     DETAILED DESCRIPTION OF THE INVENTION 
     Synthesis 
     I. Synthesis of 1,5-Disubstituted-1,2,4-Triazoles 
     The compounds of Formula Ia, in which Y is H, can be prepared from compounds of Formula II by the methods described below. ##STR21## Compounds of Formula II can be prepared by various methods, as disclosed in U.S. Pat. Nos. 4,510,136 and 4,530,922. 
     A. Metalation and Subsequent Functionalization 
     The metalation of II with strong bases (Equation 1) provides the 5-metalated triazoles III (R. G. Micetich et al., Heterocycles 1985, 23, 1645-49). 
     Equation 1 ##STR22## 
     Suitable bases include organoalkali metal compounds, such as n-butyllithium, and alkali metal amides, such as lithium diisopropylamide. Appropriate solvents for the metalation include hydrocarbons such as toluene, and ethereal solvents such as tetrahydrofuran (THF), dimethoxyethane (DME) and diethyl ether. The metalations can be carried out from -80° C. to 60° C. for periods of 1 to 120 minutes, depending on the choice of base, solvent and substrate. Typical conditions involve treatment of a solution of II in THF at -70° C. with n-butyllithium for 15 minutes, which gives III where the metal is lithium. When R 2  or R 3  is OH, two equivalents of base are required. 
     Other methods for the preparation of organo-metallic compounds which are known to one skilled in the art are applicable to the preparation of III, and include halogen-metal exchange between halotriazoles and organometallic compounds, reductive metalation of halotriazoles and the reaction of III with anhydrous metal salts. For a review, see J. March. Advanced Organic Chemistry, 3rd Edition, J. Wiley and Sons, New York, N.Y., 1985, p. 1169-1170. 
     The use of organometallic compounds of Formula III in appending a wide variety of functional groups to metalated carbon centers has been reviewed (H. G. Gschwend and H. R. Rodriguez, Organic Reactions, Volume 26, W. G. Dauben, Ed., J. Wiley and Sons, New York, N.Y., 1979, p. 1; J. March, op. cit., see Index under Grignard reagents, p. 1314). More specifically, transformations of III to compounds of this invention are discussed below according to the type of bond formed to C-5 of the triazole ring. 
     Metalation of a 1-substituted imidazole, by analogy to Equation 1 above, yields a 2-metalated imidazole analogous to the compound of Formula III. Subsequent treatment according to the methods described for triazoles provides 1,2-disubstituted imidazoles analogous to the compounds of Formula Ia. 
     1. Bonds to Carbon 
     The conversion of compounds of Formula III to compounds of this invention having C-5 carbon bonds is outlined in Scheme I and involves standard transformations known to one skilled in the art. Some examples are given below. 
     Scheme I ##STR23## 
     The reaction of compounds of Formula III with acid derivatives such as dialkylamides provides acyltriazoles V (S. Ohta et. al., Heterocycles 1985, 23, 1759-64). 
     Treatment of III with CO 2 , COS or CS 2  provides the metal salts of the 5-triazole carboxylic acids, thioacids and dithioacids. In some cases, the parent carboxylic acids readily decarboxylate. (Micetich, op.cit.). Alkylation of these metal salts with, for example, non-aryl R 14  iodides in methyl ethyl ketone or THF provides esters, thioesters or dithioesters of Formula VI. These esters are precursors of VI where R 14  constitutes an aryl group, via exchange reactions of R 14  OH or R 14  SH under the influence of basic or acidic catalysis. 
     The 5-formyltriazoles of Formula V are intermediates for the preparation of other C-5 carbon bond compounds of this invention using methods known to one skilled in the art, as shown in Scheme II. For example, the reaction of 5-formyltriazoles with dibromomethylenetriphenylphosphorane provides dibromoolefins VIII (W=Br) which may be converted to alkynes of Formula IX using n-butyllithium (E. J. Corey et al., Tetrahedron Lett. 1972, 3769). 
     Scheme II ##STR24## 
     2. Bonds to Sulfur or Selenium 
     The conversion of compounds of Formula III to mercaptan metal salts or mercaptans X (X=SH) can be carried out using standard procedures (see March, op. cit., p. 550). These can be converted to other compounds of this invention having C-5 sulfur bonds following procedures known to one skilled in the art, as shown in Scheme III. For example, disulfides of Formula XIV can be prepared by treatment of thiols X with sulfenyl chlorides or phthalimidosulfides in inert solvents (D. N. Harpp et al., Tetrahedron Lett. 1970, 3551). Sulfenamides of Formula XIII are available by the reaction of disulfides XII with lithium dialkylamides (H. Ikehira et al., Synthesis 1983, 716) and by treatment of sulfenyl halides with amines (R. Lejeune et al., J. Pharm. Belg. 1984, 39, 217). ##STR25## 
     Sulfides of Formula XI can be converted to sulfoxides and sulfones using standard procedures. 
     The selenides and selenoxides of the present invention can be prepared using methods similar to those employed for the preparation of sulfides of Formula XI and corresponding sulfoxides. 
     The thiols of Formula X are precursors to other C-5 sulfur substituted compounds of this invention as shown in Scheme IV. For example, treatment of thiols X with cyanogen halides provides thiocyanates of Formula XV (C. Temple and J. A. Montgomery, Triazoles, Vol. 37 of Heterocyclic Compounds, A. Weissberger and E. C. Taylor, Eds., J. Wiley and Sons, New York, N.Y., 1981, p. 257). Treatment of X with R 14  NCY (Y=O or S) provides thiocarbamates XVI (ibid.). ##STR26## 
     3. Bonds to Other Elements 
     The preparation of 5-halotriazoles of Formula Ia can be carried out using methods known to one skilled in the art (see Gschwend, op. cit., p. 83 and March, op. cit., p. 551). For example, treatment of III, where the metal is lithium, with iodine provides Ia where X is iodine (Equation 2). 
     Equation 2 ##STR27## 
     Treatment of III in ethereal solvents such as THF with R 15  O(R 14  O)P(Cl)O where R 15 , R 14  ≠H gives C-5 phosphates. Treatment with iodotrimethylsilane, then water, where R 15 , R 14  are n-alkyl or benzyl, gives the C-5 phosphonic acids. 
     Amination of III can be carried out using CH 3  ONHR 12  (March, op. cit., p. 553). Alternatively, III can be reacted with an arenesulfonyl azide, followed by reduction with, e.g., NaBH 4  (J. N. Reed and V. Snieckus, Tetrahedron Lett. 1983, 24, 3795). The resulting amines can be alkylated or oxidized to compounds where X=NO 2  using methods known to one skilled in the art. 
     B. Other Methods 
     Compounds of the present invention where X=NR 9  NR 12  R 14  are available by the reaction of, for example, the 5-bromotriazoles with hydrazines (Temple and Montgomery, Triazoles, op. cit., p. 291). 
     Compounds of Formula II react with sulfenyl halides, such as perchloromethylmercaptan in inert solvents such as methylene chloride, in the presence of triethylamine to give sulfides of Formula XI. 
     II. Synthesis of 1,3-Disubstituted-1,2,4-Triazoles 
     The compounds of Formula Ib in which X is H, can be prepared by alkylation of silylmethyl halides XXII or sulfonate esters with metal salts of Z 1  -substituted triazoles, where Z 1  is Y or can be converted to Y using known procedures. Examples of ##STR28## Z 1  to Y conversions are given in Section I: Synthesis of 1,5-Disubstituted-1,2,4-Triazoles. It is understood that with this procedure, mixtures of 1,3- and 1,5-disubstituted-1,2,4-triazoles may be produced, from which the desired isomers can be isolated using standard techniques. 
     A variety of substituted triazoles are available using literature procedures (Temple and Montgomery, Triazoles, op. cit., see Index). Alkylation of halomethylsilanes as described in U.S. Pat. Nos. 4,510,136 and 4,530,922 with Z 1  -substituted triazoles, where Z 1  is Y or can be converted to Y using standard procedures, provides silylmethyl-(Z 1  -substituted) triazoles. For example, 1,2,4-triazole-3-thiol can be alkylated with trityl chloride (T. W. Greene, Protective Groups in Organic Synthesis, J. Wiley and Sons, New York, N.Y., 1981, p. 201). The potassium salt of the resulting tritylthiotriazole can be allowed to react with halomethylsilanes and the product deprotected (Greene, loc. cit.) (Equation 3). The 3-mercaptotriazole XX can be converted to other compounds of Formula Ib having C-3 sulfur bonds. 
     Equation 3 ##STR29## 
     Similarly, alkylation of halomethylsilanes with a metal (e.g., potassium) salt of 3-nitro-1,2,4-triazole provides the analogous 3-nitro-1-silylmethyltriazole, which can be reduced to give the 3-amino compound. 
     Similar reactions are possible for other values of Z 1  (X, Y), and in many cases no protection-deprotection is required. Depending on Z 1  (X, Y) and the reaction conditions used, varying amounts of 5-substituted 1-silylmethyltriazoles may also be prepared. The 3- and 5-substituted triazoles may be separated by standard methods, such as chromotography. 
     In the following examples, temperatures are reported in degrees Celsius. Abbreviations for nuclear magnetic resonance (nmr) spectra are s=singlet, d=doublet, t=triplet, q=quartet, m=multiplet, br=broad; peak positions are reported as parts per million downfield from tetramethylsilane. Hexanes refers to a mixture of isomers boiling from 68°-69° and ether refers to diethyl ether. All reactions involving organo-metallic reagents or metal hydrides were run under an atmosphere of dry nitrogen. &#34;Flash&#34; chromatography refers to the method described by Still et al. (J. Org. Chem. (1978) 43, 2923).

     Utility 
     The compounds of this invention are useful as plant disease control agents. They are effective in controlling a broad spectrum of plant diseases, particularly foliar pathogens of ornamental, vegetable, field, cereal and fruit crops, such as, Puccinia recondita, Sphaerotheca fuliginea, Erysiphe graminis, Podosphaera leucotricha, Venturia inaequalis, Pyricularia oryzae, Bipolaris oryzae, Cercospora arachidicola, Cercospora beticola and Monilinia fructicola. They also control soil borne pathogens such as Rhizoctonia solani. 
     Formulation 
     The compounds of this invention will generally be used in formulations with a liquid or solid diluent or with an organic solvent. Useful formulations of the compounds of Formula I can be prepared in conventional ways. They include dusts, granules, pellets, solutions, emulsions, wettable powders, emulsifiable concentrates and the like. Many of these may be applied directly. Sprayable formulations may be extended in suitable media and used at spray volumes of from about one to several hundred liters per hectare. High strength compositions are primarily used as intermediates for further formulation. The formulations, broadly, contain about 1% to 99% by weight of active ingredient(s) and at least one of (a) about 0.1% to 35% surfactant(s) and (b) about 5% to 99% solid or liquid inert diluent(s). More specifically, they will contain these ingredients in the following approximate proportions:

     Lower or higher levels of active ingredient can, of course, be present depending on the intended use and the physical properties of the compound. Higher ratios of surfactant to active ingredient are sometimes desirable, and are achieved by incorporation into the formulation or by tank mixing. 
     Typical solid diluents are described in Watkins, et al., &#34;Handbook of Insecticide Dust Diluents and Carriers&#34;, 2nd Ed., Dorland Books, Caldwell, N.J. The more absorptive diluents are preferred for the wettable powders and the denser ones for dusts. Typical liquid diluents and solvents are described in Marsden, &#34;Solvents Guide,&#34; 2nd Ed., Interscience, N.Y., 1950. Solubility under 0.1% is preferred for suspension concentrates; solution concentrates are preferably stable against phase separation at 0° C. &#34;McCutcheon&#39;s Detergents and Emulsifiers Annual&#34;, MC Publishing Corp., Ridgewood, N.J., as well as Sisely and Wood, &#34;Encyclopedia of Surface Active Agents&#34;, Chemical Publ. Co., Inc., New York, 1964, list surfactants and recommended uses. All formulations can contain minor amounts of additives to reduce foam, caking, corrosion, microbiological growth, etc. Preferably, ingredients should be approved by the U.S. Environmental Protection Agency for the use intended. 
     The methods of making such compositions are well known. Solutions are prepared by simply mixing the ingredients. Fine solid compositions are made by blending and, usually, grinding as in a hammer or fluid energy mill. Suspensions are prepared by wet milling (see, for example, Littler, U.S. Pat. No. 3,060,084). Granules and pellets may be made by spraying the active material upon preformed granular carriers or by agglomeration techniques. See J. E. Browning, &#34;Agglomeration&#34;, Chemical Engineering, Dec. 4, 1967, pp. 147ff. and &#34;Perry&#39;s Chemical Engineer&#39;s Handbook&#34;, 4th Edn., McGraw-Hill, N.Y., 1963, pp. 8-59ff.

     Application 
     Disease control is ordinarily accomplished by applying an effective amount of the compound, normally as part of a formulation containing it, either pre- or post-infection to the portion of the plant to be protected, such as the roots, stems, foliage, fruit, seeds, tubers or bulbs, or to the medium (soil or sand) in which the plants to be protected are growing. The compound may also be applied to the seed from which the plants to be protected are to be grown. 
     Rates of application for these compounds can be influenced by many factors of the environment and should be determined under actual use conditions. Nevertheless, foliage can normally be protected when treated at a rate of from 1 gram or less up to 5000 grams of active ingredient per hectare. Plants growing in soil that is treated at a concentration from about 0.1 to about 20 kg of active ingredient per hectare can be protected from disease. Seed and seedlings can normally be protected when seed is treated at a rate of from about 0.06 to about 3 grams of active ingredient per kilogram of seed. 
     In the following Examples 22-34, the percent disease control is determined as the percent growth inhibition of colonies on treated plants as compared to untreated plants. Results for Examples 22-34 are given in Table VI. In the table, a rating of 100 indicates 100% disease control and a rating of 0 indicates no disease control relative to the controls. A &#34;-&#34; entry indicates that no test was performed with the specified compound. The number of the test compound corresponds to the similarly numbered compound in Tables I-V.
