In the above recitations, when a compound of Formula I is comprised of one or more heterocyclic rings, all substituents are attached to these rings through any available carbon or nitrogen by replacement of a hydrogen on said carbon or nitrogen. When a compound is substituted with a substituent bearing a subscript that indicates the number of said substituents can exceed 1, said substituents (when they exceed 1) are independently selected from the group of defined substituents. Further, when the subscript indicates a range, e.g., (R)i_j, then the number of substituents may be selected from the integers between ii and j inclusive. When a group contains a substituent which can be hydrogen, for example R4, then, when this substituent is taken as hydrogen, it is recognized that this is equivalent to said group being unsubstituted. When a group is optionally substituted with a substituent, for example with R7, then, when the group is not substituted with that substituent, it is recognized that this is equivalent to said group having a hydrogen substituent. Compounds used in this invention often can exist as one or more stereoisomers. The various stereoisomers include enantiomers, diastereomers, atropisomers and geometric isomers. One skilled in the art will appreciate that one stereoisomer may be more active and/or may exhibit beneficial effects when enriched relative to the other stereoisomer(s) or when separated from the other stereoisomer(s). (See, e.g., U.S. Provisional Patent Application Serial No. 60/057917 filed September 4,1997, which is hereby incorporated by reference in its entirety.) Additionally, the skilled artisan knows how to separate, enrich, and/or to selectively prepare said stereoisomers.

It is uniquely identified by the Enzyme Commission number ECl. 10.2.2. The bc\ complex is described in, for example, J. Biol Chem. 1989, 264,14543-38; Methods Enzymol 1986,126, 253-71; and references cited therein. The Sterol Biosynthesis Inhibitor Fungicides The class of sterol biosynthesis inhibitors includes DMI and non-DMI compounds, that control fungi by inhibiting enzymes in the sterol biosynthesis pathway. DMI fungicides have a common site: of action within the fungal sterol biosynthesis pathway; that is, an inhibition of demethylation at position 14 of lanosterol or 24-methylene dihydrolanosterol, which are precursors to sterols in fungi. Compounds acting at this site are often referred to as demethylase inhibitors, DMI fungicides, or DMIs. The demethylase enzyme is sometimes referred to by other names in the biochemical literature, including cytochrome P-450 (14DM). The demethylase enzyme is described in, for example, J. Biol. Chem. 1992, 267,13175-79 and references cited therein. DMI fungicides fall into several classes: triazoles, imidazoles, pyrimidines, piperazines and pyridines. The triazoles includes bromuconazole, cyproconazole, difenoconazole, diniconazole, epoxiconazole, fenbuconazole, fluquinconazole, flusilazole, flutriafol, hexaconazole, ipconazole, metconazole, penconazole, propiconazole, tebuconazole, tetraconazole, triadimefon, triadimenol, triticonazole and uniconazole. The imidazoles include clotrimazole, econazole, imazalil, isoconazole, miconazole and prochloraz. The pyrimidines include fenarimol, nuarimol and triarimol. . The piperazines include triforine. The pyridines include buthiobate and pyrifenox. Biochemical investigations have shown that all of the above mentioned fungicides are DMI fungicides as described by K. H. Kuck, et al. in Modern Selective Fungicides -Properties, Applications and Mechanisms of Action, Lyr, H., Ed.; Gustav Fischer Verlag: New York, 1995, 205-258. The DMI fungicides have been grouped together to distinguish them from other sterol biosynthesis inhibitors, such as, the morpholine and piperidine fungicides. The morpholines and piperidines are also sterol biosynthesis inhibitors but have been shown to inhibit later steps in the sterol biosynthesis pathway. The morpholines include aldimorph, dodemorph, fenpropimorph, tridemorph and trimorphamide. The piperidines include fenpropidin. Biochemical investigations have shown that all of the above mentioned morpholine and piperidine fungicides are sterol biosynthesis inhibitor fungicides as described by K. H. Kuck, et al. in Modern Selective Fungicides -Properties, Applications and Mechanisms of Action, Lyr, H., Ed.; Gustav Fischer Verlag: New York, 1995, 185-204. Synergistic Effects Fungicides that effectively control plant fungi, particularly wheat powdery mildew {Erysiphe graminis) and wheat foot rot {Pseudocercosporella herpotrichoides), are in constant demand by growers. Combinations of fungicides are often used to facilitate disease control and to retard resistance development. Mixtures of fungicides may provide significantly better disease control than could be predicted based on the activity of the individual components. This synergism has been described as "the cooperative action of two components of a mixture, such that the total effect is greater or more prolonged than the sum of the effects of the two (or more) taken independently" (see Tames, P. M. L., Neth. J. Plant Pathology, (1964), 70, 73-80). It has been demonstrated that compositions containing compounds of Formula la and Formula Ha; Formula la and flusilazole; Formula la and tebuconazole; and Formula la, Formula Ila and flusilazole exhibit synergistic effects. The presence of a synergistic effect between two active ingredients is established with the aid of the Colby equation (see Colby, S. R. In Calculating Synergistic and Antagonistic Responses of Herbicide Combinations, Weeds, (1967), 15, 20-22): 21 Ax B p=A+B- 100 Using the methods of the Colby, the presence of a synergistic interaction between two active ingredients is established.by first calculating the predicted activity, p, of the mixture based on activities of the two components applied alone. If p is lower than the experimentally established effect, synergism has occurred. In the equation above, A is the fungicidal activity in percentage control of one component applied alone at rate x. The B term is the fungicidal activity in percentage control of the second component applied at rate y. The equation estimates p, the fungicidal activity of the mixture of A at rate x with B at rate y if their effects are strictly additive and no interaction has occurred. The Colby equation for a three way mixture is p = A + B + C+ AxBxC . 10000 (A x B) + (A x O + (B x C) 100 In this application, fungicidal activities provided by compositions of Formula la, Formula Ha, flusilazole and tebuconazole alone are compared with that of compositions of the compounds of Formula la and Formula Ha together, compositions of the compounds of Formula la and flusilazole together, compositions of the compounds of Formula la and tebuconazole together, and compositions of the compounds of Formula la, Formula Ha and flusilazole together. Based on the description of synergism developed by Colby, compositions of the present invention are considered to be synergistically useful. Accordingly, this invention provides an improved method of combating fungi, such as wheat powdery mildew {Erysiphe graminis), wheat leaf rust {Puccinia recondita), wheat foot rot {Pseudocercosporella herpotrichoides) and/or wheat glume blotch {Septoria nodorum) in crops, especially cereals. Compositions are provided in accordance with this invention which comprise proportions of component (1) and component (2) which are especially useful for controlling particular fungal diseases. For example, the compositions of this invention include those wherein the mole ratio of component (1) to component (2) is from about 30:1 to 1:30. These compositions are considered especially useful for controlling wheat powdery mildew {Erysiphe graminis), wheat leaf rust {Puccinia recondita), wheat foot rot {Pseudocercosporella herpotrichoides) and/or wheat glume blotch {Septoria nodorum).

Synthesis of Compounds of Formula I The compounds of Formula I where D is O can be prepared as described in International Patent Application WO 94/26722 and as shown in Scheme 1. An anthranilic acid (2-aminobenzoic acid) of Formula 1 is condensed with an isothiocyanate of Formula R!-NCS to form the 2-thioquinazolinedione of Formula 2. This condensation is preferably performed in the presence of a base such as triethylamine. S-Methylation of this compound affords the 2-methylthio-4(3H)-quinazolinone of Formula 3. For the introduction of the R2O group, the 2-methylthio-4(3//)-quinazolinone of Formula 3 is treated with a mixture of a base, for example sodium hydride, in R2OH solvent. The reaction mixture is stirred at a temperature from about 0 °C to 120 °C for 1-120 hours. The desired 2-R2O-4(3H)-quinazoIinone can be isolated from the reaction mixture by extraction into a water-immiscible solvent, and purified by chromatography or recrystallization. Similar synthetic procedures are described in U.S. 3,755,582, incorporated herein by reference. 27 Scheme 1 Anthranilic acids of Formula 1 are known or can be prepared by known methods. For example see, March, J. Advanced Organic Chemistry; 3rd ed., John Wiley: New York, (1985), p 983. The isothiocyanates of Formula Rl-NCS can be prepared from the corresponding amine by treatment with thiophosgene as known in the art. For example, see/. Heterocycl Chem.t (1990), 27,407. 6-Iodo-3-propyl-2-propyloxy-4(3/0-qumazolinone, Formula la, is a compound of Formula I where D is O, R1 is propyl, R2 is propyl, R3 is iodine fixed in the 6 position and R4 is hydrogen. 28 Synthesis of Compounds of Formula II Compounds of Formula II where Q is Q-l and X is OR11 can be prepared as described in International Patent Application WO 95/14009 by treating a compound of Formula 4 with an appropriate alkyl transfer reagent in an inert solvent with or without additional acidic or basic reagents or other reagents (Scheme 2). Suitable solvents are selected from the group consisting of polar aprotic solvents such as acetonitrile, dimethylformamide or dimethylsulfoxide; ethers such as tetrahydrofuran, dimethoxyethane, or diethyl ether; ketones such as acetone or 2-butanone; hydrocarbons such as toluene or benzene; and halocarbons such as dichloromethane or chloroform. Scheme 2 For example, compounds of Formula II where Q is Q-l and X is OR1* can be prepared by the action of diazoalkane reagents of Formula 5 such as diazomethane (V = H) or trimethylsilyldiazomethane (V = (CH3)3Si) on of Formula 4 (Method 1). Use of trimethylsilyldiazomethane requires a protic cosolvent such as methanol. For examples of these procedures, see Chem. Pharm. Bull., (1984), 32, 3759. As indicated in Method 2, compounds of Formula II where Q is Q-l and X is OR1 ] can also be prepared by contacting compounds of Formula 4 with alkyl 29 trichloroacetimidates of Formula 6 and a Lewis acid catalyst. Suitable Lewis acids include trimethylsilyl triflate and tetrafluoroboric acid. The alkyl trichloroacetimidates can be prepared from the appropriate alcohol and trichloroacetonitrile as described in the literature (J. Danklmaier and H. Honig, Synth. Commun., (1990), 20, 203). Compounds of Formula II where Q is Q-l and X is OR1} can also be prepared from compounds of Formula 4 by treatment with a trialkyloxonium tetrafluoroborate (i.e., Meerwein's salt) of Formula 7 (Method 3). The use of trialkyloxonium salts as powerful alkylating agents is well known in the art (see U. SchoTlkopf, U. Groth, C. Deng, Angew. Chem., Int. Ed EngL, (1981), 20, 798). Other alkylating agents which can convert compounds of Formula 4 to compounds of Formula II where Q is Q-1 and X is OR1 * are dialkyl sulfates such as dimethyl sulfate, haloalkyl sulfonates such as methyl trifluoromethanesulfonate, and alkyl halides such as iodomethane and propargyl bromide (Method 4). These alkylations can be conducted with or without additional base. Appropriate bases include alkali metal alkoxides such as potassium terf-butoxide, inorganic bases such as sodium hydride and potassium carbonate, or tertiary amines such as triethylamine, pyridine, l,8-diazabicyclo[5.4.0]undec-7-ene (DBU), and triethylenediamine. See R. E. Benson, T. L. Caims, J. Am. Chem. Soc, (1948), 70,2115 for alkylation examples using agents of this type. Compounds of Formula II where Q is Q-1 and X is OR11 can also be prepared by reaction of Formula 8 compounds with alkali metal alkoxides (R1 ^"M"1") (Scheme 3). The leaving group Lg1 in the amides of Formula 8 are any group known in the art to undergo a displacement reaction of this type. Examples of suitable leaving groups include chlorine, bromine, and sulfonyl and sulfonate groups. Examples of suitable inert solvents are dimethylformamide or dimethylsulfoxide.

In certain instances, combinations with other fungicides having a similar spectrum of control but a different mode of action will be particularly advantageous for resistance management. Plant disease control is ordinarily accomplished by applying an effective amount of the composition of this invention 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 media (soil or sand) in which the plants to be protected are growing. The composition can also be applied to the seed to protect the seed and seedling. Rates of application for this composition can be influenced by many factors of the environment and should be determined under actual use conditions. Foliage can normally be protected when treated at a rate of from less than 1 g/ha to 5,000 g/ha of aggregate active ingredient. Aggregate active ingredient is defined as the total combined weight of active ingredients. Seed and seedlings can normally be protected when seed is treated at a rate of from 0.1 to 10 g of aggregate active ingredient per kilogram of seed. The following Examples demonstrate the composition and method of the present invention and provide experimental evidence for synergy between the compound of Formula la and flusilazole in preventative control of wheat leaf rust caused by Puccinia recondita, wheat foot rot caused by Pseudocercosporella herpotrichoides, and wheat glume blotch caused by Septoria nodorum. The experimental also provides evidence for synergy between the compound of Formula la and tebuconazole in preventative control of wheat leaf rust and wheat glume blotch. The experimental also provides evidence for synergy between the compound of Formula la and flusilazole in curative control of wheat powdery mildew caused by Erysiphe graminisf. sp. tritici and wheat leaf rust. The experimental also pro /ides evidence for synergy between the compounds of Formula la, Formula Ha and flusilazole in preventative control of wheat foot rot. The experimental also provides evidence for synergy between the compounds of Formula la, Ha and flusilazole in curative control of wheat powdery mildew. The pathogen control protection afforded by these compositions is not limited, however, to these species.

The following day the seedlings were inoculated with a spore suspension of Pseudocercosporella herpotrichoides (the causal agent of wheat eye spot or wheat foot rot) and incubated in a saturated atmosphere at 20 °C for 72 h, and then moved to a growth chamber at 20 °C for 6 days, after which disease ratings were made. Protocol # 6 - WGB Preventive The test compounds were sprayed to the point of run-off on wheat seedlings. The following day the seedlings were inoculated with a spore suspension of Septoria nodorum (the causal agent of wheat glume blotch) and incubated in a saturated atmosphere at 20 °C for 48 h, and then moved to a growth chamber at 20 °C for 6 days, after which disease ratings were made. Protocol # 7 - WGB Curative Wheat seedlings were inoculated with a spore suspension Septoria nodorum (the causal agent of wheat glume blotch). Two days later test compounds were sprayed to the point of run-off on and seedlings incubated in a saturated atmosphere at 20 °C for 48 h, then moved to a growth chamber at 20 °C for 6 days, after which disease ratings were made. Protocol # 8 - WPM Preventative The test suspension was sprayed to the point of run-off on wheat seedlings. The following day the seedlings were inoculated with a spore dust of Erysiphe graminis f. sp. tritici, (the causal agent of wheat powdery mildew) and incubated in a growth chamber at 20 °C for 7 days, after which disease ratings were made. Results for protocols 1 - 8 are given in Tables A-G. In the tables, a rating of 100 indicates 100% disease control and a rating of 0 indicates no disease control (relative to the controls). An (nt) indicates no test results and (-) indicates no estimate of activity. In Tables A-G rates are given in parts per million (ppm) and/or grams active ingredient per hectare (g a.i./ha). The term "Actual" stands for the experimental value. The abbreviation "Exp." stands for "Expected" (i.e., the predicted activity, p, from the Colby equation).

BACKGROUND OF THE INVENTION
Fungicides that effectively control plant diseases are in constant demand by growers. Plant diseases are highly destructive, difficult to control and quickly develop resistance to commercial fungicides. Combinations of pesticides are often used to facilitate disease control, to broaden spectrum of control and to retard resistance development. It is recognized in the art that the advantages of particular pesticide combinations can often vary, depending on such factors as the particular plant and plant disease to be treated, and the treatment conditions. Accordingly, there is an ongoing search for advantageous combinations of pesticides.

The term "nonaromatic carbocyclic ring system" denotes fully saturated carbocycles as well as partially or fully unsaturated carbocycles where the Huckel rule is not satisfied by any of the rings in the ring system. The term "aromatic

16
heterocyclic ring system" includes fully aromatic heterocycles and heterocycles in which at least one ring of a polycyciic ring system is aromatic (where aromatic indicates that the Hiicke! rule is satisfied). Examples of "aromatic heterocyclic ring systems" include furanyl, furazanyl, thienyl, pyrrolyl, pyrazolyl, oxazolyl, oxadiazolyl, imidazolyl, isoxazolyl, thiazolyl, thiadiazolyl, isothiazolyl, pyridyl, pyrimidinyl, pyridazinyl, pyrazinyl and triazinyl with said ring attached through any available carbon or nitrogen. For example, when the aromatic heterocyclic ring is furanyl, it can be 2-fiiranyI or 3-furanyl, for pyrrolyl, the aromatic heterocyclic ring is 1-pyrrolyl, 2-pyrrolyl or 3-pyrrolyl, for pyridyl, the aromatic ring is 2-pyridyl, 3-pyridyl or 4-pyridyl and similarly for other aromatic heterocyclic rings. The term "nonaromatic heterocyclic ring system" denotes fully saturated heterocycles as well as partially or fully unsaturated heterocycles where the Httckel rule is not satisfied by any of the rings in the ring system. The heterocyclic ring systems can be attached through any available carbon or nitrogen by replacement of a hydrogen on said carbon or nitrogen.
One skilled in the art will appreciate that not all nitrogen containing heterocycles can form TV-oxides since the nitrogen requires an available lone pair for oxidation to the oxide; one skilled in the art will recognize those nitrogen containing heterocycles which can form TV-oxides. One skilled in the art will also recognize that tertiary amines can form TV-oxides. Synthetic methods for the preparation of A^-oxides of heterocycles and tertiary amines are very well known by one skilled in the art including the oxidation of heterocycles and tertiary amines with peroxy acids such as peracetic and m-chloroperbenzoic acid (MCPBA), hydrogen peroxide, alkyl hydroperoxides such as r-butyl hydroperoxide, sodium perborate, and dioxiranes such as dimethydioxirane. These methods for the preparation of TV-oxides have been extensively described and reviewed in the literature, see for example: T. L. Gilchrist in Comprehensive Organic Synthesis, vol. 7, pp 748-750, S. V. Ley, Ed., Pergamon Press; M. Tisler and B. Stanovnik in Comprehensive Heterocyclic Chemistry, vol. 3, pp 18-20, A. J.

The total number of carbon atoms in a substituent group is indicated by the "C,-C;" prefix where i and j are numbers from 1 to 11. For example, Cj-C3 alkylsulfonyl designates methylsulfonyl through propylsulfonyl; C2 alkoxyalkyl designates CH3OCH2; C3 alkoxyalkjd designates, for example, CH3CH(OCH3),

18
CH3OCH2CH2 or CH3CH2OCH2; and C4 alkoxyaikyl designates the various isomers of an alkyl group substituted with an alkoxy group containing a total of four carbon atoms, examples including CH3CH2CH2OCH2 and CH3CH2OCH2CH2.

In the above recitations, when a compound of Formula I is comprised of one or more heterocyclic rings, all substituents are attached to these rings through any available carbon or nitrogen by replacement of a hydrogen on said carbon or nitrogen.
When a compound is substituted with a substituent bearing a subscript that indicates the number of said substituents can exceed 1, said substituents (when they exceed 1) are independently selected from the group of defined substituents. Further, when the subscript indicates a range, e.g., (R)i_j, then the number of substituents may be selected from the integers between ii and j inclusive.
When a group contains a substituent which can be hydrogen, for example R4, then, when this substituent is taken as hydrogen, it is recognized that this is equivalent to said group being unsubstituted. When a group is optionally substituted with a substituent, for example with R7, then, when the group is not substituted with that substituent, it is recognized that this is equivalent to said group having a hydrogen substituent.
Compounds used in this invention often can exist as one or more stereoisomers. The various stereoisomers include enantiomers, diastereomers, atropisomers and geometric isomers. One skilled in the art will appreciate that one stereoisomer may be more active and/or may exhibit beneficial effects when enriched relative to the other stereoisomer(s) or when separated from the other stereoisomer(s). (See, e.g., U.S. Provisional Patent Application Serial No. 60/057917 filed September 4,1997, which is hereby incorporated by reference in its entirety.) Additionally, the skilled artisan knows how to separate, enrich, and/or to selectively prepare said stereoisomers.

Compounds of Formula II are known to have a fungicidal mode of action which inhibits the bc\ complex. Methyl (£)-2-[[6-(2-cyanophenoxy)-4-pyrimidinyl]oxy]-a-(methoxyimino)benzeneacetate is described as a bc\ complex inhibitor in Biochemical Society Transactions 1993, 22, 68S. Methyl (£)-a-(methoxyimino)-2-[(2-methylphenoxy)methyl]benzeneacetate is described as a bc\ complex inhibitor in Biochemical Society Transactions 1993, 22, 64S. (£)-2-[(2,5-
Dimemylphenoxy)memyl]-a-(methoxyuTiino)-Mmethylbenzeneacetamide is described asa&ci complex inhibitor in Biochemistry and Cell Biology 1995,55(3), 306-311.
The be i complex is sometimes referred to by other names in the biochemical literature, including complex III of the electron transfer chain, and ubihydroquinonexytochrome c oxidoreductase. It is uniquely identified by the Enzyme Commission number ECl. 10.2.2. The bc\ complex is described in, for example, J. Biol Chem. 1989, 264,14543-38; Methods Enzymol 1986,126, 253-71; and references cited therein. The Sterol Biosynthesis Inhibitor Fungicides
The class of sterol biosynthesis inhibitors includes DMI and non-DMI compounds, that control fungi by inhibiting enzymes in the sterol biosynthesis pathway. DMI fungicides have a common site: of action within the fungal sterol biosynthesis pathway; that is, an inhibition of demethylation at position 14 of lanosterol or 24-methylene dihydrolanosterol, which are precursors to sterols in fungi. Compounds acting at this site are often referred to as demethylase inhibitors, DMI fungicides, or DMIs. The demethylase enzyme is sometimes referred to by other names in the biochemical literature, including cytochrome P-450 (14DM). The demethylase enzyme is described in, for example, J. Biol. Chem. 1992, 267,13175-79 and references cited therein. DMI fungicides fall into several classes: triazoles, imidazoles, pyrimidines,

piperazines and pyridines. The triazoles includes bromuconazole, cyproconazole, difenoconazole, diniconazole, epoxiconazole, fenbuconazole, fluquinconazole, flusilazole, flutriafol, hexaconazole, ipconazole, metconazole, penconazole, propiconazole, tebuconazole, tetraconazole, triadimefon, triadimenol, triticonazole and uniconazole. The imidazoles include clotrimazole, econazole, imazalil, isoconazole, miconazole and prochloraz. The pyrimidines include fenarimol, nuarimol and triarimol. . The piperazines include triforine. The pyridines include buthiobate and pyrifenox. Biochemical investigations have shown that all of the above mentioned fungicides are DMI fungicides as described by K. H. Kuck, et al. in Modern Selective Fungicides -Properties, Applications and Mechanisms of Action, Lyr, H., Ed.; Gustav Fischer Verlag: New York, 1995, 205-258.
The DMI fungicides have been grouped together to distinguish them from other sterol biosynthesis inhibitors, such as, the morpholine and piperidine fungicides. The morpholines and piperidines are also sterol biosynthesis inhibitors but have been shown to inhibit later steps in the sterol biosynthesis pathway. The morpholines include aldimorph, dodemorph, fenpropimorph, tridemorph and trimorphamide. The piperidines include fenpropidin. Biochemical investigations have shown that all of the above mentioned morpholine and piperidine fungicides are sterol biosynthesis inhibitor fungicides as described by K. H. Kuck, et al. in Modern Selective Fungicides -Properties, Applications and Mechanisms of Action, Lyr, H., Ed.; Gustav Fischer Verlag: New York, 1995, 185-204. Synergistic Effects
Fungicides that effectively control plant fungi, particularly wheat powdery mildew {Erysiphe graminis) and wheat foot rot {Pseudocercosporella herpotrichoides), are in constant demand by growers. Combinations of fungicides are often used to facilitate disease control and to retard resistance development. Mixtures of fungicides may provide significantly better disease control than could be predicted based on the activity of the individual components. This synergism has been described as "the cooperative action of two components of a mixture, such that the total effect is greater or more prolonged than the sum of the effects of the two (or more) taken independently" (see Tames, P. M. L., Neth. J. Plant Pathology, (1964), 70, 73-80). It has been demonstrated that compositions containing compounds of Formula la and Formula Ha; Formula la and flusilazole; Formula la and tebuconazole; and Formula la, Formula Ila and flusilazole exhibit synergistic effects.
The presence of a synergistic effect between two active ingredients is established with the aid of the Colby equation (see Colby, S. R. In Calculating Synergistic and Antagonistic Responses of Herbicide Combinations, Weeds, (1967), 15, 20-22):

21

Ax B
p=A+B-
100
Using the methods of the Colby, the presence of a synergistic interaction between two active ingredients is established.by first calculating the predicted activity, p, of the mixture based on activities of the two components applied alone. If p is lower than the experimentally established effect, synergism has occurred. In the equation above, A is the fungicidal activity in percentage control of one component applied alone at rate x. The B term is the fungicidal activity in percentage control of the second component applied at rate y. The equation estimates p, the fungicidal activity of the mixture of A at rate x with B at rate y if their effects are strictly additive and no interaction has occurred.
The Colby equation for a three way mixture is

p = A + B + C+ AxBxC . 10000
(A x B) + (A x O + (B x C) 100
In this application, fungicidal activities provided by compositions of Formula la, Formula Ha, flusilazole and tebuconazole alone are compared with that of compositions of the compounds of Formula la and Formula Ha together, compositions of the compounds of Formula la and flusilazole together, compositions of the compounds of Formula la and tebuconazole together, and compositions of the compounds of Formula la, Formula Ha and flusilazole together. Based on the description of synergism developed by Colby, compositions of the present invention are considered to be synergistically useful. Accordingly, this invention provides an improved method of combating fungi, such as wheat powdery mildew {Erysiphe graminis), wheat leaf rust {Puccinia recondita), wheat foot rot {Pseudocercosporella herpotrichoides) and/or wheat glume blotch {Septoria nodorum) in crops, especially cereals.

Synthesis of Compounds of Formula I
The compounds of Formula I where D is O can be prepared as described in International Patent Application WO 94/26722 and as shown in Scheme 1.
An anthranilic acid (2-aminobenzoic acid) of Formula 1 is condensed with an isothiocyanate of Formula R!-NCS to form the 2-thioquinazolinedione of Formula 2. This condensation is preferably performed in the presence of a base such as triethylamine. S-Methylation of this compound affords the 2-methylthio-4(3H)-quinazolinone of Formula 3.
For the introduction of the R2O group, the 2-methylthio-4(3//)-quinazolinone of Formula 3 is treated with a mixture of a base, for example sodium hydride, in R2OH solvent. The reaction mixture is stirred at a temperature from about 0 °C to 120 °C for 1-120 hours. The desired 2-R2O-4(3H)-quinazoIinone can be isolated from the reaction mixture by extraction into a water-immiscible solvent, and purified by chromatography or recrystallization. Similar synthetic procedures are described in U.S. 3,755,582, incorporated herein by reference.

Scheme 1
Anthranilic acids of Formula 1 are known or can be prepared by known methods. For example see, March, J. Advanced Organic Chemistry; 3rd ed., John Wiley: New York, (1985), p 983. The isothiocyanates of Formula Rl-NCS can be prepared from the corresponding amine by treatment with thiophosgene as known in the art. For example, see*/. Heterocycl Chem.t (1990), 27,407.
6-Iodo-3-propyl-2-propyloxy-4(3/0-qumazolinone, Formula la, is a compound of Formula I where D is O, R1 is propyl, R2 is propyl, R3 is iodine fixed in the 6 position and R4 is hydrogen.

28
Synthesis of Compounds of Formula II
Compounds of Formula II where Q is Q-l and X is OR11 can be prepared as described in International Patent Application WO 95/14009 by treating a compound of Formula 4 with an appropriate alkyl transfer reagent in an inert solvent with or without additional acidic or basic reagents or other reagents (Scheme 2). Suitable solvents are selected from the group consisting of polar aprotic solvents such as acetonitrile, dimethylformamide or dimethylsulfoxide; ethers such as tetrahydrofuran, dimethoxyethane, or diethyl ether; ketones such as acetone or 2-butanone; hydrocarbons such as toluene or benzene; and halocarbons such as dichloromethane or chloroform.
Scheme 2

For example, compounds of Formula II where Q is Q-l and X is OR1* can be prepared by the action of diazoalkane reagents of Formula 5 such as diazomethane (V = H) or trimethylsilyldiazomethane (V = (CH3)3Si) on of Formula 4 (Method 1). Use of trimethylsilyldiazomethane requires a protic cosolvent such as methanol. For examples of these procedures, see Chem. Pharm. Bull., (1984), 32, 3759.
As indicated in Method 2, compounds of Formula II where Q is Q-l and X is OR1 ] can also be prepared by contacting compounds of Formula 4 with alkyl

29
trichloroacetimidates of Formula 6 and a Lewis acid catalyst. Suitable Lewis acids include trimethylsilyl triflate and tetrafluoroboric acid. The alkyl trichloroacetimidates can be prepared from the appropriate alcohol and trichloroacetonitrile as described in the literature (J. Danklmaier and H. Honig, Synth. Commun., (1990), 20, 203).
Compounds of Formula II where Q is Q-l and X is OR1} can also be prepared from compounds of Formula 4 by treatment with a trialkyloxonium tetrafluoroborate (i.e., Meerwein's salt) of Formula 7 (Method 3). The use of trialkyloxonium salts as powerful alkylating agents is well known in the art (see U. SchoTlkopf, U. Groth, C. Deng, Angew. Chem., Int. Ed EngL, (1981), 20, 798).
Other alkylating agents which can convert compounds of Formula 4 to compounds of Formula II where Q is Q-1 and X is OR1 * are dialkyl sulfates such as dimethyl sulfate, haloalkyl sulfonates such as methyl trifluoromethanesulfonate, and alkyl halides such as iodomethane and propargyl bromide (Method 4). These alkylations can be conducted with or without additional base. Appropriate bases include alkali metal alkoxides such as potassium terf-butoxide, inorganic bases such as sodium hydride and potassium carbonate, or tertiary amines such as triethylamine, pyridine, l,8-diazabicyclo[5.4.0]undec-7-ene (DBU), and triethylenediamine. See R. E. Benson, T. L. Caims, J. Am. Chem. Soc, (1948), 70,2115 for alkylation examples using agents of this type.
Compounds of Formula II where Q is Q-1 and X is OR11 can also be prepared by reaction of Formula 8 compounds with alkali metal alkoxides (R1 ^"M"1") (Scheme 3). The leaving group Lg1 in the amides of Formula 8 are any group known in the art to undergo a displacement reaction of this type. Examples of suitable leaving groups include chlorine, bromine, and sulfonyl and sulfonate groups. Examples of suitable inert solvents are dimethylformamide or dimethylsulfoxide.
