Certain sulfonylamido-acetonitriles have been proposed for controlling plant-destructive fungi (for example in EP-A-176327 and EP-A-587110). The biological activity of those compounds is not, however, satisfactory in all aspects and for all needs of the agricultural practices in protecting crop plants.

Surprisingly, with developing the compounds of formula I a new type of microbiocides has been provided which satisfies to a greater extend the need for an agent for controlling phytopathogenic microorganisms on crop plants having a high level of activity, paired with long lasting effective protection.

The compounds of formula I and the respective starting materials may be obtained according to the processes of Schemes 1 to 7.

Scheme 1: wherein Ari, Ar2, a, b, c, W and Ri to R8, are defined as under formula 1, and A stands for a leaving group like an anhydride, i. e.-O-SO2-(CR1R2) a-X-Arl or-O-CO-C1-C4alkyl, but preferably for halogen, especially bromine or more preferably chlorine.

The compounds of formula I may be prepared by sulfonylation of an amino-acetonitrile of formula III with a sulfonyl-halide/anhydride of formula II wherein A is a leaving group, Suitable solvents for this reaction include ketones, such as acetone and methylethylketone, halogenated hydrocarbons such as chloroform, carbontetrachloride, dichloromethane, dichloro-ethane, aromatic hydrocarbons such as toluene or xylene, ethers such as t-butyl- methyl-ether, di-ethyl-ether, tetrahydrofuran and dioxane. The reaction is performed prefe- rentially in the presence of a base and a catalyst. Typical bases include tertiary amines such as trimethylamine, triethylamine, diisopropylethylamine, dimethyl-aniline, diazabi-cyclo- octane and N-methylmorpholine, aromatic amines such pyridine and quinoline as well as inorganic bases such as alkaline bicarbonates or-carbonates. Typical salts are for example sodium and potassium bicarbonate and sodium, potassium or cesium carbonate. Suitable catalysts such as N, N-dialkyl- or cyloalkyl-aminopyridines, like e. g. 4-N, N-dime-thylaminopy- ridine, may improve the yield.

The substituents R3 may be introduced into the final active ingredients when starting from the subgroup compounds of formula I wherein R3 is hydrogen, by reacting them e. g. with an alkylating agent R3-A'wherein A'designates a leaving group, preferably a halogen atom, e. g. bromo or chloro. Suitable alkylating agents thus include suitably substituted alkylhalides or alkyl-O-sulfonates, e. g. or alkoxy-alkylhalides. On the other hand, when introducing R3 with the starting compounds of formula 111, alkylating of the compounds of the subgroup of formula III, wherein R3 is hydrogen, may be achieved in a similar way by any commonly known alkylation method. Such alkylation prior to sulfonylation with a compound of formula 11, as alternative to converting R3 within the final products of formula 1, allows to introduce a wide variety of radicals R3 while leaving the choice to decide at which stage such optional conversion is preferably performed.

Cyano-amines of formula III may easily be prepared by the so-called Strecker-Synthesis according to Scheme 2 as described e. g. generically in any textbook on organic chemistry, or in a procedures disclosed in the patent literature (EP-A-953565-A; Nihon Noyaku or US 3,529, 019, Colgate-Palmolive) starting from the corresponding ketone of formula IV.

Scheme 2: wherein Ar2, b, c, W and R5 to R8 are defined as under formula I and L is a leaving group.

The reaction conditions correspond to the standard conditions for preparing amino- acetonitriles by treatment with ammonia and prussic acid.

For the preparation of the ketones of formula IV various methods are known from the literature. Preferably the synthesis is for example conducted in accordance with Scheme 3 by starting from the ketone of formula V, wherein R4, R5, R6 and b are defined as for for- mula I and L is a leaving group such as e. g. halogen, preferably chlorine, bromine or iodine or a sulfonyloxy group such as e. g. methylsulfonyloxy-, toluylsulfonyloxy-or trifluorome- thylsulfonyloxy-group, and reacting it with a compound of formula VI wherein Ar2, R7, R8 and c are defined as for formula I and W'is either an anionic radical species of W such as O-, S~, S (O) m- combined with an alkaline-or earthalkaline-metal cation as counterion, or is defined as W-H, e. g. as OH, SH, NHR3. In the latter case the reaction is generally carried out in the presence of a base such as alkaline-, earthalkaline-carbonates or hydrogencarbo- nates, e. g. sodium or potassium-carbonate, sodium or potassium-hydrogen-carbonate, cesium-carbonate or an agent capable of scavenging the formed acid.

Scheme 3: wherein Ar2, b, c, W and R4 to R8, are defined as under formula I and W'is either an anionic radical species of W such as O-, S-, S (O) r,,- combined with an alkaline-or earthalkaline-metal cation as counterion, or is defined as W-H, e. g. as OH, SH, NHR3.

As a typical alternative method of preparing the intermediate ketones of formula (IV) Scheme 3A highlights two of the various pathways.

Scheme 3A: OH o Ro \ O _R O / r - 0 0 (Xa) oxidation Rro O/+/\. (Rs) n (Rs) n (IVa) (VII) ou OU (Rlg) n (Xll) \ O °97 Ho<R4 +H Rio O Nu (R4) Ro \ O Rio OH L I' R4 \ [l oxidation \ O (XI) (Xb) I RQ (VIII) (Rs) n (R s) n (IVb) (non wherein R4, R'g, Rio and n are as defined under formula I and L is a leaving group, while Nu (R4) designates the nucleophilic form of R4, such as alkoxide or halides, especially iodides.

For the sake of simplicity in Scheme 3A the optionally substituted Ar2 is displayed as phenyl, but it is assumed that the entire variation of Ar2 as defined under formula I can be reacted similarly. According to Scheme 3A the selected intermediates of formula Va may be prepared by oxidizing the corresponding alcohols of formulae Xa and Xb. Advantageous oxidation procedures include the sulfur-based oxidation agents (in literature referred to as Swern-oxidation, Pfizer-Moffat and others), the metal based oxidation agents, hydrogen peroxide in the presence of metal catalysts such as Na2WO4 (c. f. e. g. R. Noyori, Bull. Chem.

Soc. Jpn. 1999, 72, 2287-2306) and others more.

The alcohols of formula Xa and Xb are available by ring-opening of an epoxide of formula VII or an epoxide of formula Vlil, e. g. epichlorhydrine with a phenol of formula Xll and in the latter case reacting the new intermediate epoxide of formula Xi again with a nucleophilic derivative of Nu (R4) such as alkoxide or halides, especially iodides.

The ring opening reaction may be performed in the presence of a catalyst. Suitable catalysts include bases, such as amines like pyridine, tri-ethanolamine and the like, or metal hydroxides and/or carbonates such as lithium hydroxide, cesium carbonate, potassium carbonate, potassium hydroxide, sodium hydroxide or metal hydrides, such as sodium hydride and lithium hydride or cesium fluoride as well as Lewis acids, such as tetrame- thylammonium chloride. Suitable solvents include alcohols, such as ethanol, isopropanol, tert-butanol and the like, ketones such as acetone and methyl ethyl ketone, and more polar solvents such as N, N-dimethylformamide, dimethylacetamide and nitriles, such as aceto- nitrile and propionitrile. The reaction temperature can vary within wide limits. It typically lies in the range of room temperature and the boiling point of the reaction mixture.

Preferable solvents for ring opening of the phenoxy-substituted epoxides of formula XI include polyalcohols such as ethyleneglycol, diethyleneglycol and triethyleneglycol, sulfoxides and sulfones such as dimethylsulfoxide and sulfolan as well as other polar solvents. A nucleophiles of special interest in this context is fluoride. Fluoride is typically used in form of potassium hydrogen difluorid (KHF2). The nucleophilicity of the fluoride ion may be enhanced by phase transfer reagents such as quaternary ammonium salts and phosphonium salts as well as complexing agents such as crown ethers. The reaction temperature lies between +100°C and the boiling point of the reaction mixture.

In general, epoxides of the general formulae VII or Vlil are commercially available or may be prepared according to published procedures such as reacting a phenol of the general formula XII with epichlorohydrine.

Many methods to prepare sulfonylation agent of formula 11 are known. General ways of preparing such compounds are e. g. described in Houben Weyl, Vol. E11, p 1067 ff (1985).

Another synthesis to prepare compounds of formula I is described in Scheme 4.

Scheme 4: wherein Ar, Ar2, a, b, c, X', W and R, to Ra are defined as under formula 1.

Compounds of formula XIII wherein Ar2, b, c, W and R3 to R8 are defined as under formula I and L is a leaving group such as e. g. halogen, preferably chlorine, bromine or iodine or a sulfonyloxy group such a e. g. methylsulfonyloxy-, toluylsulfonyloxy-or trifluoromethylsulfo- nyloxy-group, is coupled with a compound of formula XIV wherein X'is either an anionic radical species of X such as O-, S-, S (O) m combined with an alkaline-or earthalkaline- metal cation as counterion or is defined as X-H such as OH, SH, NHR3. In this case the reaction are generally carried out in the presence of a base such as alkaline-, earthalkaline- carbonates or hydrogencarbonates such e. g. sodium or potassium-carbonate, sodium or potassium-hydrogen-carbonate, cesium-carbonate or an agent capable of scavenging the formed acid.

The starting material of the chemical class of cyano-amines of formula III may also be prepared as described in Scheme 5.

Scheme 5: wherein Art, Ar2, b, c, W and R3 to R8 are defined as under formula I and symbol T designates a protecting group such as the well-acknowlegded tert-butyloxycarbonyl-or benzyloxycarbonyl-groups, often referred to as (BOC) -or (Z) -groups, and converting the compund of formula XVI into the desired formula III by cleaving the protective group T off.

Many methods are known in the chemical literature e. g.

The reaction conditions for the dihydratisation according to Scheme 5 may be adopted from known examples in the art.

In another preparatory synthesis pathway compounds of formula XXII, which is a subgroup of formula I, may be obtained according to Scheme 6.

The reaction pathway of Scheme 6 in the final step shows the ring opening reaction of the aziridine intermediate of formula XXI, which is in analogy to general methods described e. g. Tetrahedron, 52 (40), 13035-13050.

The reaction conditions are as e. g. described in the cited reference, using suitable inert solvents, including ketones, such as acetone and methylethylketone, halogenated hydro- carbons such as chloroform, carbontetrachloride, dichloromethane, dichloro-ethane, aroma- tic hydrocarbons such as toluene or xylene, ethers such as t-butyl-methyl-ether, di-ethyl- ether, tetrahydrofuran and dioxane. The reaction is performed preferentially in the presence of a base. Typical bases include tertiary amines such as trimethylamine, triethylamine, diiso- propylethylamine, dimethyl-aniline, diazabi-cyclooctane and N-methylmorpholine, aromatic amines such pyridine and quinoline as well as inorganic bases such as alkaline bicarbo- nates or-carbonates e. g. example sodium and potassium bicarbonate and sodium, potas- sium or cesium carbonate.

As also shown in Scheme 6 the aziridines of formula XXI may be prepared by a ring closing reaction, starting from alcohols of formula XX, by employing the so-called Mitsunobu reaction. Intermediate alcohols of formula XX are prepared in several step as outlined.

Ketones of formula XVII containing a protected hydroxy function in form of the group - O-Prot (Prot stands for the protective radical that temporarily replaces the H atom during a reaction sequence, but thereafter is reinstalled) desigating an easily cleavable ether group, like the tetrahydropyranyl-oxy group, are reacted as described above in a so-called Strecker-Synthesis. The ether groups, i. e. the tetrahydropyranyl-oxy group are easily prepared and cleaved as described e. g in Biorg. Med. Chem. Lett. 11 (2001), 18,2541-2543.

Enantiomeric mixtures of formula I may be separated into the enantiomers by chromatography on chiral stationary phase or by classical methodes of fractionated crystallization of diastereomeric salts of a suitable precursor and subsequent conversion into the desired products. Enantiomers or diastereoisomers may also be prepared by enantioselective or diastereoselective synthesis methods.

Alternatively the pure enantiomeric forms of the compounds of formula I may be obtained by the preparation method of Scheme 1 when using enantiomerically pure starting material of formula III*.

The preparation of the enantiomerically pure amines of formula III* may be achieved by sulfonylation as described in Scheme 7.

In analogy to the methods described in e. g. J. Org. Chem. 1999,64, 1278-84, ketones of formula (IV) may be treated with sterically fixed chiral sulfinamides, like th shown (R)- (+)-2-methyl-2-propanesulfinamide or (S)-(-)-2-methyl-2-propanesulfinamide to yield the chiral sulfinimides of formula XXIII.

Introducing the cyanide function by the so-called Strecker-type reaction selectively yields the pure diastereoisomers of formula XXIV. Preferably in this reaction step the sulfimides of formula XXIII are treated with a cyanating reagent, for example a di-alkoxy-aluminiumcya- nide like di-isopropoxy-aluminiumcyanide, in analogy to methods described in e. g. J. Org.

Chem. 2000,65, 8704-8708. Subsequent cleavage of the sulfinyl group by mineral acids like hydrogen chloride in the last step of the displayed sequence gives the enatomerically pure amines of formula III*.

For this invention it is understood that the preparation method of Scheme 1 encompasses as specific embodiments the preparation of the enantiomerically distinct compounds of formula I which are available when employing the intermediates III* made according to Scheme 7.

The compounds of formula I are oils or solids at room temperature and are distinguished by valuable microbiocidal properties. They can be used in the agricultural sector or related fields preventatively and curatively in the control of plant-destructive microorganisms. The compounds of formula I according to the invention are distinguished at low rates of concen- tration not only by outstanding microbiocidal, especially fungicidal, activity but also by being especially well tolerated by plants.

Surprisingly, it has now been found that the compounds of formula I have for practical pur- poses a very advantageous microbiocidal spectrum in the control of phytopathogenic micro- organisms, especially fungi. They possess very advantageous curative and preventive pro- perties and are used in the protection of numerous crop plants. With the compounds of for- mula I it is possible to inhibit or destroy phytopathogenic microorganisms that occur on vari- ous crops of useful plants or on parts of such plants (fruit, blossom, leaves, stems, tubers, roots), while parts of the plants which grow later also remain protected, for example, against phytopathogenic fungi.

The novel compounds of formula I prove to be effective against specific genera of the fun- gus class Fungi imperfecti (e. g. Cercospora), Basidiomycetes (e. g. Puccinia) and Ascomy- cetes (e. g. Erysiphe and Venturia) and especially against Oomycetes (e. g. Plasmopara, Pe- ronospora, Pythium and Phytophthora). They therefore represent in plant protection a valu- able addition to the compositions for controlling phytopathogenic fungi. The compounds of formula I can also be used as dressings for protecting seed (fruit, tubers, grains) and plant cuttings from fungal infections and against phytopathogenic fungi that occur in the soil.

The invention relates also to compositions comprising compounds of formula I as active ingredient, especially plant-protecting compositions, and to the use thereof in the agri- cultural sector or related fields.

In addition, the present invention includes the preparation of those compositions, wherein the active ingredient is homogeneously mixed with one or more of the substances or groups of substances described herein. Included is a method of treating plants characterized by the application of the novel compounds of formula I or of the novel compositions.

Target crops to be protected within the scope of this invention comprise, for example, the following species of plants : cereals (wheat, barley, rye, oats, rice, maize, sorghum and related species); beet (sugar beet and fodder beet); pomes, stone fruit and soft fruit (apples, pears, plums, peaches, almonds, cherries, strawberries, raspberries and black- berries); leguminous plants (beans, lentils, peas, soybeans); oil plants (rape, mustard, poppy, olives, sunflowers, coconut, castor oil plants, cocoa beans, groundnuts); cucurbi- taceae (marrows, cucumbers, melons); fibre plants (cotton, flax, hemp, jute); citrus fruit (oranges, lemons, grapefruit, mandarins); vegetables (spinach, lettuce, asparagus, cabbages, carrots, onions, tomatoes, potatoes, paprika); lauraceae (avocado, cinnamon, camphor) and plants such as tobacco, nuts, coffee, sugar cane, tea, pepper, vines, hops, bananas and natural rubber plants, and also ornamentals.

The compounds of formula I are normally used in the form of compositions and can be applied to the area or plant to be treated simultaneously or in succession with other active ingredients. Those other active ingredients may be fertilisers, micronutrient donors or other preparations that influence plant growth. It is also possible to use selective herbicides or insecticides, fungicides, bactericides, nematicides, molluscicides or mixtures of several of those preparations, if desired together with further carriers, surfactants or other application- promoting adjuvants customarily employed in formulation technology.

The compounds of formula I can be mixed with other fungicides, resulting in some cases in unexpected synergistic enhancement of the biological activities. Such mixtures are not limited to two active ingredients (one of formula I and one of the list of other fungicides), but to the contrary many comprise more than one active ingredient of the component of formula I and more than one other fungicide. Mixing components which are particularly suited for this purpose include e. g. azoles, such as azaconazole, bitertanol, bromuconazole, cypro- conazole, difenoconazole, diniconazole, epoxiconazole, fenbuconazole, fluquinconazole, flusilazole, flutriafol, hexaconazole, imazalil, S-imazalil, imibenconazole, ipconazole, met- conazole, myclobutanil, oxpoconazole, pefurazoate, penconazole, pyrifenox, prochloraz, propiconazole, prothioconazole, simeconazole, tebuconazole, tetraconazole, triadimefon, triadimenol, triflumizole and triticonazole ; pyrimidinyl carbinoles, such as ancymidol, fena- rimol and nuarimol ; 2-amino-pyrimidines, such as bupirimate, dimethirimol and ethirimol ; morpholines, such as dodemorph, fenpropidine, fenpropimorph, spiroxamine and tride- morph; anilinopyrimidines, such as cyprodinil, mepanipyrim and pyrimethanil ; pyrroles, such as fenpiclonil and fludioxonil ; phenylamides, such as benalaxyl, furalaxyl, metalaxyl, R-metalaxyl, ofurace and oxadixyl ; benzimidazoles, such as benomyl, carbendazim, deba- carb, fuberidazole and thiabendazole ; dicarboximides, such as chlozolinate, dichlozoline, iprodione, myclozoline, procymidone and vinclozoline ; carboxamides, such as carboxin, fenfuram, flutolanil, furametpyr, mepronil, oxycarboxin and thifluzamide ; guanidines, such as guazatine, dodine and iminoctadine; strobilurines, such as azoxystrobin, dimoxystrobin (SSF-129), fluoxastrobin, kresoxim-methyl, metominostrobin, orysastrobin, picoxystrobin, pyraclostrobin and trifloxystrobin ; dithiocarbamates, such as ferbam, mancozeb, maneb, metiram, propineb, thiram, zineb and ziram; N-halomethylthiotetrahydrophthalimides, such as captafol, captan, dichlofluanid, fluoromides, folpet and tolyfluanid ; Copper-compounds, such as Bordeaux mixture, copper hydroxide, copper oxychloride, copper sulfate, cuprous oxide, mancopper and oxine-copper; nitrophenol-derivatives, such as dinocap and nitrothal- isopropyl ; organo-P-derivatives, such as edifenphos, iprobenphos, isoprothiolane, phosdi- phen, pyrazophos and tolclofos-methyl ; various others, such as acibenzolar-S-methyl, anila- zine, benthiavalicarb, blasticidin-S, boscalid, chinomethionate, chloroneb, chlorothalonil, IKF-916 (proposed name cyazofamid), cyflufenamid, cymoxanil, dichlone, diclomezine, dicloran, diethofencarb, dimethomorph, ethaboxam, fenoxanil, SYP-LI90 (proposed name: flumorph), dithianon, etridiazole, famoxadone, fenamidone, fentin, ferimzone, fluazinam, flusulfamide, fenhexamid, fosetyl-aluminium, hymexazol, iprovalicarb, kasugamycin, methasulfocarb, metrafenone, pencycuron, phthalide, picobenzamid, polyoxins, probena- zole, propamocarb, pyroquilon, proquinazid, quinoxyfen, quintozene, silthiofam, sulfur, triazoxide, triadinil, tricyclazole, triforine, validamycin, or zoxamide.

In the above mentioned mixtures, the mixture ratio of the active ingredients is so selected that it reaches optional control of the phytopathogenic microorganism on the host plants.

This ratio is in general between 100: 1 and 1: 100, more preferably between 10: 1 and 1: 10 of a compound of formula I vis-a-vis the second fungicide. The mixtures may not only comprise one of the listed combinational active ingredients, but may comprise more than one additional active ingredients selected from that specified group, thus forming for example 3-way-or even 4-way-mixtures.

Suitable carriers and surfactants may be solid or liquid and correspond to the substances ordinarily employed in formulation technology, such as e. g. natural or regenerated mineral substances, solvents, dispersants, wetting agents, tackifiers, thickeners, binders or fertilisers. Such carriers and additives are described, for example, in WO 95/30651.

A preferred method of applying a compound of formula 1, or an agrochemical composition comprising at least one of those compounds, is application to the foliage (foliar application), the frequency and the rate of application depending upon the risk of infestation by the pathogen in question. The compounds of formula I may also be applied to seed grains (coating) either by impregnating the grains with a liquid formulation of the active ingredient or by coating them with a solid formulation.

The compounds of formula I are used in unmodified form or, preferably, together with the adjuvants conventionally employed in formulation technology, and are for that purpose advantageously formulated in known manner e. g. into emulsifiable concentrates, coatable pastes, directly sprayable or dilutable solutions, dilute emulsions, wettable powders, soluble powders, dusts, granules, and by encapsulation 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 object- ives and the prevailing circumstances.

Advantageous rates of application are normally from 1 g to 2 kg of active ingredient (a. i.) per hectare (ha), preferably from 10 g to 1 kg a. i. /ha, especially from 25 g to 750 g a. i./ha.

When used as seed dressings, rates of from 0.001 g to 5.0 g of active ingredient per kg of seed are advantageously used.

The formulations, i. e. the compositions, preparations or mixtures comprising the com- pound (s) (active ingredient (s) ) of formula I and, where appropriate, a solid or liquid adjuvant, are prepared in known manner, e. g. by homogeneously mixing and/or grinding the active ingredient with extenders, e. g. solvents, solid carriers and, where appropriate, surface-active compounds (surfactants).

Further surfactants customarily used in formulation technology will be known to the person skilled in the art or can be found in the relevant technical literature.

The agrochemical compositions usually comprise 0.01 to 99 % by weight, preferably 0.1 to 95 % by weight, of a compound of formula 1, 99.99 to 1 % by weight, preferably 99.9 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.

Whereas commercial products will preferably be formulated as concentrates, the end user will normally employ dilute formulations.

The compositions may also comprise further ingredients, such as stabilisers, antifoams, viscosity regulators, binders and tackifiers, as well as fertilisers or other active ingredients for obtaining special effects.

Biological Examples D-1 : Action against Plasmopara viticola on vines a) Residual-protective action Vine seedlings are sprayed at the 4-to 5-leaf stage with a spray mixture (0.02 % active ingredient) prepared from a wettable powder formulation of the test compound. After 24 hours, the treated plants are infected with a sporangia suspension of the fungus. Fungus infestation is evaluated after incubation for 6 days at 95-100 % relative humidity and +20°C. b) Residual-curative action Vine seedlings are infected at the 4-to 5-leaf stage with a sporangia suspension of the fungus. After incubation for 24 hours in a humidity chamber at 95-100 % relative humidity and +20°C, the infected plants are dried and sprayed with a spray mixture (0.02 % active ingredient) prepared from a wettable powder formulation of the test compound. After the spray coating has dried, the treated plants are placed in the humidity chamber again.

Fungus infestation is evaluated 6 days after infection.

Compounds of Tables 1 exhibit a good fungicidal action against Plasmopara viticola on vines. Compounds No. 040,052, 059,071, 091,101, 102,104, 105, 157,186, 197,220, 228,229, 271,288, 289,331, 332,378, 381,391, 421,422, 452,453, 469,479, 489,499, 512,513, 514,517, 464,568, 607,659 and 662 at 200 ppm inhibit fungal infestations in both tests D-1 a) and D-1b) by 80-100 %. At the same time untreated plants showed pathogen attack of 60-100 %.

D-2: Action against Phytophthora on tomato plants a) Residual-protective action After a cultivation period of 3 weeks, tomato plants are sprayed with a spray mixture (0. 02 % active ingredient) prepared from a wettable powder formulation of the test compound. After 48 hours, the treated plants are infected with a sporangia suspension of the fungus. Fungus infestation is evaluated after incubation of the infected plants for 5 days at 90-100 % relative humidity and +20°C. b) Systemic action After a cultivation period of 3 weeks, tomato plants are watered with a spray mixture (0.02 % active ingredient based on the volume of the soil) prepared from a wettable powder formula- tion of the test compound. Care is taken that the spray mixture does not come into contact with the parts of the plants that are above the ground. After 96 hours, the treated plants are infected with a sporangia suspension of the fungus. Fungus infestation is evaluated after incubation of the infected plants for 4 days at 90-100 % relative humidity and +20°C.
