It has now surprisingly been found that the use of compounds of formula I
of the invention prevents plants from being attacked by harmful microorganisms and thus guards against damage to plants caused by such attack. A characteristic of the active ingredients of the invention is that the protection of the plants can stem both from the direct action on the plant-damaging microorganisms by means of foliar application or soil application and from the activation and stimulation of the plant's own defence system (immunisation). The great advantage of the compounds of formula I is that it is possible to ensure the continued health of plants treated with these substances also through their own resources without using further microbicidal substances during the vegetation period.
Consequently it is possible by using the active ingredients of the invent:Lon to avoid the adverse side effects that may occur with direct parasite control using chemical substances, for example on the one hand as a result of damage to the useful plants (phytotoxicity) and on the other hand as a result of causing the harmful microorganisms to develop a resistance; consequently growth of the useful plants is advantageously completely undisturbed.
Owing to the double action of the compounds of formula I of the invention, that is to say on the one hand the direct control of the plant pathogens and on the other hand the increase in the general capacity of plants treated with these active ingredients to defend themselves as a result of immunisation, it is possible to achieve a broadly bascd protection of plants against disease. The use of the active ingredients of the invention is therefore especially suitable for practical application. Furthermore, the systemic activity peculiar to the compounds of formula I results in the protective effect being extended also to growing parts of the treated plants.

2~3~17 The generally plant-protecting activity of the active ingredients of the invention is effective, for example, against the phytopathogenic fungi belonging to the following classes: Fungi imperfecti (for example ~otrytis, Helminthosporium, Fusarium, Septoria, Cercospora and Alternaria); Basidiomycetes (for example of the genera Hemileia, Rhizocotonia, Puccinia); Ascomycetes (for example Venturia, Podosphaera, Erysiphe, Monilinia, Uncinula).
In addition, the active ingredients can be used with particular advantage against the following harmful organisms:
fungi, such as, for example, Oomycetes (for example Plasmopara viticola, Phytophthora infestans, Peronospora tabacina, Pseudoperonospora, Bremia letucae), Fungi imperfecti (for example Colletotrichum lagenarium, Piricularia oryzae, Cercospora nicotinae), Ascomycetes (for example Venturia inaequalis);

2~ 7 According to a special arrangement of this process for the preparation of compounds of formula I, the free acid of Eormula II' is reacted with an alkylating agent of formula IV in the presence of potassium fluoride in a dipolar aprotic solvent, such as, for example, N,N-dimethylformamide, dimethyl sulfoxide, N-methylpyrrolidone or tetramethylurea.
In the preparation processes described above, the radicals or symbols A, Q1, Qz, Rl, Rz, X1, Xz, X3 and Y appearing therein are as defined for formula I.
Suitable bases are organic and inorganic bases, for example tertiary amines, such as trialkylamines (trimethylamine, triethylamine, tripropyl-amine etc.), pyridine bases (pyridine, 4-dimethylaminopyridine, 4-pyrrolidylaminopyridine, collidine), oxides and hydroxides, carbonates and hydrogen carbonates of alkali metals and alkaline earth metals, and also alkali acetates.
Suitable solvents and diluents that are inert towards the reactions areused as reaction media in accordance with the respective reaction conditlons. The following may be mentioned as examples: aliphatic and aromatic hydrocarbons, such as benzene, toluene, xylenes, petroleum ether; halogenated hydrocarbons, such as chlorobenzene, methylene chloride, ethylene chloride, chloroform~ carbon tetrachloride, tetra-chloroethylens ethers and ethereal compounds, such as dialkyl ethers (diethyl ether, diisopropyl ether, tert.-butyl methyl ether etc.), anisole, dioxane, tetrahydrofuran; nitriles, such as acetonitrile, propionitrile; N,N-dialkylated amides, such as dimethylformamide;
ketones, such as acetone, diethyl ketone, methyl ethyl ketone; and also mixtures of such solvents with one another.
The alcohols or thiols of formula III used as starting compounds and also compounds of ~ormula IV are mostly known or can be prepared according to methods known to the person skilled in the art, as described, for example, in the following:

The microbicidal compositions that are used within the scope of the invention for protecting plants against disease and that contain the compounds of formula I as active ingredients are to be considered as part of the invention.
The active ingredients of formula I are normally used in the form of compositions and can be applied to the plant or the locus thereof, simultaneously or in succession, with further active ingredients. These further active ingredients can be fertilisers or micronutrient donors or other preparations that influence plant growth. They can, however, also be selective herbicides, insecticides, fungicides, bactericides, nematicides, molluscicides or mixtures of several of these preparations, if desired together with further carriers, surfactants or other appli-cation-promoting adjuvants customarily employed in the art of formulation.
Suitable carriers and adjuvants can be solid or liquid and correspond to the substances ordinarily employed in formulation technology, e.g.
natural or regenerated mineral substances, solvents, dispersants, wetting agents, tackifiers, thickeners, binders or fertilisers.
One method of applying an active ingredient of formula I or an agro-chemical composition containing at least one of those active ingredients is application to the plant (foliar application). The active ingredients of formula I can, however, also penetrate the plant through the roots via the soil (soil application) if the locus of the plant is impregnated with a liquid formulation, or if the compounds are applied in solid form to the soil, for example in granular form. Tlle compounds of formula I may, however, also be applied to seeds (coating), either by impregnating the seeds with a liquid formulation of the act1ve ingredient or coating them :~ : : .... :
,.,: : ~ : : .
: ~
3~17 with a solid formulation (dressing~. In addition, in special cases further types of application are possible, for example the selective treatment of the plant stems or buds.
The compounds of formula I are used in unmodified form or, preferably, together with the adjuvants conventionally employed in the art of for-mulation, and are for this purpose formulated in known manner e.g. into emulsifiable concentrates, coatable pastes, directly sprayable or dilutable solutions, dilute emulsions, wettable powders, soluble powders, dusts, granulates, and also encapsulations in e.g. polymer substances. As with the nature of the compositions, the methods of application, such as spraying, atomising, dusting, scattering, coating or pouring, are chosen in accordance with the intended objecti~es and the prevailing circum-stances. Advantageous rates of application are normally from 50 g to 5 kg of active ingredient (a.i.) per hectare, preferably from 100 g to 2 kg a.i./ha, most preferably from 100 g to 600 g a.i./ha.
The formulations, i.e. the compositions, preparations or mixtures containing the compound (active ingredient) of formula I and, where appropriate, a solid or liquid adjuvant, are prepared by homogeneously mixing and/or grinding the active ingredients with extenders, e.g.
solvents, solid carriers and, where appropriate, surface-active compounds (surfactants).
Suitable solvents are: aromatic hydrocarbons, preferably the fractions containing 8 to 12 carbon atoms, e.g. xylene mixtures or substituted naphthalenes, phthalates such as dibutyl phthalate or dioctyl phthalate, aliphatic hydrocarbons such as cyclohexane or paraffins, alcohols and glycols and their athers and esters, such as ethanol, ethylene glycol, ethylene glycol monomethyl or monoethyl ether7 ketones such as cyclohexanone, strongly polar solvents such as N-methyl-2-pyrrolidone, dimethyl sulfoxide or dimethylformamide, as well as vegetable oils or epoxidised vegetable oils, such as epoxidised coconut oil or soybean oil;
or water.
'~
,:
- 14 - 2~3~7 The solid carriers used e.g. for dusts and dispersible powders, are normally natural mineral fillers such as calcite, talcum, kaolin, montmorillonite or attapulgite. In order to improve the physical properties it is also possible to add highly dispersed silicic acid or highly dispersed absorbent polymers. Suitable granulated adsorptive carriers are porous types, for example pumice, broken brick, sepiolite or bentonite; and suitable nonsorbent carriers are, for example, calcite or sand. In addition, a great number of pregranulated materials of inorganic or organic nature can be used, e.g. especially dolomite or pulverised plant residues.
Depending on the nature of the active ingredient of formula I to be formulated, suitable surface-active compounds are non-ionic, cationic and/or anionic surfactants having good emulsifying, dispersing and wetting properties. The term "surfactants" will also-be understood as comprising mixtures of surfactants.
Cationic surfactants are especially quaternary ammonium salts that contain as N-substituent at least one alkyl radical having from ~ to 22 carbon atoms and as further substituents lower, unsubstltuted or halogenated alkyl, benzyl or hydroxy-lower alkyl radicals.
Both so-called water-soluble soaps and also water-soluble synthetic surface-active compounds are suitable anionic surfactants.
Suitable soaps are the alkali metal salts, alkaline earth metal salts or unsubstituted or substituted ammonium salts of higher fatty acids (C1o-C22), e.g. the sodium or potassium salts of oleic or stearic acid or of natural fatty acid mixtures which can be obtained e.g. $rom coconut oil or tallow oil.
Suitable synthetic surfactants are especially fatty alcohol sulfonates,fatty alcohol sulfates, sulfonated benzimidazole derivatives or alkylsulfonates. The fatty alcohol sulfonates or sulfates are usually in the form of alkali metal salts, alkaline earth metal salts or unsubstituted or substituted ammonium salts and contain an alkyl radical having from 8 to 22 carbon atoms.

::: : . :, ,' -. : : .
3~
Non-ionic surfactants are preferably polyglycol ether derivatives of aliphatic or cycloaliphatic alcohols, saturated or unsaturated fatty acids and alkylphenols, said derivatives containing 3 to 30 glycol ether groups and 8 to 20 carbon atoms in the (aliphatic) hydrocarbon moiety and 6 to 18 carbon atoms in the alkyl moiety of the alkylphenols.
The compositions may also contain further auxiliaries, such as stabilisers, antifoams, viscosity regulators, binders, tackifiers as well as fertilisers or other active ingredients for achieving spscial effects.
The agrochemical compositions usually contain 0.1 to 99 % by weight, preferably 0.1 to 95 % by weight, of a compound of formula I, 99.9 to 1 %
by weight, preferably 99.8 to 5 % by weight, of a solid or liquid adjuvant, and 0 to 25 % by weight, preferably 0.1 to~25 % by weight, of a surfactant, The following Examples serve to illustrate the invention without implying any limitation.

It has now surprisingly been found that the use of compounds of formula I
of the invention prevents plants from being attacked by harmful microorganisms and thus guards against damage to plants caused by such attack. A characteristic of the active ingredients of the invention is that the protection of the plants can stem both from the direct action on the plant-damaging microorganisms by means of foliar application or soil application and from the activation and stimulation of the plant's own defence system (immunisation). The great advantage of the compounds of formula I is that it is possible to ensure the continued health of plants treated with these substances also through their own resources without using further microbicidal substances during the vegetation period.
Consequently it is possible by using the active ingredients of the invent:Lon to avoid the adverse side effects that may occur with direct parasite control using chemical substances, for example on the one hand as a result of damage to the useful plants (phytotoxicity) and on the other hand as a result of causing the harmful microorganisms to develop a resistance; consequently growth of the useful plants is advantageously completely undisturbed.
Owing to the double action of the compounds of formula I of the invention, that is to say on the one hand the direct control of the plant pathogens and on the other hand the increase in the general capacity of plants treated with these active ingredients to defend themselves as a result of immunisation, it is possible to achieve a broadly bascd protection of plants against disease. The use of the active ingredients of the invention is therefore especially suitable for practical application. Furthermore, the systemic activity peculiar to the compounds of formula I results in the protective effect being extended also to growing parts of the treated plants.

2~ 7 According to a special arrangement of this process for the preparation of compounds of formula I, the free acid of Eormula II' is reacted with an alkylating agent of formula IV in the presence of potassium fluoride in a dipolar aprotic solvent, such as, for example, N,N-dimethylformamide, dimethyl sulfoxide, N-methylpyrrolidone or tetramethylurea.
In the preparation processes described above, the radicals or symbols A, Q1, Qz, Rl, Rz, X1, Xz, X3 and Y appearing therein are as defined for formula I.
Suitable bases are organic and inorganic bases, for example tertiary amines, such as trialkylamines (trimethylamine, triethylamine, tripropyl-amine etc.), pyridine bases (pyridine, 4-dimethylaminopyridine, 4-pyrrolidylaminopyridine, collidine), oxides and hydroxides, carbonates and hydrogen carbonates of alkali metals and alkaline earth metals, and also alkali acetates.
Suitable solvents and diluents that are inert towards the reactions areused as reaction media in accordance with the respective reaction conditlons. The following may be mentioned as examples: aliphatic and aromatic hydrocarbons, such as benzene, toluene, xylenes, petroleum ether; halogenated hydrocarbons, such as chlorobenzene, methylene chloride, ethylene chloride, chloroform~ carbon tetrachloride, tetra-chloroethylens ethers and ethereal compounds, such as dialkyl ethers (diethyl ether, diisopropyl ether, tert.-butyl methyl ether etc.), anisole, dioxane, tetrahydrofuran; nitriles, such as acetonitrile, propionitrile; N,N-dialkylated amides, such as dimethylformamide;
ketones, such as acetone, diethyl ketone, methyl ethyl ketone; and also mixtures of such solvents with one another.
The alcohols or thiols of formula III used as starting compounds and also compounds of ~ormula IV are mostly known or can be prepared according to methods known to the person skilled in the art, as described, for example, in the following:

The microbicidal compositions that are used within the scope of the invention for protecting plants against disease and that contain the compounds of formula I as active ingredients are to be considered as part of the invention.
The active ingredients of formula I are normally used in the form of compositions and can be applied to the plant or the locus thereof, simultaneously or in succession, with further active ingredients. These further active ingredients can be fertilisers or micronutrient donors or other preparations that influence plant growth. They can, however, also be selective herbicides, insecticides, fungicides, bactericides, nematicides, molluscicides or mixtures of several of these preparations, if desired together with further carriers, surfactants or other appli-cation-promoting adjuvants customarily employed in the art of formulation.
Suitable carriers and adjuvants can be solid or liquid and correspond to the substances ordinarily employed in formulation technology, e.g.
natural or regenerated mineral substances, solvents, dispersants, wetting agents, tackifiers, thickeners, binders or fertilisers.
One method of applying an active ingredient of formula I or an agro-chemical composition containing at least one of those active ingredients is application to the plant (foliar application). The active ingredients of formula I can, however, also penetrate the plant through the roots via the soil (soil application) if the locus of the plant is impregnated with a liquid formulation, or if the compounds are applied in solid form to the soil, for example in granular form. Tlle compounds of formula I may, however, also be applied to seeds (coating), either by impregnating the seeds with a liquid formulation of the act1ve ingredient or coating them :~ : : .... :
,.,: : ~ : : .
: ~
3~17 with a solid formulation (dressing~. In addition, in special cases further types of application are possible, for example the selective treatment of the plant stems or buds.
The compounds of formula I are used in unmodified form or, preferably, together with the adjuvants conventionally employed in the art of for-mulation, and are for this purpose formulated in known manner e.g. into emulsifiable concentrates, coatable pastes, directly sprayable or dilutable solutions, dilute emulsions, wettable powders, soluble powders, dusts, granulates, and also encapsulations in e.g. polymer substances. As with the nature of the compositions, the methods of application, such as spraying, atomising, dusting, scattering, coating or pouring, are chosen in accordance with the intended objecti~es and the prevailing circum-stances. Advantageous rates of application are normally from 50 g to 5 kg of active ingredient (a.i.) per hectare, preferably from 100 g to 2 kg a.i./ha, most preferably from 100 g to 600 g a.i./ha.
The formulations, i.e. the compositions, preparations or mixtures containing the compound (active ingredient) of formula I and, where appropriate, a solid or liquid adjuvant, are prepared by homogeneously mixing and/or grinding the active ingredients with extenders, e.g.
solvents, solid carriers and, where appropriate, surface-active compounds (surfactants).
Suitable solvents are: aromatic hydrocarbons, preferably the fractions containing 8 to 12 carbon atoms, e.g. xylene mixtures or substituted naphthalenes, phthalates such as dibutyl phthalate or dioctyl phthalate, aliphatic hydrocarbons such as cyclohexane or paraffins, alcohols and glycols and their athers and esters, such as ethanol, ethylene glycol, ethylene glycol monomethyl or monoethyl ether7 ketones such as cyclohexanone, strongly polar solvents such as N-methyl-2-pyrrolidone, dimethyl sulfoxide or dimethylformamide, as well as vegetable oils or epoxidised vegetable oils, such as epoxidised coconut oil or soybean oil;
or water.
'~
,:
- 14 - 2~3~7 The solid carriers used e.g. for dusts and dispersible powders, are normally natural mineral fillers such as calcite, talcum, kaolin, montmorillonite or attapulgite. In order to improve the physical properties it is also possible to add highly dispersed silicic acid or highly dispersed absorbent polymers. Suitable granulated adsorptive carriers are porous types, for example pumice, broken brick, sepiolite or bentonite; and suitable nonsorbent carriers are, for example, calcite or sand. In addition, a great number of pregranulated materials of inorganic or organic nature can be used, e.g. especially dolomite or pulverised plant residues.
Depending on the nature of the active ingredient of formula I to be formulated, suitable surface-active compounds are non-ionic, cationic and/or anionic surfactants having good emulsifying, dispersing and wetting properties. The term "surfactants" will also-be understood as comprising mixtures of surfactants.
Cationic surfactants are especially quaternary ammonium salts that contain as N-substituent at least one alkyl radical having from ~ to 22 carbon atoms and as further substituents lower, unsubstltuted or halogenated alkyl, benzyl or hydroxy-lower alkyl radicals.
Both so-called water-soluble soaps and also water-soluble synthetic surface-active compounds are suitable anionic surfactants.
Suitable soaps are the alkali metal salts, alkaline earth metal salts or unsubstituted or substituted ammonium salts of higher fatty acids (C1o-C22), e.g. the sodium or potassium salts of oleic or stearic acid or of natural fatty acid mixtures which can be obtained e.g. $rom coconut oil or tallow oil.
Suitable synthetic surfactants are especially fatty alcohol sulfonates,fatty alcohol sulfates, sulfonated benzimidazole derivatives or alkylsulfonates. The fatty alcohol sulfonates or sulfates are usually in the form of alkali metal salts, alkaline earth metal salts or unsubstituted or substituted ammonium salts and contain an alkyl radical having from 8 to 22 carbon atoms.

::: : . :, ,' -. : : .

Non-ionic surfactants are preferably polyglycol ether derivatives of aliphatic or cycloaliphatic alcohols, saturated or unsaturated fatty acids and alkylphenols, said derivatives containing 3 to 30 glycol ether groups and 8 to 20 carbon atoms in the (aliphatic) hydrocarbon moiety and 6 to 18 carbon atoms in the alkyl moiety of the alkylphenols.
The compositions may also contain further auxiliaries, such as stabilisers, antifoams, viscosity regulators, binders, tackifiers as well as fertilisers or other active ingredients for achieving spscial effects.
The agrochemical compositions usually contain 0.1 to 99 % by weight, preferably 0.1 to 95 % by weight, of a compound of formula I, 99.9 to 1 %
by weight, preferably 99.8 to 5 % by weight, of a solid or liquid adjuvant, and 0 to 25 % by weight, preferably 0.1 to~25 % by weight, of a surfactant, The following Examples serve to illustrate the invention without implying any limitation.
