-399 and 402-405).
The compounds of the general formula I are obtained by subjecting the 4-chloroquinolines II to a condensation reaction with hydrazines of the formula III.
The 4-chloroquinolines II are preferably reacted with the hydrazines in question at elevated temperatures in a suitable diluent. Suitable diluents are inert organic solvents, such as aliphatic hydrocarbons, eg. petroleum ether, aromatic hydrocarbons, eg. toluene or o-, m- or p-xylene, or else alcohols, eg. n-, i- or t-butanol.
The invention also encompasses the salts of the compounds I, in particular the salts of mineral acids or Lewis acids. The type of the salt is normally not critical. Preferred for the purposes of the invention are those salts which do not damage the plants, areas, materials or spaces to be kept free from harmful fungi and which do not adversely affect the activity of the compounds I.
The salts of the compounds I are accessible in a manner known per se, for example by reacting the relevant quinolines I with acids in water or an inert organic solvent at from -80.degree. to 120.degree., preferably 0.degree. to 60.degree. C.
The invention also encompasses the N-oxides of the compounds I. They can be prepared by methods known from the literature (see, for example, Ann. Chim. Rome; 46(1956)1050).
Compounds Ia where R.sup.7, R.sup.8 are a bond can be prepared by methods known from the literature (see Houben-Weyl; Volume 10/3, pages 226-423), for example by coupling aromatic diazonium compounds (p. 226-311), by means of condensation reactions (p. 332-355) or by dehydrating the compounds of the general formula Ib where R.sup.7 and R.sup.8 are hydrogen (p. 377). ##STR4##
Suitable oxidants are inorganic and organic compounds, eg. peroxides, hypohalites, nitrous acid, nitric acid, metal salts, eg. Fe(III) salts, Cu(II) salts, Pb(IV) salts, but also oxygen or air.
Examples of suitable diluents are water, organic and inorganic acids, eg. glacial acetic acid, sulfuric acid or nitric acid; alcohols, eg. methanol or ethanol; halogenated hydrocarbons, aromatic hydrocarbons or else dimethylformamide.
The reaction temperature is generally from 0.degree. to the boiling point of the solvent in question.

The use forms depend on the intended aims; in any case, they should guarantee the finest possible distribution of the active ingredients according to the invention.
Normally, the plants are sprayed or dusted with the active ingredients, or the seeds of the plants are treated with the active ingredients.
The formulations are prepared in a known manner, eg. by extending the active ingredient with solvents and/or carriers, if desired using emulsifiers and dispersants, it also being possible to use other organic solvents and auxiliary solvents if water is used as the diluent. Auxiliaries which are suitable are essentially: solvents such as aromatics (eg. xylene), chlorinated aromatics (eg. chlorobenzenes), paraffins (eg. mineral oil fractions), alcohols (eg. methanol, butanol), ketones (eg. cyclohexanone), amines (eg. ethanolamine, dimethylformamide) and water; carriers such as ground natural minerals (eg. kaolins, clays, talc, chalk) and ground synthetic minerals (eg. highly-disperse silica, silicates); emulsifiers, such as non-ionic and anionic emulsifiers (eg. polyoxyethylene fatty alcohol ethers, alkylsulfonates and arylsulfonates) and dispersants such as lignosulfite waste liquors and methylcellulose.

USE EXAMPLE 1
Activity against powdery mildew of wheat
Leaves of wheat seedlings cv. "Fruhgold" which had been grown in pots were sprayed with an aqueous spray mixture comprising 80% of active ingredient and 20% of emulsifier in the dry matter and, 24 hours after the spray coating had dried, dusted with oidia (spores) of powdery mildew of wheat (Erysiphe graminis var. tritici). The test plants were subseqently placed in the greenhouse at from 20 to 22.degree. C. and a relative atmospheric humidity of from 75 to 80%. After 7 days, the extent of mildew development was determined.
Scoring:
The infected leaf area is indicated as a percentage.
