This application is a continuation of application Ser. No. 880,990, filed July 2, 1986, now abandoned. 
    
    
     BACKGROUND OF THE INVENTION 
     This invention relates to alpha-aryl-alpha-phenyl-ethyl-1H-1,2,4-triazole-1-propanenitriles and their use in controlling phytopathogenic fungi. The phenethyl and aryl moieties may be substituted or unsubstituted. 
     Miller et al., U.S. Pat. No. 4,366,165 discloses 1- and 4-arylcyanoalkyl-1,2,4-triazoles and their use against phytopathogenic fungi. However, neither the phenethyl triazoles of the present invention nor the benzyl triazoles were made by Miller et al. Therefore, they failed to recognize the particular class of compounds of the present invention or that this class has a particularly high degree of fungicidal activity. The phenethyl triazoles of the present invention are not only effective against wheat powdery mildew, wheat stem rust and wheat leaf rust but are significantly superior to the benzyl triazoles and phenyl triazoles against barley helminthosporium, rice blast and peanut early leafspot. 
     European Patent Application 52,424, published May 26, 1982, also generically discloses the compounds of the present invention. However, none of the present compounds were made. In fact, none of the examples of the 52,424 application have a cyano group attached to the quaternary carbon, but include either a hydroxy, methoxy, butoxy or allyloxy group. The three phenethyl triazole compounds which were made and disclosed in the 52,424 application are 4,4-dimethyl-3-hydroxy-3-(1,2,4-triazol-1-yl)methyl-1-(halogen substituted phenyl)-pentanes. 
     Published German patent application no. 3,216,301 discloses the fungicidal activity of alkoxytriazolepropionitriles. 
     European application 63,099 discloses the use of chloromethyltriazole to produce a 1H-1,2,4-triazol-1-yl-methylphosphonium salt. 
     Published British patent application 2,119,374 discloses a process to make alpha-(alkoxy, alkenoxy, alkynoxy or phenylalkoxy)-alpha-aryl-triazolylmethylacetonitrile compounds.

     The structures of the Comparative compounds are set forth below. ##STR14## 
     The triazoles of the present invention can be prepared by conventional synthesis routes. For example, the triazoles may be prepared by nucleophilic displacement of the alpha-(bromomethyl)-alpha-(2-phenylethyl)-phenylacetonitrile (VIII) by a salt, preferably an alkali metal salt, of the triazole, generally about 1 to about 3 equivalents. This reaction can be run either neat or, preferably, in an appropriate solvent such as dimethylsulfoxide (DMSO), N,N-dimethylformamide (DMF), toluene or xylene at a temperature from about 0° C. to about 150° C., preferably from about 25° C. to about 100° C. The compound VIII is prepared by bromomethylation of the alpha-2-phenylethyl-phenylacetonitrile (IX) by methylenebromide (generally about 1.1 to about 2 equivalents) under basic conditions, e.g., sodium or potassium hydroxide, sodium or potassium hydride, potassium methoxide and potassium-t-butoxide (generally about 1.1 to about 2 equivalents) preferably with the use of a solvent such as DMSO with sodium hydroxide or DMF with the hydrides and oxides, at a temperature from about 0° C. to about 150° C., preferably from about  25° C. to about 100° C. The compound IX can be prepared by phase transfer alkylation of the appropriately substituted benzylcyanides (X) with generally about 1 to about 2 equivalents of a 2-phenylethylmethanesulfonate (mesylate) or p-toluenesulfonate (tosylate) in the presence of a strong base, e.g., 50% (w/w) sodium hydroxide, and a catalyst, e.g., tetrabutylammonium bromide (TBABr). Compound IX can also be prepared by alkylation of the appropriately substituted benzylcyanide with about 1 to 2 equivalents of a 2-phenylethylhalide in the presence of a strong base such as metal hydrides, e.g. sodium or potassium hydride, using DMF or DMF/toluene as the solvent. Both the benzylcyanides and the alkyl halides can be readily prepared by techniques known from the literature. This synthesis scheme is shown below: ##STR15## 
     The phenethyl triazole (I) can be prepared directly from the phenylethyl-phenylacetonitrile (IX) in one step by the reaction with a halomethyltriazole (XI) in a solvent such as DMF. Two equivalents of a strong base such as sodium hydride or potassium hydride are used. This synthesis scheme is shown below: ##STR16## 
     This reaction is not limited to the preparation of the triazoles of the present invention. The reaction can also be used to prepare compounds having a quaternary carbon bonded to an aryl group, a cyano group and a triazole group such as disclosed in U.S. Pat. No. 4,366,165 and British patent application 2,119,374. The method disclosed in the prior art requires the additional step of preparing an aryl-cyano-(halomethyl, alkylsulphonyloxymethyl or arylsulphonyloxymethyl) compound which is reacted with a triazole or an alkali metal triazole derivative. This extra step is eliminated by the process of the present invention. 
     The acid addition salts of the triazoles of this invention can be prepared by standard techniques well-known in the art. For example, the triazole of formula (I) can be dissolved in an appropriate solvent such as diethyl ether, tetrahydrofuran, ethanol, methanol and the like or combinations thereof and treated with an equivalent or excess amount of a mineral or organic acid which may or may not be dissolved in an appropriate solvent, the mixture is then either cooled or evaporated to give the salt which can either be used as such or recrystallized from an appropriate solvent or combination of appropriate solvents. 
     The metal salt complexes of the above triazoles of this invention can be prepared by adding dropwise, with stirring, a stoichiometric amount of a metal salt dissolved in an appropriate solvent or combination of solvents to a solution of the triazole of formula (I) dissolved in a similarly appropriate solvent or combination of solvents. The reaction mixture is briefly stirred and the solvent is removed under reduced pressure to give the metal salt complex of the respective triazoles of formula (II). 
     The metal salt complexes can also be prepared by mixing stoichiometric or excess amounts of the metal salt and a triazole of formula (I) in the desired amount of solvent containing the appropriate adjuvants just prior to spraying the plants. Adjuvants that may be included in this &#34;in situ&#34; preparation may be detergents, emulsifiers, wetting agents, spreading agents, dispersing agents, stickers, adhesives, and the like which are used in agricultural applications. 
     Solvents that can be utilized in these procedures include any polar solvent, e.g., water, methanol, ethanol, isopropanol or ethylene glycol and any aprotic dipolar solvent, e.g., dimethylsulfoxide, acetonitrile, dimethylformamide, nitromethane or acetone. 
     The metal salt cations that can be used in these procedures can be selected from the group consisting of calcium, magnesium, manganese, copper, nickel, zinc, iron, cobalt, tin, cadmium, mercury, chromium, lead, barium and the like. 
     Any appropriate anion, e.g., chloride, bromide, iodide, sulfate, bisulfate, phosphate, nitrate, perchlorate, carbonate, bicarbonate, hydrosulfide, hydroxide, acetate, oxalate, malate, citrate and the like may be utilized as the counterion in the metal salt. 
     The compounds of this invention possess an asymmetric carbon atom and thus exist as racemic mixtures. The d and l enantiomorphs in these racemic mixtures can be separated via standard techniques such as fractional crystallization with d-tartaric acid, l-tartaric acid, l-quinic acid and the like followed by basification and extraction of the d or l enantiomorph free base. 
     The enantiomorphs, acid addition salts and metal salt complexes of the present invention are useful as agricultural fungicides and as such can be applied to various loci such as the seed, the soil or the foliage. For such purposes these compounds can be used in the technical or pure form as prepared, as solutions or as formulations. The compounds are usually taken up in a carrier or are formulated so as to render them suitable for subsequent dissemination as fungicides. For example, these chemical agents can be formulated as wettable powders, emulsifiable concentrates, dusts, granular formulations, aerosols, or flowable emulsion concentrates. In such formulations, the compounds are extended with a liquid or solid carrier and, when desired, suitable surfactants are incorporated. 
     It is usually desirable, particularly in the case of foliar spray formulations, to include adjuvants, such as wetting agents, spreading agents, dispersing agents, stickers, adhesives and the like in accordance with agricultural practices. Such adjuvants commonly used in the art can be found in the John W. McCutcheon, Inc. publication &#34;Detergents and Emulsifiers, Annual.&#34; 
     In general, the compounds of this invention can be dissolved in certain solvents such as acetone, methanol, ethanol, dimethylformamide or dimethyl sulfoxide and such solutions can be extended with water. The concentrations of the solution can vary from about 1% to about 90% with a preferred range being from about 5% to about 50%. 
     For the preparation of emulsifiable concentrates, the compound can be dissolved in suitable organic solvents, or a mixture of solvents, together with an emulsifying agent which permits dispersion of the fungicide in water. The concentration of the active ingredient in emulsifiable concentrates is usually from about 10% to about 90% and in flowable emulsion concentrates, this can be as high as about 75%. 
     Wettable powders suitable for spraying, can be prepared by admixing the compound with a dispersing agent and a finely divided solid, such as clays, inorganic silicates and carbonates, and silicas, and optionally incorporating wetting agents and sticking agents in such mixtures. The concentration of active ingredients in such formulations is usually in the range of from about 20% to about 98%, preferably from about 40% to about 75%. A typical wettable powder is made by blending 50 parts of alpha-[2-(4-chlorophenyl)ethyl]-alpha-(2-methoxyphenyl)-1H-1,2,4-triazole-1-propanenitrile, 45 parts of a synthetic precipitated hydrated silicon dioxide sold under the trademark Hi-Sil®, 1 part sodium lauryl sulfate and 5 parts of sodium lignosulfonate. In another preparation a kaolin type (Barden) clay is used in place of the Hi-Sil in the above wettable powder, and in another such preparation 25% of the Hi-Sil is replaced with a synthetic sodium aluminate sold under the trademark Zeolex® 7. 
     Dusts are prepared by mixing the triazoles, enantiomorphs, salts and complexes thereof with finely divided inert solids which can be organic or inorganic in nature. Materials useful for this purpose include botanical flours, silicas, silicates, carbonates and clays. One convenient method of preparing a dust is to dilute a wettable powder with a finely divided carrier. Dust concentrates containing from about 20% to about 80% of the active ingredient are commonly made and are subsequently diluted to from about 1% to about 10% use concentration. 
     The enantiomorphs, salts and complexes thereof can be applied as fungicidal sprays by methods commonly employed, such as conventional high-gallonage hydraulic sprays, low-gallonage sprays, air-blast spray, aerial sprays and dusts. The dilution and rate of application can be readily determined by one in the art depending upon the type of equipment used, the desired method, timing and frequency of applications, plants to be treated and diseases to be controlled. Generally, however, the fungicidal compounds of the present invention will be applied in an amount of from about 0.01 to about 20 pounds of active ingredient per acre when applied foliarly or to the soil. 
     As a seed protectant, the amount of the compound coated on the seeds is usually from about 0.05 to about 4 ounces of active ingredient per hundred pounds of seed and preferably from 0.1 to about 1 ounce per hundred pounds of seed. As a soil fungicide the compounds can be incorporated in the soil or applied to its surface usually at a rate of from about 0.05 to about 20 pounds, preferably from about 0.02 to about 10 pounds and more preferably from about 0.1 to about 3 pounds of active ingredient per acre. As a foliar fungicide, the compounds are usually applied to growing plants at a rate of from about 0.01 to about 10 pounds, preferably from about 0.02 to about 5 and more preferably from about 0.03 to about 1 pound of active ingredient per acre.

     In summary, the substituted benzylcyanide was synthesized to the alpha-phenyl-alpha-(2-phenylethyl)-1H-1,2,4-triazole-1-propanenitrile in three steps. The benzylcyanide was alkylated in the first step by one of six methods. The alkylated phenylacetonitrile was bromomethylated in the second step by one of four methods. The alkylated triazole propanenitrile was synthesized from the alkylated phenylacetonitrile bromide by nucleophilic displacement with potassium triazole in the third step. In the third step the potassium triazole was either previously prepared and added to the bromide or equal parts of potassium hydroxide, triazole and DMSO was added to an equivalent amount of toluene, heated to 100°-120° C. for 2 hours to distill off the toluene and drive off the azeotropic water and the bromide added to the freshly prepared potassium triazole. In a third method the potassium triazole was prepared in situ by the reaction of potassium carbonate and triazole in a MEK or DMSO solvent. 
     A two step procedure can be used to prepare the alpha-phenyl-alpha-(2-phenylethyl)-1H-1,2,4-triazole-1-propanenitrile. The first step is the same as for the three step procedure. However the product of step 1 is coupled via a base with chloromethyltriazole.HCl in DMF. At least two equivalents of base is employed. The anion is generated at room temperature then the solid HCl salt is added. The second equivalent liberates the salt to the free base, chloromethyl triazole, which reacts with the anion. The base can be hydroxide, alkoxide or hydride. NaOH or KOH can be employed however NaH is preferred on an experimental scale. For less acidic intermediates where the anion is more difficult to form KH is preferred. 
     A similar procedure using chloromethyl triazole.HCl is to liberate the salt to the free base prior to addition. This can be done with NaOH in CH 2  Cl 2 , then the solvent removed and the addition done with DMF using NaH as the base or DMSO with NaOH as the base. 
     The halogenated phenethyl triazoles may be prepared from the corresponding phenethyl triazoles by the reaction with N-chlorosuccinimide (NCS) or N-bromosuccinimide (NBS) in the presence of a catalyst or initiator such as benzoyl peroxide. The phenethyl triazole is dissolved in an inert solvent such as carbon tetrachloride and 1 or 2 equivalents of the halogenating agent is used. 
     The halogenated triazoles can be transformed into the ethenyl compound by base elimination using a metal hydroxide or alkoxide. Typical bases include sodium hydroxide, sodium methoxide and potassium tert-butoxide.

The reaction was cooled to 10° C. and 50 gms (0.63 mole, 1.2 eq.) of 50% NaOH was added dropwise over 30 minutes. The reaction exothermed to 35° C. and was cooled to 10° C. The reaction was stirred for 48 hours at room temperature and gas liquid chromatography indicated 60% product and 40% benzyl cyanide. The reaction was quenched by adding to 2 liters of water, then extracted three times with ether (1 liter), washed twice with water (1 liter) and brine (1 liter). Drying over MgSO 4  and concentrating gave 171 gms of crude oil (67% product). The product was distilled under vacuum and afforded 104 gms of yellow oil (82.5% yield based on mesylate) having a boiling point of 165°-170° C. at 2 mm Hg. 
     NMR (60 MHz): 1.9-2.4(m, 2H), 2.5-2.7(m, 2H), 3.7(s, 4H), 6.8-7.2(ABq, 4H) and 7.5(s, 5H). 
     Step 2--Preparation of 1-bromo-2-cyano-2-phenyl-4-(4-methoxyphenyl)butane 
     A 4 neck 1 liter round bottom flask was charged with 100 grams (0.40 mole, 1.0 eq.) of alpha-[2-(4-methoxyphenyl)ethyl]phenylacetonitrile and 139.1 gms of dibromomethane in 200 ml of DMSO. To the reaction was added 79.6 gms of 50% NaOH (0.99 mole, 2.5 eq.) dropwise over 15 minutes. The reaction exothermed to 95° C. then was cooled to 50° C. and stirred for 1 hour at 50° C. When gas liquid chromatography indicated the reaction was complete, the reaction product was poured into 2 liters of water, extracted three times with ether (500 ml), washed with water (1 liter), brine and dried over sulfate. 130 gms (94% yield) of product as an amber oil resulted after concentrating. The product was used directly in the triazole coupling. 
     NMR (60 MHz): 2.4-2.8(m, 4H), 3.7(s, 2H), 3.8(s, 3H), 6.8-7.3(ABq, 4H) and 7.5-7.8(br s, 5H). 
     Step 3--Preparation of alpha-[2-(4-methoxyphenyl)ethyl]-alpha-phenyl-1,2,4-triazole-1-propanenitrile 
     A 1 liter 3 neck flask was charged 57 gms of triazole (0.74 mole, 2.0 eq.) in 300 ml of DMSO and 102 gms of K 2  CO 3  (0.74 mole, 4.0 eq.). The reaction was stirred at 135° C. for 1 hour after which 127 gms of 1-bromo-2-cyano-2-phenyl-4-(4-methoxyphenyl)butane (0.37 mole, 1.0 eq.) in 200 ml of DMSO was added. The temperature dropped to 115° C. and was heated at 135° C. for 2 hours then at 80° C. for 18 hours. The reaction was poured into water (3 liter), extracted five times with ethyl acetate (500 ml), washed twice with water (500 ml) and 500 ml of brine. After drying over sulfate, filtering and concentrating gave a yellow oil which was slurried in hexane. A yellow solid formed which was filtered with 10% diethyl ether/90% hexanes. Drying yielded 95 gms of a product having a melting point of 91°-94° C. (77.4% yield). 
     NMR (60 MHz): 2.4-2.9(m, 4H), 3.9(s, 3H), 5.1(s, 2H), 6.8-7.4(ABq, 4H), 7.7-7.9(br s, 5H), 8.2(s, 1H) and 8.4(s, 1H).

     The compounds of the present invention were tested for activity against a number of diseases. The test compounds were dissolved in acetone, methanol and water to form a series of dilutions from 300 ppm to 5 ppm. Depending on when the tests were run, various serial dilutions were used, e.g., 300, 75, 19, 5 or 100, 25, 6. Unless otherwise indicated the plants were sprayed to run-off with a mechanical sprayer the same day or the day before innoculation. The protocol for Wheat Stem Rust (WSR), Wheat Leaf Rust (WLR), Wheat Powdery Mildew (WPM) and Rice Blast (RB) were as follows: 
     WHEAT STEM RUST (WSR)--Puccina graminis 
     Wheat seedlings cultivar TYLER were grown in redi-earth and used for screening about seven days after planting. The seedlings were fertilized with LIQUID-M* fertilizer prior to use to maintain vigorous plants throughout the testing period. 
    
     Depending on when the test was run one of three methods was used to prepare the urediospore suspensions: 
     1. Water/Devilbiss Atomizer: A spore suspension of WSR was prepared by harvesting infected leaves from two to three week old culture plants and shaking the leaves vigorously with water plus TWEEN 80** surfactant. The spore suspension was filtered through cheesecloth to remove debris and adjusted to three to five spores per large square on a hemocytometer. The inoculum was applied to plants by using a Devilbiss atomizer. While the plants were still wet, they were placed in a humidity cabinet. 
    
     2. Oil/Devilbiss Atomizer: A spore suspension of WSR and oil was prepared by harvesting spores fresh from infected plants two to three weeks old with a vacuum pump or rust collector or rehydrating frozen spores (from deep freeze) and adding to SOLTROL*** spray oil at a concentration of five mg spores to one ml oil. The inoculum was applied to the plants with a Devilbiss Atomizer making one pass over the plants from all four sides. The plants were allowed to dry about twenty minutes and then placed in a humidity cabinet. 
    
     3. Oil/Small Special Atomizer: The spore suspension was prepared the same as in method no. 2 except four mg spores per one ml oil was used. The inoculum was then dispensed into gelatin capsules and applied with a vacuum pump. Four passes were made on both sides of the plant for uniformity. The plants were allowed to dry about twenty minutes and then were placed in a humidity cabinet. 
     The humidity cabinet supplied 100% free water and was maintained at a constant temperature of 70° F. The inoculated plants were subjected to twelve hours of darkness followed by three to four hours of fluorescent light. The plants were then transferred into the greenhouse and evaluated thirteen days later. 
     WHEAT LEAF RUST (WLR)--Puccinia recondita 
     The same procedures used for WSR were used for WLR except that for WLR there was no light requirement. 
     WHEAT POWDERY MILDEW (WPM)--Erysiphe graminis 
     Wheat seedlings cultivar VICTORY 283 were grown in redi-earth. The seedlings were six to seven days old and were fertilized with LIQUID-M fertilizer before use to promote vigorous growth throughout the test period. 
     The seedlings were inoculated by shaking sporulating culture plants over them, disseminating mildew spores. The inoculated seedlings were placed in subirrigation trays in a controlled temperature room which provided a 70° F. environment for disease development. 
     Since WPM development is greatly affected by volatile chemicals, the pots were spread out as much as possible and the trays are separated according to dose by plastic sheets. Disease development was rated seven to ten days after inoculation on a percent control basis. 
     RICE BLAST (RB)--Pricularia oryzae 
     Seedlings of the rice cultivar M-201 were grown in a greenhouse at 20°-30° C. in 2-inch pots containing unsterilized soil and Turf-Builder* soil/fertilizer for 14 days. The rice plants were not trimmed before use. 
    
     Inoculum was produced in-vitro on oatmeal agar (50 g Gerber** baby oatmeal, 20 g bacto agar, 10 g bacto dextrose, 100 ml deionized water). The plates were inoculated with a mycelial plug (7-14 days old) of Piricularia oryzae. The outer edge of the dark region was used in the transfer. Inoculated plates were maintained at room temperature under constant fluorescent light. 
    
     P. oryzae plates 10-14 days old were flooded with a solution containing 0.25 g sodium oleate, 2 g gelatin and 100 ml deionized water. The plates were scraped with a rubber policeman to release conidia, filtered through a double layer of cheesecloth and spore suspension adjusted to 25,000-30,000 spores/ml using a hemacytometer. 
     The spore suspension was sprayed on opposite sides of a double row of rice plants using a hand sprayer. Sufficient inoculum was applied to achieve uniform distribution from soil to tip of rice leaves on opposite sides of each pot (approx. 50 ml/50 pots). The hand sprayer was shook after each pass to keep the solution in suspension. 
     The inoculated plants were immediately placed in a humidity cabinet at 25° C. for 66 hours prior to moving them to the greenhouse under a plastic tent. The plants were subirrigated but not allowed to stand in water more than 2 hours. The plastic sides of the tent were lifted during work hours and closed at end of day. 
     After 76 hours under greenhouse conditions the bioassay plants were observed and the percent disease control (as compared to inoculated control) was estimated. 
     The compounds were tested at different dose rates depending on when the tests were run. The results of the tests are set forth in Table 6 for one dose rate for each compound. If the compound was tested more than once at the dose rate, the average is reported.

     The activity of a number of the compounds of the present invention was tested against Peanut Cercospora (PC), Barley Helminthosporium (BH) and Wheat Septoria Nodorum (SNW). The protocol for these tests was as follows: 
     PEANUT CERCOSPORA OR PEANUT EARLY LEAFSPOT (PC)--Cercospora arachidicola 
     Cercospora arachidicola was cultured on peanut-oatmeal agar (POA) in petri plates for 14 days under fluorescent lights that were 20 cm above the cultures. The petri plates were inoculated with 0.5 ml of a spore suspension made in sterile water containing a few drops of Tween 80. The spore suspension was subsequently spread over the surface of the POA plate by means of a sterile glass rod bent in the form of a hockey stick. Spores were harvested from the plates by adding deionized water containing a small amount of Tween 80 to the POA plates. The agar surface was scraped with a rubber policeman or similar blunt object. The spore suspension was filtered through cheesecloth to remove mycelial and agar fragments and then adjusted to a concentration of 2-4×10 5  spores per ml. 
     Fourteen day old TAMNUT 74 peanut plants were inoculated by spraying the leaves with inoculum until a uniform film of inoculum was observed on the plant. The inoculated plants were incubated in a humid environment at 85°-90° F. for 72 hours. The plants were removed from the humid environment, allowed to dry, and placed in a greenhouse. Treatment comparisons were made 10-14 days after inoculation. 
     BARLEY HELMINTHOSPORIUM or BARLEY SPOT BLOTCH TEST (BH)--Helminthosporium sativum 
     Seven day old HENREY barley seedlings in 2&#34; pots were trimmed 24 hours prior to chemical application to provide a uniform plant height and to facilitate uniform inoculation. The plants were sprayed with the test compound via a settling tower (1.1 ml of the desired concentration for each spray). The spray was allowed to settle in the tower for one minute before removing the plants from the tower. After spraying, the plants were allowed to dry for at least 2 hours in a drying hood before inoculation. 
     The Helminthosporium sativum culture used for inoculum was about 3 weeks old, deep black and sporulating. Five ml of deionized water was added to each Petri dish of culture and the spores were scraped off into the water with a rubber policeman. After scraping, the water was filtered through cheesecloth to remove mycelia and agar pieces. One drop of TWEEN 80 surfactant was added to each 100 ml of spore suspension. The spore concentration was adjusted to 25 spores/ml. Inoculum was applied using a hand sprayer. The inoculated plants were put into a greenhouse after sitting in a humidity cabinet at about 70° F. for 24 hours. The plants were allowed to sit in the greenhouse for 6 days prior to scoring the test. The disease was assessed according to &#34;A MANUAL OF ASSESSMENT KEYS FOR PLANT DISEASES&#34; by Clive James (Key No 1.6.1) 
     WHEAT GLUME BLOTCH (SNW)--Septoria nodorum 
     The inoculum was produced by placing pieces of sporulating mycelium from 3 week old plates on Czapek-Dox V-8 plates or placing a piece of sporulating mycelium in a test tube containing 20 ml of sterile deionized water, shaking well and after 5 minutes placing enough liquid spore mixture in a fresh plate to make a fine film over the plate. The plates were incubated for 48 hours at 20° C. in darkness until a white mycelium was observed. Then plates were incubated at 21° C. under continuous fluorescent light for 15-20 days. The mycelium had a pink color at the end of the incubation period. 
     The sporulating plates were flooded with deionized water. The spores were scraped into the water with a rubber policeman. The flooding and scraping was repeated 2-3 times with each plate. The spore suspension was then filtered with cheesecloth. The final spore concentration was adjusted 150-300 spores/ml. Two drops of TWEEN 80 per 500 ml of spore suspension were added. 
     LEN wheat plants were inoculated by spraying the leaves with the spore suspension and TWEEN 80 using a hand sprayer after optionally spraying the plants with a light mineral oil lightly and waiting 5 minutes. The inoculated plants were incubated for 72 hours in a humidity cabinet at 20° C. with a photoperiod of 16 hours light/8 hours dark. The plants were then placed in a growth chamber for 7-9 days at 20° C. with a photoperiod of 16 hours light/8 hours dark and then evaluated for percent control. 
     The compounds were tested at different dose rates depending on when the tests were run. The results of the tests for the better compounds which were tested are set forth in Table 8 for three rates. If the compound was tested at the same dose rate more than once, the average is reported.

     COMPARATIVE TESTING 
     Compounds 2 and 10 versus comparative Compounds C2a, C2b and C10 
     Side by side in vitro comparative testing of Compounds 2, 10, C2a, C2b and C10 were done against P. herpotrichoides and Septoria tritici. The tests were performed by routine PDA poison agar as follows: 
     POISON AGAR TEST 
     Thirty-nine grams of potato dextrose agar (PDA) purchased from Difco was suspended in 1 liter of water. The media was autoclaved at 15 psi for 15 minutes. After autoclaving, the media was allowed to cool for 15 minutes. Then a dilution series was prepared by adding a known amount of fungicide to the molten agar. The fungicide was dissolved in methanol, acetone or DMSO previous to mixing with the agar. The fungi were rated for growth after the following incubation periods: 
     Pseudocercosporella herpotrichoides--12 days at room temp. 
     Septoria tritici--14 days at room temp. 
     The results were reported in millimeters of radius and the EC 75  was calculated. The EC 75  values in ppm were as follows: 
     
         ______________________________________PseudocercosporellaC2a            C2b      2(phenyl)       (benzyl) (phenethyl)______________________________________20             12       0.6______________________________________          C10      10          (benzyl) (phenethyl)______________________________________          20       0.2______________________________________Septoria triticiC2a            C2b      2______________________________________ 8             10       0.2______________________________________          C10      10______________________________________           4        0.02______________________________________ 
    
     Therefore, the compound of the present invention has an EC 75  at least 20 times less than the corresponding phenyl or benzyl compounds. 
     Compound 6 versus comparative Compound C6 
     In vivo side by side comparative testing of Compound 6 and comparative Compound C6 was also performed. 
     Control of Barley Spot Blotch 
     High volume sprays in acetone:methanol:water were applied on an overhead mechanical sprayer to Pennrad barley seedlings in 3 inch pots. The EC 75  values were calculated and are set forth in Table 9 below. As shown, the compound of the present invention has an EC 75  more than 20 times less than the corresponding benzyl compound when treated the day of inoculation. 
     Control of Wheat Leaf Rust with Foliar Sprays 
     The compounds were suspended in acetone:methanol:water and were sprayed to run-off on an overhead mechanical sprayer onto Pennol wheat seedlings in 3 inch pots. The plants were inoculated with aqueous suspensions of urediospores (20,000/ml) of Puccinia recondita and were incubated for 24 hours at 70° F. in mist and for a further 7 days in a greenhouse. The EC 75  values were calculated and are set forth in Table 9 below. 
     Control of Wheat Powdery Mildew with Foliar Sprays 
     Routine foliar spray using Pennol wheat seedlings in 3 inch pots were performed. The EC 75  values in ppm were calculated and are set forth in Table 9 below.

     As can be seen from the above data, the compound of the present invention clearly controls barley spot blotch better than the comparative compound. Although Compound 6 of the present invention is not one of the better compounds against wheat leaf rust or wheat powdery mildew and the strength of the benzyl series is against the wheat fungi, compound 6 is only somewhat poorer in controlling wheat leaf rust than the comparative benzyl compound and Compound 6 is better against wheat powdery mildew when inoculated on the day of treatment. 
     Compound 10 versus comparative Compound C10 
     Control of Wheat Powdery Mildew and Wheat Leaf Rust 
     On two occasions in vivo side by side comparative testing of Compound 10 and comparative Compound C10 was performed using the protocol set forth before Table 6. The results of the two tests are set forth below: 
     
         ______________________________________WPM                WLRCompound/Dose rate in ppm ai100        25       6      100    25   6______________________________________Test 110      99     95       95   100    100  99C10     95     95       85   95     85   85Test 210      100    95       95   100    100  99C10     100    95       95   95     85    0______________________________________ 
    
     Compound 10 is superior to the comparative compound against wheat leaf rust and as good or better than the comparative compound against wheat powdery mildew. 
     Based on the foregoing comparative tests the phenethyl compounds are overall superior to corresponding benzyl and phenyl compounds. The compounds of the present invention are more than one magnitude better against Wheat Foot Rot (Pseudocercosporella), Wheat Leaf Blotch (Septoria tritici) and Barley Spot Blotch (Helminthosporium sativum), and generally superior against Wheat Leaf Rust (Puccinia recondita) and Wheat Powdery Mildew (Erysiphe graminis). 
     The clear advantage of the phenethyl triazoles of the present invention is their overall superior efficiency against a number of fungi. The preferred compounds of the present invention have good fungicidal activity against Barley Spot Blight, Peanut Early Leafspot and Rice Blast as well as Wheat Leaf Rust and Wheat Stem Rust.
