Surprisingly, it has been found that compounds of the formula I can be used as crop protection agents having fungicidal and/or herbicidal action. They are suitable for treating plants, for example for controlling harmful fungi in useful plants (fungicidal action) or for controlling undesirable plant growth in the case of harmful plants (herbicidal action).




Compounds of the formula I can be prepared analogously to the processes known from the literature (for example J. Am. Chem. Soc. 39 (1908), 63; DD 156663). The starting materials are either known from the literature or they can be prepared analogously to methods known from the literature, or they are commercially available.




The present invention furthermore provides crop protection compositions which comprise the compounds of the formula I, with the exception of the compounds described in DD 156,663 as plant-growth-regulating agents. What is meant in this context are in particular crop protection compositions which comprise the compounds I, with the proviso that




a) if A is an unsubstituted phenyl group and R

is hydrogen or alkyl, R


1


is not unsubstituted phenyl or halogen-substituted phenyl;




b) if R


3


is hydrogen, A is not 2-nitrophenyl or 2-aminophenyl.




The present invention furthermore provides novel compounds of the formula I as described above, except for the compounds described in WO 95/35283, EP 0 466 640, DD 156663 and DE 2008692 and the individual compounds mentioned above under a)-e). What is meant in this context are in particular those compounds of the formula I, with the proviso that




a) if A is an unsubstituted phenyl group and R


3


is hydrogen or alkyl, R


1


is not unsubstituted phenyl or halogen-substituted phenyl;




b) if R


3


is hydrogen, A is not 2-nitrophenyl or 2-aminophenyl;




c) if R


3


is hydrogen, R


1


is hydrogen, alkyl or alkylaryl, A is not phenyl which is substituted directly or indirectly by an aryl group.




In the definition of the different radicals in the formula I, the given terms, either on their own (such as, for example, C

-“alkyl”) or as parts of or in combination with other composite chemical groups (such as, for example, C


1


-C


6


-halo-“alkyl”, alkoxy-C

Depending on the substitution pattern, the compounds of the formula I can contain one or more chiral centers, in which case they are present as enantiomers or mixtures of diastereomers. The invention provides both the pure enantiomers or diastereomers and their mixtures. The ratios can vary, depending on the groups. The mixtures can, if appropriate, be separated by customary methods. The compounds I can be used both as pure isomers and as isomer mixtures.




The compounds of the formula I can also be present in the form of their agriculturally useful salt, the type of salt usually being immaterial. in general, the salts of those cations or the acid addition salts of those acids are suitable whose cations and anions, respectively , do not negatively affect the herbicidal or fungicidal action of the compounds I.




Suitable cations are, in particular, ions of the alkali metals, preferably lithium, sodium and potassium, of the alkaline earth metals, preferably calcium and magnesium, and of the transition metals, preferably manganese, copper, zinc and iron, and also ammonium, where, if desired, one to four hydrogen atoms may be replaced by C

-cycloalkyl, in particular cyclopropyl.




If A or R


1


is phenyl, the phenyl ring may be substituted by one to five of the abovementioned radicals, which may be in the 2-, 3- or 4-position. Th e phenyl ring is preferably mono- or disubstituted. Preferred substituents are: halogen, alkyl, alkoxy, nitro, cyano, haloalkyl, phenyl.




In the case of monosubstituted phenyl rings, suitable substituents are in particular the following groups: halogen, such as, for example, fluorine, chlorine; alkyl, such as, for example, methyl; alkoxy, such as, for example, methoxy; nitro; haloalkyl, such as, for example, trifluoromethyl; or cyano. For this purpose, for example the following groups are suitable: 4-halophenyl, 4-alkylphenyl, 4-alkoxyphenyl, 4-nitrophenyl, 4-cyanophenyl, 4-trifluoromethylphenyl, 2-halophenyl, 2-alkylphenyl, 2-alkoxyphenyl, 2-nitrophenyl, 2-cyanophenyl, 2-trifluoromethylphenyl, 3-halophenyl, 3-alkylphenyl, 3-alkoxyphenyl, 3-nitrophenyl, 3-cyanophenyl, 3-trifluoromethylphenyl.




In the case of disubstituted phenyl rings, suitable substituents are in particular the following groups, where the substituents may be identical or different: halogen, such as, for example, chlorine; or alkyl, such as, for example, methyl. For this purpose, for example the following groups are suitable: 2,3-dihalophenyl, 2,4-dihalophenyl, 2,5-dihalophenyl, 2,6-dihalophenyl, 3,4-dihalophenyl, 3,5-dihalophenyl, 2,3-dimethylphenyl, 2,4-dimethylphenyl, 2,5-dimethylphenyl, 2,6-dimethylphenyl, 3,4-dimethylphenyl, or 3,5-dimethylphenyl.

The compounds of the formula I can be prepared analogously to the process as described in the literature (cf. DD 156663, J.Am.Chem.Soc. 39 (1908), 63). The synthesis is carried out, for example, by the following standard process, where the phenyl rings in formula II or III may be unsubstituted or substituted:











X is a suitable leaving group, such as, for example, halogen or alkoxy.




The cyanocarboxylic acid derivatives of the formula II can be prepared by processes known from the literature (cf. Org. Synthesis, Collect Vol IV, 1963, p. 461 ff.). The phenylamines of the formula III are either commercially available, or they can also be prepared by processes known from the literature.




The compounds of the formula I are suitable for use as active compounds for preparing crop protection compositions. For the purpose of the present invention, crop protection compositions are generally understood as being mixtures of active compounds of the formula I with additives or auxiliaries which make possible the use of the mixtures in agriculture or gardening and the application of these compositions onto areas free from crops or for treating plants. The crop protection compositions can preferably be employed as herbicides and/or fungicides.




The plants are usually sprayed or dusted with the active compounds or the crop protection compositions, or the seeds of the plants are treated with the active compounds.




The compounds of the formula I and their agriculturally useful salts are suitable, both in the form of stereoisomeric mixtures and in the form of the pure stereoisomers, especially as herbicides. The herbicidal compositions comprising the compounds of the formula I control plant growth on non-crop areas very efficiently, especially at high rates of application. They act against broad-leaved weeds and grass weeds in crops such as wheat, rice, maize, soybean and cotton without causing any significant damage to the crop plants. This effect is mainly observed at low rates of application.




Depending on the particular application method, the compounds of the formula I or the compositions comprising them can additionally be employed in a further number of crop plants for eliminating undesirable plants. Examples of suitable crops are the following:

In addition, the compounds of the formula I can also be used in crops which tolerate the action of herbicides owing to breeding, including genetic engineering methods.




The compounds of the formula I or the compositions comprising them can be used, for example, in the form of ready-to-spray aqueous solutions, powders, suspensions, also highly-concentrated aqueous, oily or other suspensions or dispersions, emulsions, oil dispersions, pastes, dusts, materials for broadcasting, or granules, by means of spraying, atomizing, dusting, broadcasting or watering. The use forms depend on the intended aims; in any case, they should ensure the finest possible distribution of the active compounds according to the invention.




The herbicidal compositions comprise a herbicidally effective amount of at least one compound of the formula I or an agriculturally useful salt of I and auxiliaries which are customary for formulating crop protection agents.




Suitable inert auxiliaries are essentially: mineral oil fractions of medium to high boiling point, such as kerosene and diesel oil, furthermore coal tar oils and oils of vegetable or animal origin, aliphatic, cyclic and aromatic hydrocarbons, for example paraffins, tetrahydronaphthalene, alkylated naphthalenes and their derivatives, alkylated benzenes and their derivatives, alcohols, such as methanol, ethanol, propanol, butanol, cyclohexanol, ketones such as cyclohexanone, or strongly polar solvents, for example amines such as N-methylpyrrolidone, or water.




Aqueous use forms can be prepared from emulsion concentrates, suspensions, pastes, wettable powders or water-dispersible granules by adding water. To prepare emulsions, pastes or oil dispersions, the compounds of the formula I, either as such or dissolved in an oil or solvent, can be homogenized in water by means of a wetting agent, tackifier, dispersant or emulsifier. Alternatively, it is possible to prepare concentrates comprising active compound, wetting agent, tackifier, dispersant or emulsifier and, if desired, solvent or oil, which are suitable for dilution with water.




Suitable surfactants are the alkali metal salts, alkaline earth metal salts and ammonium salts of aromatic sulfonic acids, for example ligno-, phenol-, naphthalene- and dibutylnapthalenesulfonic acid, and of fatty acids, alkyl- and alkylarylsulfonates, alkyl sulfates, lauryl ether sulfates and fatty alcohol sulfates, and salts of sulfated hexa-, hepta- and octadecanols, and also of fatty alcohol glycol ethers, condensates or sulfonated naphthalene and its derivatives with formaldehyde, condensates of naphthalene, or of the naphthalene sulfonic acids with phenol and formaldehyde, polyoxyethylene octyl phenol ether, ethoxylated isooctyl-, octyl- or nonylphenol, alkylphenol or tributylphenyl polyglycol ether, alkylaryl polyether alcohols, isotridecyl alcohol, fatty alcohol ethylene oxide condensates, ethoxylated castor oil, polyoxyethylene alkyl ether or polyoxypropylene alkyl ethers, lauryl alcohol polyglycol ether acetate, sorbitol esters, lignin-sulfite waste liquors or methylcellulose.




Powders, materials for broadcasting and dusts can be prepared by mixing or jointly grinding the active substances together with a solid carrier.




Granules, for example coated granules, impregnated granules and homogeneous granules, can be prepared by binding the active compounds to solid carriers. Solid carriers are mineral earth, such as silicas, silica gels, silicates, talc, kaolin, limestone, lime, chalk, bowl, loess, clay, dolomite, diatomaceous earth, calcium sulfate, magnesium sulfate, magnesium oxide, ground synthetic materials, fertilizers, such as ammonium sulfate, ammonium phosphate, ammonium nitrate, ureas, and products of vegetable origin, such as cereal meal, tree bark meal, wood meal and nutshell meal, cellulose powders or other solid carriers.




The concentrations of the compounds of the formula I in the ready-to-use preparations can be varied within wide ranges. In general, the formulations comprise from 0.001 to 98% by weight, preferably 0.01 to 95% by weight of at least one active compound. The active compounds are employed in a purity of from 90% to 100%, preferably 95% to 100% (according to NMR spectrum).




The compounds I according to the invention can be formulated, for example, as follows:




a) 20 parts by weight of a compound I are dissolved in a mixture composed of 80 parts by weight of alkylated benzene, 10 parts by weight of the adduct of 8 to 10 mol of ethylene oxide to 1 mol of oleic acid N-monoethanolamide, 5 parts by weight of calcium dodecylbenzenesulfonate and 5 parts by weight of the adduct of 40 mol of ethylene oxide to 1 mol of castor oil. Pouring the solution into 100 000 parts by weight of water and finely distributing it therein gives an aqueous dispersion which comprises 0.02% by weight of the active compound.




b) 20 parts by weight of a compound I are dissolved in a mixture composed of 40 parts by weight of cyclohexanone, 30 parts by weight is isobutanol, 20 parts by weight of the adduct of 7 mol of ethylene oxide to 1 mol of isooctylphenol and 10 parts by weight of the adduct of 40 mol of ethylene oxide to 1 mol of castor oil. Pouring the solution into 100 000 parts by weight of water and finely distributing it therein gives an aqueous dispersion which comprises 0.02% by weight of the active compound.




c) 20 parts by weight of a compound I are dissolved in a mixture composed of 25 parts by weight of cyclohexanone, 65 parts by weight of a mineral oil fraction of boiling point 210 to 2800C and 10 parts by weight of the adduct of 40 mol of ethylene oxide to 1 mol of castor oil. Pouring the solution into 100 000 parts by weight of water and finely distributing it therein gives an aqueous dispersion which comprises 0.02% by weight of the active compound.




d) 20 parts by weight of a compound I are mixed thoroughly with 3 parts by weight of sodium diisobutylnaphthalenesulfonate, 17 parts by weight of the sodium salt of a lignosulfonic acid from a sulfite waste liquor and 60 parts by weight of pulverulent silica gel, and the mixture is ground in a hammer mill. Finely distributing the mixture in 20000 parts by weight of water gives a spray mixture which comprises 0.1% by weight of the active compound.




e) 3 parts by weight of a compound I are mixed with 97 parts by weight of finely divided kaolin. This gives a dust which comprises 3% by weight of active compound.




f) 20 parts by weight of a compound I are mixed intimately with 2 parts by weight of calcium dodecylbenzenesulfonate, 8 parts by weight of fatty alcohol polyglycol ether, 2 parts by weight of the sodium salt of a phenol/urea/formaldehyde condensate and 68 parts by weight of a paraffinic mineral oil. This gives a stable oily dispersion.




g) 1 part by weight of a compound I is dissolved in a mixture composed of 70 parts by weight of cyclohexanone, 20 parts by weight of ethoxylated isooctylphenol and 10 parts by weight of ethoxylated castor oil. This gives a stable emulsion concentrate.




h) 1 part by weight of a compound I is dissolved in a mixture composed of 80 parts by weight of cyclohexanone and 20 parts by weight of Wettol® EM 31 (nonionic emulsifier based on ethoxylated castor oil). This gives a stable emulsion concentrate.




The active compounds of the formula I or the herbicidal compositions can be applied pre- or post-emergence. If the active compounds are less well tolerated by certain crop plants, application techniques may be used in which the herbicidal compositions are sprayed, with the aid of the spraying equipment, in such a way that they come into as little contact as possible, if any, with the leaves of the sensitive crop plants, while the active compounds reach the leaves of undesirable plants growing underneath, or the bare soil surface (post-directed, lay-by).




To widen the spectrum of action and to achieve synergistic effects, the compounds of the formula I may be mixed with a large number of representatives of other herbicidal or growth-regulating groups of active compounds and then applied concomitantly. Suitable components for mixtures are, for example, 1,2,4-thiadiazoles, 1,3,4-thiadiazoles, amides, aminophosphoric acid and its derivatives, aminotriazoles, anilides, aryloxy/hetaryloxyalkanoic acid and its derivatives, benzoic acid and its derivatives, benzothiadiazinones, 2-(aroyl/hetaroyl)-1,3-cyclohexanediones, hetaryl aryl ketones, benzylisoxazolidinones, meta-CF


3


-phenyl derivatives, carbamates, quinoline carboxylic acid and its derivatives, chloroacetanilides, cyclohexenenone oxime ether derivatives, diazines, dichloropropionic acid and its derivatives, dihydrobenzofurans, dihydrofuran-3-ones, dinitroanilines, dinitrophenols, diphenyl ethers, dipyridyls, halocarboxylic acids and their derivatives, ureas, 3-phenyluracils, imidazoles, imidazolinones, N-phenyl-3,4,5,6-tetrahydrophthalimides, oxadiazoles, oxiranes, phenols, aryloxy- and heteroaryloxyphenoxypropionic esters, phenyl acetic acid and its derivatives, phenylpropionic acid and its derivatives, pyrazoles, phenylpyrazoles, pyridazines, pyridinecarboxylic acid and its derivatives, pyrimidyl ethers, sulfonamides, sulfonyl ureas, triazines, triazinones, triazolinones, triazolecarboxamides and uracils.




It may furthermore be advantageous to apply the compounds of the formula I, alone or in combination with other herbicides, in the form of a mixture with other crop protection agents, for example together with agents for controlling pests of phytopathogenic fungi or bacteria. Also of interest is the miscibility with mineral salt solutions, which are employed for treating nutritional and trace element deficiencies. Non-phytotoxic oils and oil concentrates may also be added.




Depending on the control target, the season, the target plant and the growth stage, the active compound application rates are from 0.001 to 3.0, preferably from 0.01 to 1.0, kg of active substance (a. S.)/ha.




Compounds of the formula I also have fungicidal action. They are distinguished, in particular, by excellent action against a broad spectrum of phytopathogenic fungi, especially from the classes of the Ascomycetes, Deuteromycetes, Phycomycetes and Basidiomycetes. Some of them act systemically, and they can therefore also be employed as folia- and soil-acting fungicides.




They are of particular importance for controlling a large number of fungi in various crop plants, such as wheat, rye, barley, oats, rice, maize, turf, cotton, soybean, coffee, sugarcane, grapevines, fruits and ornamental plants and vegetables, such as cucumbers, beans and cucurbits, and in the seeds of these plants.




The compounds are applied by treating the fungi or the seeds, plants, materials or the soil to be protected against fungal attack with a fungicidally active amount of the active compounds. Application is carried out before or after the infection of the materials, plants or seeds by the fungi.




The novel compounds are particularly suitable for controlling the following plant diseases:


Erysiphe graminis


(powdery mildew) in cereals,


Erysiphe cichoracearum


and


Sphaerotheca fuliginea


in cucurbits,


Podosphaera leucotricha


in apples,


Uncinula necator


in grapevines, Puccinia species in cereals, Rhizoctonia species in cotton and turf, Ustilago species in cereals and sugarcane,


Venturia inaequalis


(scab) in apples, Helminthosporium species in cereals,


Septoria nodorum


in wheat,


Botrytis cinerea


(gray mold) in strawberries, grapevines, ornamental plants and vegetables,


Cercospora arachidicola


in groundnuts,


Pseudocercosporella herpotrichoides


in wheat, barley,


Pyricularia oryzae


in rice, Phytophthora infestans in potatoes and tomatoes, Fusarium and Verticillium species in a variety of plants,


Plasmopara viticola


in grapevines, Alternaria species in vegetables and fruit.




The active compounds of the formula I can also be employed in the protection of materials (wood protection), for example against


Paecilomyces variotii.






The fungicidal compositions generally comprise between 0.1 and 95, preferably between 0.5 and 90, % by weight of active compound.




Depending on the nature of the desired effect, the application rates are between 0.025 and 2, preferably from 0.1 to 1, kg of active compound per ha.




In the treatment of seed, amounts of active compound of generally from 0.001 to 50, preferably from 0.01 to 10, g per kilogram of seed are required.




In the use form as fungicides, the compositions according to the invention can also be present together with other active compounds, for example with herbicides, insecticides, growth regulators, fungicides or else with fertilizers.




When the compounds are mixed with fungicides, in many cases this results in a broadening of the fungicidal activity spectrum.




The following list of fungicides which can be applied jointly with the compounds according to the invention is meant to illustrate the possible combinations, without imposing a limitation: fungicides from the active compound group of the sulfur compounds, dithibcarbamates and their derivatives; nitro derivatives; heterocyclic substances, such as, for example, imidazoline derivatives, triazoles, triazine derivatives, quinoxaline derivatives, benzimidazole derivatives, thiadiazole derivatives, etc.; or strobilurins.











The following working examples illustrate the invention in more detail:




EXAMPLE 1




N-(3-chlorophenyl)-2-cyano-2-phenylacetamide (Compound No. 2 from Table 1) 3 g (0.016 mol) of ethyl phenylcyanoacetate and 2 g (0.016 mol) of 3-chloroaniline are heated undiluted at 130° C. for 5 hours. The mixture is subsequently taken up in 100 ml of dichloromethane and extracted three times with 10% strength hydrochloric acid. The organic phase is separated off, dried and concentrated. The resulting residue is taken up in 30 ml of dichloromethane, and 200 ml of petroleum ether are added. The resulting crystalline precipitate is filtered off with suction, washed with petroleum ether and dried. Yield 38%; m.p. 123° C.




EXAMPLE 2




Herbicidal Action




The herbicidal action of the compounds according to the invention is investigated using the representative test model below. The effect of the test substances on the growth of duck weed is determined by the following method:




The duct weed


Lemna paucicostata


was grown under sterile conditions and 250 ml glass vessels containing 100 ml of inorganic nutrient solution and supplemented with 1% sucrose, as described by Grossmann et al., Pesticide Science 35, (1992), 283-289. At the beginning of the test, 150 μl of a solution of active compound in acetone (stock solution: 100-fold concentrated) were pipetted into Petri dishes (diameter 6 cm, height 1.5 cm; Greiner, Frickenhausen) containing 15 ml of nutrient solution. (without added sucrose). Only the solvent component of the active compound solution was added to the nutrient solution for the control tests. Then, 4 Lemna plants were introduced into each dish, the dishes were covered with lids and incubated under permanent light conditions at 25° C. After 8-10 days, the increase in leaf area was determined using an imaging apparatus (Imago, Compulog Computer Syst., Böblingen) as growth parameter, and this was used to calculate the growth inhibition as a percentage relative to the control.




The results of the tests can be seen from the table which follows. The herbicidal effect of the compounds according to the invention is demonstrated by the potent inhibition of the growth of Lemna.
