The present invention relates to the use of 4-aminopyrimidines of the formula I
in which the substituents are as defined below:
Moreover, the invention relates to novel 4-aminopyrimidines, to processes for preparing these compounds and to compositions comprising them.
EP-A 407 899 and EP-A 12 54 903 propose fungicidally and/or microbicidally active aminopyrimidines in a general manner. However, in many cases their activity against phytopathogenic harmful fungi is unsatisfactory. Based on this, it is an object of the present invention to provide compounds having improved activity and/or a wider activity spectrum.
We have found that this object is achieved by the compounds defined at the outset. Furthermore, we have found processes and intermediates for their preparation, compositions comprising them and methods for controlling harmful fungi using the compounds I.
The compounds of the formula I differ from those in the abovementioned publications by the specific embodiment of the substituents in positions 4, 5 and 6 of the pyrimidine ring.
Compared to the known fungicidal compounds, the compounds of the formula I are more effective against harmful fungi.
The novel compounds of the formula I can be obtained by different routes.
Advantageously, the compounds of the formula I are obtained by converting substituted β-ketoesters of the formula II with thiourea of the formula III to give 2-thio-4-hydroxy-pyrimidines of the formula IV. The variables in formulae II and IV are as defined formula I and the group R in formula II is C1-C4-alkyl; for practical reasons, preference is given here to methyl, ethyl or propyl.
The reaction of the substituted β-ketoesters of the formula II with thiourea of the formula III can be carried out in the presence or absence of solvents. It is advantageous to use solvents to which the starting materials are substantially inert and in which they are completely or partially soluble.
Suitable solvents are in particular alcohols, such as ethanol, propanols, butanols, glycols or glycol monoethers, diethylene glycols or their monoethers, aromatic hydrocarbons, such as toluene, benzene or mesitylene, amides, such as dimethylformamide, diethylformamide, dibutylformamide, N,N-dimethylacetamide, lower alkanoic acids, such as formic acid, acetic acid, propionic acid, or bases, such as alkali metal and alkaline earth metal hydroxides, alkali metal and alkaline earth metal oxides, alkali metal and alkaline earth metal hydrides, alkali metal amides, alkali metal and alkaline earth metal carbonates and also alkali metal bicarbonates, organometallic compounds, in particular alkali metal alkyls, alkylmagnesium halides and also alkali metal and alkaline earth metal alkoxides and dimethoxymagnesium, moreover organic bases, for example tertiary amines, such as trimethylamine, triethylamine, triisopropylethylamine, tributylamine and N-methylpiperidine, N-methylmorpholine, pyridine, substituted pyridines, such as collidine, lutidine and 4-dimethylaminopyridine, and also bicyclic amines and mixtures of these solvents with water.
Suitable catalysts are bases as mentioned above or acids such as sulfonic acids or mineral acids. With particular preference, the reaction is carried out in the absence of a solvent or in chlorobenzene, xylene, dimethyl sulfoxide or N-methylpyrrolidone.
Particularly preferred bases are tertiary amines, such as triisopropylamine, tributylamine, N-methylmorpholine or N-methylpiperidine. The temperatures are from 50 to 300° C., preferably from 50 to 180° C., if the reaction is carried out in solution [cf. EP-A 770 615; Adv. Het. Chem. 57 (1993), 81ff].
The bases are generally employed in catalytic amounts; however, they can also be employed in equimolar amounts, in excess or, if appropriate, as solvent.
The β-ketoesters of the formula II can be prepared as described in Organic Synthesis Coll. Vol. 1, p. 248, and/or they are commercially available.
Using alkylating agents D-X, such as alkyl halides, preferably methyl chloride or methyl bromide, or dimethyl sulfate or methyl methanesulfonate, the 2-thio-4-hydroxypyrimidines of the formula IV are converted into the thioethers V. The reaction can be carried out in water or else in a dipolar aprotic solvent, such as, for example, N,N-dimethylformamide [cf. U.S. Pat. No. 5,250,689], it is advantageously carried out in the presence of a base, such as, for example, KOH, NaOH, NaHCO3 and Na2CO3 or pyridine. The reaction temperature is preferably 10-60° C.
In the formulae V and VI, D is as defined in formula I.
Using halogenating agents, in particular chlorinating agents or brominating agents, the compounds of the formula V are converted into compounds of the formula VI in which Hal is chlorine or bromine, in particular chlorine. Suitable chlorinating agents for the conversion of the hydroxyl compounds V into the compounds VI are, for example, POCl3, PCl3/Cl2 or PCl5, or mixtures of these reagents. The reaction can be carried out in excess chlorinating agent (POCl3) or in an inert solvent, such as, for example, acetonitrile, toluene, chlorobenzene or 1,2-dichloroethane. The reaction is preferably carried out in POCl3.
This reaction is usually carried out between 10 and 180° C. For practical reasons, the reaction temperature usually corresponds to the boiling point of the chlorinating agent (POCl3) or solvent employed. The process is advantageously carried out with addition of catalytic or substoichiometric amounts of N,N-dimethylformamide or nitrogen bases, such as, for example, N,N-dimethylaniline.
Using ammonia in inert solvents, the halogenation product VI is then, at 100° C. to 200° C., converted into the 4-aminopyrimidines I in which R3 is a group S-D (formula I.1). The reaction is preferably carried out using a 1- to 10-molar excess of ammonia under a pressure of from 1 to 100 bar.
Thioethers I.1 in which R3 is a group S-D can be oxidized to give the corresponding sulfoxides or sulfones I.1. The oxidation is preferably carried out at from 10 to 50° C. in the presence of protic or aproptic solvents [cf.: B. Kor. Chem. Soc., Vol. 16, pp. 489-492 (1995); Z. Chem., Vol. 17, p. 63 (1977)]. Suitable oxidizing agents are, for example, hydrogen peroxide or 3-chloroperbenzoic acid. Hydrogen peroxide and peracids of organic carboxylic acids have been found to be particularly suitable oxidizing agents. The oxidation can also be carried out using selenium dioxide [cf.: ref. WO 02/88127].
The compounds of the formula I.2 are useful intermediates for preparing further compounds I. For practical reasons, particular preference is given to compounds I.2 in which D is C1-C4-alkyl, in particular methyl. In formula I.2, the substituents R1 and R2 are as defined in formula I.
For preparing compounds of the formula I in which R3 is cyano or a group attached via a heteroatom, hydroxyl, mercapto, azido, alkoxy, alkenyloxy, alkynyloxy, haloalkoxy, alkylthio, alkenylthio, alkynylthio, haloalkylthio, —ON═CRaRb, —NRaN═CRaRb, NRaRb, —NRaNRaRb or —NORa, it is advantageous to use sulfones of the formula I.2 as starting materials.
The sulfones of the formula I.2 are reacted with compounds of the formula VII under basic conditions. For practical reasons, it is alternatively possible to employ directly the alkali metal, alkaline earth metal or ammonium salt of the compound VII.
In the case of sufficiently nucleophilic reagents, this reaction is carried out under the conditions of nucleophilic substitution, usually at from 0 to 200° C., preferably from 10 to 150° C. in the presence of a dipolar aprotic solvent, such as N,N-dimethylformamide, tetrahydrofuran or acetonitrile [cf. DE-A 39 01 084; Chimia, Vol. 50, pp. 525-530 (1996); Khim. Geterotsikl. Soedin, Vol. 12, pp. 1696-1697 (1998)].
In general, the components are employed in approximately stoichiometric amounts. However, it may be advantageous to use an excess of the nucleophile of the formula R3—H.
In general, the reaction is carried out in the presence of a base which may be employed in equimolar amounts or else in excess. Suitable bases are alkali metal carbonates and bicarbonates, for example Na2CO3 and NaHCO3, nitrogen bases, such as triethylamine, tributylamine and pyridine, alkali metal alkoxides, such as sodium ethoxide or potassium tert-butoxide, alkali metal amides, such as NaNH2, or else alkali metal hydrides, such as LiH or NaH.
Suitable solvents are halogenated hydrocarbons, ethers, such as diethyl ether, diisopropyl ether, tert-butyl methyl ether, 1,2-dimethoxyethane, dioxane, anisole and tetrahydrofuran, and also dimethyl sulfoxide, dimethylformamide and dimethylacetamide. Particular preference is given to ethanol, dichloromethane, acetonitrile and tetrahydrofuran. It is also possible to use mixtures of the solvents mentioned.
Suitable bases are, in general, inorganic compounds, such as alkali metal and alkaline earth metal hydroxides, such as lithium hydroxide, sodium hydroxide, potassium hydroxide and calcium hydroxide, alkali metal and alkaline earth metal hydrides, such as lithium hydride, sodium hydride, potassium hydride and calcium hydride, alkali metal and alkaline earth metal carbonates, such as lithium carbonate, potassium carbonate and calcium carbonate. The bases are generally employed in catalytic amounts; however, they can also be used in excess.
The starting materials are generally reacted with one another in equimolar amounts. In terms of yield, it may be advantageous to employ an up to 10-fold, in particular up to 3-fold, excess of VII, based on I.2.
The compounds I in which R3 is cyano (formula I.3) are useful intermediates for preparing further compounds I.
Compounds of the formula I in which R3 is hydrogen, alkyl, alkenyl, alkynyl or haloalkyl are advantageously obtained from β-ketoesters of the formula II by reaction with amidines of the formula IIIa.
If, as amidine component IIIa, guanidine (R3═NH2) is reacted with the β-ketoester II, 2-aminopyrimidines are obtained. Using generally customary alkylation and acylation processes, it is thus possible to synthesize, in a simple manner, pyrimidines according to the invention having, in the 2-position, a radical attached via nitrogen.
Analogously to the reaction sequence described above, the compounds Va are initially halogenated to give the 4-halopyrimidines VIa, which compounds VIa are reacted with ammonia under the conditions described for the compounds VI to give the corresponding compounds of the formula I.
An advantageous route for preparing the pyrimidines I in which R3 is a group attached via nitrogen uses β-ketoesters II as starting materials. Reaction with urea IIIb gives the compounds Vb which can be halogenated, preferably chlorinated, to give VIb.
Using halogenating agents, in particular chlorinating agents or brominating agents, hydroxypyrimidines of the formula Vb are converted into halogen compounds of the formula VIb in which Hal is chlorine or bromine, in particular chlorine. Suitable chlorinating agents are, for example, POCl3, PCl3/Cl2 or PCl5, or mixtures of these reagents. The reaction can be carried out in excess chlorinating agent (POCl3) or in an inert solvent, such as, for example, acetonitrile, toluene, chlorobenzene or 1,2-dichloroethane. Preference is given to carrying out the reaction in POCl3 [cf. J. Chem. Soc. (1943) p. 383; Helv. Chim. Acta (1981) Vol. 64, pp. 113-152].
This reaction is usually carried out between 10 and 180° C. For practical reasons, the reaction temperature usually corresponds to the boiling point of the chlorinating agent (POCl3) or solvent employed. The process is advantageously carried out with addition of catalytic or substoichiometric amounts of N,N-dimethylformamide or nitrogen bases, such as, for example, N,N-dimethylaniline.
By reaction with ammonia, VIb gives 2,4-diaminopyrimidines of the formula I in which R3 is NH2.
This reaction is usually carried out using ammonia in inerten solvents at from 100° C. to 200° C. The reaction is preferably carried out using a 1- to 10-molar excess of ammonia under a pressure of from 1 to 100 bar.
Using generally known alkylation or acylation methods, the 2-amino group in formula I can be converted into other groups R3 which are attached via nitrogen. Preferred alkylating or acylating agents are the alkylating agents D-X, such as dialkyl sulfate, alkyl halides, carbonyl chlorides, carboxylic anhydrides [cf.: Chem. Ber. Vol. 87, p. 1769 (1954)]
In the case of strong nucleophiles R3—H of the formula VII, the introduction of the substituent R3 into the nitrile of the formula I.3 is carried out under the conditions of nucleophilic substitution. Moreover, the introduction can also be carried out under transition metal catalysis, such as, for example, under the Suzuki coupling reaction conditions. This reaction is advantageously carried out under the conditions known from J. Chem. Soc. (1943) p. 388 and J. Org. Chem. (1952) Vol. 17, p. 1320.
Alternatively, compounds of the formula I can be obtained by reacting substituted acyl cyanides of the formula VIII in which R1 and R2 are as defined for formula I with thiourea of the formula III.
The reaction can be carried out in the presence or absence of solvents. It is advantageous to use solvents which are substantially inert toward the reactants and in which the reactants are completely or partially soluble. Suitable solvents are in particular alcohols, such as ethanol, propanols, butanols, glycols or glycol monoethers, diethylene glycols or monoethers thereof, aromatic hydrocarbons, such as toluene, benzene or mesitylene, amides, such as dimethylformamide, diethylformamide, dibutylformamide, N,N-dimethylacetamide, lower alkanoic acids, such as formic acid, acetic acid, propionic acid, or bases, as mentioned above, and mixtures of these solvents with water. The reaction temperatures are between 50 and 300° C., preferably from 50 to 150° C., if the reaction is carried out in solution.
Some of the substituted alkyl cyanides of the formula VIII required for preparing the compounds I are known, or they can be prepared by known methods from alkyl cyanides and carboxylic acid esters using strong bases, for example alkali metal hydrides, alkali metal alkoxides, alkali metal amides or metal alkyls (cf.: J. Amer. Chem. Soc. Vol. 73, (1951), p. 3766).
The further conversion of these thio compounds via alkylation and oxidation to give sulfoxides and sulfones which can be reated further with compounds R3—H of the formula VII has already been described further above.
Alternatively, compounds of the formula I in which R3 is NRaCN can also be prepared from 5,6-dialkyl-7-aminotriazolopyrimidines of the formula IX which are reacted under basic conditions with alkylating agents of the formula VIIa.
In formula VIIIa, X is a nucleophilically exchangeable group, such as a halogen atom, in particular an iodine atom. The reaction of VIIa with IX is usually carried out at temperatures of from −78° C. to 100° C., preferably from 10° C. to 80° C., in an inert organic solvent in the presence of a base [cf. WO 01/96314].
Compounds of the formula IX are known in a general manner from EP-A 141 317.
Compounds of the formula I in which R3 is a derivatized carboxylic acid group, such as C(═O)Rc, —C(═O)NRaRb, —C(═NORc)NRaRb, —C(═NNRaRb)Rc or —C(═NORa)Rc, are advantageously obtained from compounds of the formula I.3.
Compounds of the formula I in which R3 is —C(═O)NRaRb or —C(═NORc)NRaRb are obtainable from compounds of the formula I.3 by hydrolysis under acidic or basic conditions, to give the carboxylic acids of the formula I (where R3═COOH), and amidation with amines HNRaRb. The hydrolysis is usually carried out in inert polar solvents, such as water or alcohols, preferably using inorganic bases, such as alkali metal or alkaline earth metal hydroxides, in particular NaOH.
These reactions are advantageously carried out under the conditions known from Chem. and Pharm. Bull. 1982, Vol. 30, N12, p. 4314.
Amides of the formula I (where R3═CONH2) afford, by oximation with substituted hydroxylamines H2N—ORc under basic conditions, the compounds of the formula I in which R3 is —C(═NORc)NRaRb [cf. U.S. Pat. No. 4,876,252]. The substituted hydroxylamines can be employed as free base or, preferably, in the form of their acid addition salts. For practical reasons, the halides, such as the chlorides or the sulfates, are particularly suitable.
Alternatively, the amidoximes of the formula I in which R3 is —C(═NORc)NH2 can also be obtained form the corresponding nitriles of the formula I.3 by reaction with hydroxylamine and subsequent alkylation. This reaction is advantageously carried out under the conditions known from DE-A 198 37 794.
Compounds of the formula I in which R3 is —C(═O)Rc can be obtained from the corresponding nitriles of the formula I.3 by reaction with Grignard reagents Rc—Mg-Hal, where Hal is a halogen atom, in particular chlorine or bromine.
This reaction is advantageously carried out under the conditions known from J. Heterocycl. Chem. 1994, Vol. 31(4), p. 1041.
Compounds of the formula I in which R3 is —C(═NNRaRb)Rc can be obtained via compounds I (where R3═C(O)Rc) which are reacted with hydrazines H2NNRaRb, preferably under the conditions known from J. Org. Chem. 1966, Vol. 31, p. 677.
Compounds of the formula I in which R3 is —C(═NORa)Rc can be obtained via oximation of compounds I (where R3═C(O)Rc). The oximation is carried out as described above.
Compounds of the formula I in which R1 is C1-C14-haloalkyl, C1-C12-haloalkoxy-C1-C12-alkyl, C1-C12-alkoxy-C1-C12-haloalkyl, C2-C12-haloalkenyl or C2-C12-haloalkynyl can be obtained by halogenation of corresponding halogen-free pyrimidines of the formula I, they are referred to as compounds I′. In formula I′, R1′ is a halogen-free group R1. In formula I″, R1″ is a halogenated group R1:
The halogenation is usually carried out at temperatures of from 0° C. to 200° C., preferably from 20° C. to 110° C., in an inert organic solvent in the presence of a free-radical initiator (for example dibenzoyl peroxide or azobisisobutyronitrile or under UV irradiation using, for example, an Hg vapor lamp) or an acid [cf. Synthetic Reagents, Vol. 2, pp. 1-63, Wiley Publishers, New York (1974)].
The reaction partners are generally reacted with one another in equimolar amounts. In terms of yield, it may be advantageous to employ an excess of halogenating agent, based on I′.
Suitable halogenating agents are, for example, elemental halogens (for example Cl2, Br2, I2), N-bromosuccinimide, N-chlorosuccinimide oder dibromodimethylhydrantoin. The halogenating agents are generally employed in equimolar amounts, in excess or, if appropriate, as solvent.
The reaction mixtures are worked up in a customary manner, for example by mixing with water, separating the phases and, if appropriate, chromatographic purification of the crude products. Some of the intermediates and end products are obtained in the form of colorless or slightly brownish viscous oils which can be purified or freed from volatile components under reduced pressure and at moderately elevated temperature. If the intermediates and end products are obtained as solids, purification can also be carried out by recrystallization or digestion.
If individual compounds I cannot be obtained by the routes described above, they can be prepared by derivatization of other compounds I.
If the synthesis yields mixtures of isomers, a separation is generally not necessarily required, however, since in some cases the individual isomers can be interconverted during work-up for use or during application (for example under the action of light, acids or bases). Such conversions may also take place after use, for example in the treatment of plants in the treated plants, or in the harmful fungus to be controlled.

The following are examples of formulations: 1. Products for dilution with water
10 parts by weight of the active compounds are dissolved in 90 parts by weight of water or in a water-soluble solvent. As an alternative, wetting agents or other auxiliaries are added. The active compound dissolves upon dilution with water. In this way, a formulation having a content of 10% by weight of active compound is obtained.
20 parts by weight of the active compounds are dissolved in 70 parts by weight of cyclohexanone with addition of 10 parts by weight of a dispersant, for example polyvinylpyrrolidone. Dilution with water gives a dispersion. The active compound content is 20% by weight
15 parts by weight of the active compounds are dissolved in 75 parts by weight of xylene with addition of calcium dodecylbenzenesulfonate and castor oil ethoxylate (in each case 5 parts by weight). Dilution with water gives an emulsion. The formulation has an active compound content of 15% by weight.
25 parts by weight of the active compounds are dissolved in 35 parts by weight of xylene with addition of calcium dodecylbenzenesulfonate and castor oil ethoxylate (in each case 5 parts by weight). This mixture is introduced into 30 parts by weight of water by means of an emulsifying machine (e.g. Ultraturrax) and made into a homogeneous emulsion. Dilution with water gives an emulsion. The formulation has an active compound content of 25% by weight.
In an agitated ball mill, 20 parts by weight of the active compounds are comminuted with addition of 10 parts by weight of dispersants and wetting agents and 70 parts by weight of water or an organic solvent to give a fine active compound suspension. Dilution with water gives a stable suspension of the active compound. The active compound content in the formulation is 20% by weight.

In a ball mill, 20 parts by weight of the active compounds, 10 parts by weight of dispersant, 1 part by weight of gelling agent and 70 parts by weight of water or an organic solvent are ground to give a fine suspension. On dilution with water, a stable suspension having an active compound content of 20% by weight is obtained.
5 parts by weight of the active compounds are ground finely and mixed intimately with 95 parts by weight of finely divided kaolin. This gives a dustable product having an active compound content of 5% by weight.
0.5 part by weight of the active compounds is ground finely and associated with 99.5 parts by weight of carriers. Current methods are extrusion, spray-drying or the fluidized bed. This gives granules to be applied undiluted having an active compound content of 0.5% by weight.
10 parts by weight of the active compounds are dissolved in 90 parts by weight of an organic solvent, for example xylene. This gives a product to be applied undiluted having an active compound content of 10% by weight.
For seed treatment, use is usually made of water-soluble concentrates (LS), suspensions (FS), dustable powders (DS), water-dispersible and water-soluble powders (WS, SS), emulsions (ES), emulsifiable concentrates (EC) and gel formulations (GF). These formulations can be applied to the seed in undiluted form or, preferably, diluted. Application can be carried out prior to sowing.
The active compounds can be used as such, in the form of their formulations or the use forms prepared therefrom, for example in the form of directly sprayable solutions, powders, suspensions or dispersions, emulsions, oil dispersions, pastes, dustable products, materials for spreading, or granules, by means of spraying, atomizing, dusting, spreading or pouring. The use forms depend entirely on the intended purposes; the intention is to ensure in each case the finest possible distribution of the active compounds according to the invention.
Aqueous use forms can be prepared from emulsion concentrates, pastes or wettable powders (sprayable powders, oil dispersions) by adding water. To prepare emulsions, pastes or oil dispersions, the substances, as such or dissolved in an oil or solvent, can be homogenized in water by means of a wetter, tackifier, dispersant or emulsifier. Alternatively, it is possible to prepare concentrates composed of active substance, wetter, tackifier, dispersant or emulsifier and, if appropriate, solvent or oil, and such concentrates are suitable for dilution with water.
The active compound concentrations in the ready-to-use preparations can be varied within relatively wide ranges. In general, they are from 0.0001 to 10%, preferably from 0.01 to 1%.
The active compounds may also be used successfully in the ultra-low-volume process (ULV), by which it is possible to apply formulations comprising over 95% by weight of active compound, or even to apply the active compound without additives.
Various types of oils, wetters, adjuvants, herbicides, fungicides, other pesticides, or bactericides may be added to the active compounds, if appropriate not until immediately prior to use (tank mix). These agents can be admixed with the agents according to the invention in a weight ratio of 1:100 to 100:1, preferably 1:10 to 10:1.
Suitable adjuvants in this sense are in particular: organically modified polysiloxanes, for example Break Thru S 240®; alcohol alkoxylates, for example Atplus 245®, Atplus MBA 1303®, Plurafac LF 300® and Lutensol ON 30®; EO/PO block polymers, for example Pluronic RPE 2035® and Genapol B®; alcohol ethoxylates, for example Lutensol XP 80®; and sodium dioctylsulfosuccinate, for example Leophen RA®.
The compositions according to the invention can, in the use form as fungicides, also be present together with other active compounds, e.g. with herbicides, insecticides, growth regulators, fungicides or else with fertilizers. Mixing the compounds I or the compositions comprising them in the application form as fungicides with other active compounds, in particular fungicides, it is in many cases possible to broaden the activity spectrum or to prevent the development of resistance. In many cases, synergistic effects are obtained.

Examples of the Action Against Harmful Fungi
The fungicidal action of the compounds of the formula I was demonstrated by the following experiments:
The active compounds were prepared as a stock solution comprising 25 mg of active compound which was made up to 10 ml using a mixture of acetone and/or DMSO and the emulsifier Uniperol® EL (wetting agent having emulsifying and dispersing action based on ethoxylated alkylphenols) in a volume ratio of solvent:emulsifier of 99:1. The mixture was then made up to 100 ml with water. This stock solution was diluted with the solvent/emulsifier/water mixture described to the concentration of active compounds stated below.
Leaves of potted tomato plants were sprayed to runoff point with an aqueous suspension having the concentration of active compounds stated below. The next day, the leaves were infected with an aqueous sporangia suspension of Phytophthora infestans. The plants were then placed in a water-vapor-saturated chamber at temperatures between 18 and 20° C. After 6 days, the late blight on the untreated, but infected control plants had developed to such an extent that the infection could be determined visually in %.
In this test, the plants which had been treated with 250 ppm of the compounds I-2, I-4, I-35, I-41 to 46, I-48, I-51 to 55, I-57 to 60, I-62 to 65, I-68, I-71, I-73, I-74, I-79, I-88 or I-91 showed at most 20% infection, whereas the untreated plants were 85-90% infected.
50 μl of the required concentration of active compounds were pipetted onto a microtiter plate (MTP). The plate was then inoculated with 50 μl of an aqueous sporangia suspension of Phytophthora infestans. The plates were placed in a water-vapor-saturated chamber at temperatures of 18° C. On the seventh day after the inoculation, the absorption of the MTPs was measured at 405 nm using an absorption photometer. Using the measured parameters, the growth of the control and the blank value, the relative growth in % of the pathogens in the individual active compounds was determined.
In this test, at 125 ppm of the compound I-3 or I-4, the relative growth found was at most 11%.
50 μl of the required concentration of active compounds were pipetted onto a microtiter plate (MTP). The plate was then inoculated with 50 μl of an aqueous sporangia suspension of Pyricularia oryzae. The plates were placed in a water-vapor-saturated chamber at temperatures of 18° C. On the seventh day after the inoculation, the absorption of the MTPs was measured at 405 nm using an absorption photometer. Using the measured parameters, the growth of the control and the blank value, the relative growth in % of the pathogens in the individual active compounds was determined. In this test, at 125 ppm of the compound I-3 growth was inhibited completely.
Leaves of potted vines were sprayed to runoff point with an aqueous suspension having the concentration of active compounds stated below. To be able to assess the persistency of the substances, the plants were, after the spray coating had dried on, placed in a greenhouse for 7 days. Only then were the leaves inoculated with an aqueous zoospore suspension of Plasmopara viticola. The vines were then initially placed in a water vapor-saturated chamber at 24° C. for 24 hours and then in a greenhouse at temperatures between 20 and 30° C. for 5 days. After this time, the plants were once more placed in a humid chamber for 16 hours to accelerate the eruption of sporangiospores. The extent of the development of the infection on the undersides of the leaves was then determined visually.
In this test, the plants which had been treated with 500 ppm of the compounds I-1, I-2, I-4, I-10 to 14, I-16, I-17, I-20, I-22, I-23, I-26, I-27, I-28, I-33, I-35 to 53, I-55 to 66, I-68, I-70, I-72 to I-79, bzw. I-80 showed an infection of at most 15%, whereas the untreated plants were 75% infected.
