A substituent may further be introduced into the compound represented by the formula (I) electrophilically or nucleophilically. That is, the compound represented by the formula (I) may be converted into a compound represented by the formula (I-a) or (I-b) as illustrated in the following scheme. Further, it is also possible to radically introduce a substituent into the compound represented by the formula (I). Here, in the formula (I-a), E is an electrophilic reagent, and in the formula (I-b), Nu is a nucleophilic reagent.

n′ and n″ are as defined for the above n.

The reaction to prepare the compound represented by the formula (I-a) varies properly depending upon the electrophile, and the reaction may usually be carried out by a known process or a process in accordance therewith. For example, the above-described Process 1 may be employed. The nucleophilic substitution to prepare the compound represented by the formula (I-b) varies properly depending upon the nucleophile, and the reaction may usually be carried out by a known process or a process in accordance therewith. For example, in a case of an ethyloxy nucleophilic reagent, it is preferred to carry out the reaction in the presence of an inert solvent such as ethanol or dioxane, toluene or octane as the solvent, at a reaction temperature of from 0 to 120° C. for a proper time. The ethyloxy nucleophilic reagent is used in from 0.1 to 10 mol equivalent amount, preferably in from 0.5 to 5 mol equivalent amount.

Further, the compound represented by the formula (I-c) (the compound of the formula (I) wherein X is a halogen atom) may further be converted into a compound represented by the formula (I-d) by removing the halogen substituent, as shown in the following scheme. For the reaction as illustrated by the scheme, catalytic hydrogenation, hydrogen transfer reaction or metal reduction reaction may properly be employed. In the scheme, Hal is a halogen atom.

The catalytic hydrogenation may be carried out in the presence of a catalyst under hydrogen gas atmosphere under normal pressure or under elevated pressure in the presence of a proper solvent. The catalyst to be used may, for example, be a catalyst system having platinum, palladium, rhodium, ruthenium, nickel or iridium. The solvent to be used may, for example, be water, an alcohol (such as methanol or ethanol), ethyl acetate, acetic acid, dioxane, ether, benzene or hexane. In such a case, the catalyst is used in a proportion of from 0.01 to 1.2 mol based on the compound represented by the formula (I-c). Further, the reaction may be carried out in the presence of a base such as triethylamine or sodium hydrogen carbonate. Further, a known reduction reaction may be employed such as hydrogen transfer reaction (e.g. palladium carbon, ammonium formate as a hydrogen source, or sodium dihydrogen phosphate) or a metal reduction reaction (e.g. samarium diiodide).

It shows an excellent controlling effect particularly on powdery mildew of barley and vegetables and rice blast. Further, it is also effective for controlling soil-borne diseases caused by phytopathogenic fungi such as Fusarium, Pythium, Rhizoctonia, Verticillium and Plasmodiophora.

The compound of the present invention may be used in combination with an agricultural adjuvant to formulate various preparations of the fungicide containing the compound, such as a dust, granules, a granular wettable powder, a wettable powder, an aqueous suspension, an oil suspension, a water soluble powder, an emulsifiable concentrate, an aqueous solution, a paste, an aerosol or a microdose dusting powder. The compound of the present invention may be formed into any preparation which is usually used in the agricultural and horticultural field so long as the purpose of the present invention is met. The adjuvant to be used for preparation may, for example, be a solid carrier such as diatomaceous earth, hydrated lime, calcium carbonate, talc, white carbon, kaolin, bentonite, a mixture of kaolinite and sericite, clay, sodium carbonate, sodium bicarbonate, glauber's salt, zeolite or starch; a solvent such as water, toluene, xylene, solvent naphtha, dioxane, acetone, isophorone, methyl isobutyl ketone, chlorobenzene, cyclohexane, dimethylsulfoxide, dimethylformamide, dimethylacetamide, N-methyl-2-pyrrolidone or an alcohol; an anionic surfactant or spreading agent such as a fatty acid salt, a benzoate, an alkyl sulfosuccinate, a dialkyl sulfosuccinate, a polycarboxylate, an alkyl sulfuric ester salt, an alkyl sulfate, an alkyl aryl sulfate, an alkyl diglycol ether sulfate, an alcohol sulfuric ester salt, an alkyl sulfonate, an alkyl aryl sulfonate, an aryl sulfonate, a lignin sulfonate, an alkyl diphenyl ether disulfonate, a polystyrene sulfonate, an alkyl phosphoric ester salt, an alkyl aryl phosphate, a styryl aryl phosphate, a polyoxyethylene alkyl ether sulfuric ester salt, a polyoxyethylene alkyl aryl ether sulfate, a polyoxyethylene alkyl aryl ether sulfuric ester salt, a polyoxyethylene alkyl ether phosphate, a polyoxyethylene alkyl aryl phosphoric ester salt or a salt of a naphthalene sulfonic acid formalin condensate; a non-ionic surfactant or spreading agent such as a sorbitan fatty acid ester, a glycerol fatty acid ester, a fatty acid polyglyceride, a fatty acid alcohol polyglycol ether, an acetylene glycol, an acetylene alcohol, an oxyalkylene block polymer, a polyoxyethylene alkyl ether, a polyoxyethylene alkyl aryl ether, a polyoxyethylene styryl aryl ether, a polyoxyethylene glycol alkyl ether, a polyoxyethylene fatty acid ester, a polyoxyethylene sorbitan fatty acid ester, a polyoxyethylene glycerol fatty acid ester, a polyoxyethylene hardened caster oil or a polyoxypropylene fatty acid ester; vegetable oil or mineral oil such as olive oil, kapok oil, caster oil, palm oil, camellia oil, coconut oil, sesame oil, corn oil, rice bran oil, peanut oil, cotton oil, soy bean oil, rape oil, linseed oil, tung oil or liquid paraffin. A known adjuvant may be selected from adjuvants which are known in the agricultural and horticultural field within a range of not departing from the object of the present invention. Further, an adjuvant which is usually used may also be employed, such as a bulking agent, a thickener, an anti-settling agent, a freeze proofing agent, a dispersion stabilizer, a crop injury-reducing agent or a mildewproofing agent. The blending proportion of the compound of the present invention to the adjuvant is generally from 0.005:99.995 to 95:5, preferably from 0.2:99.8 to 90:10. These formulations can be practically used either as they are or after they are diluted with a diluent such as water to predetermined concentrations and a spreading agent is added thereto as the case requires.

The concentration of the compound of the present invention varies depending upon the crop plant as the object, the way of application, the form of preparation or the dose, and hence cannot be generically determined. However, in the case of foliage treatment, the concentration of the compound as the active ingredient is generally from 0.1 to 10,000 ppm, preferably from 1 to 2,000 ppm. In the case of soil treatment, it is generally from 10 to 100,000 g/ha, preferably from 200 to 20,000 g/ha.

The preparation fungicide containing the compound of the present invention or a diluted product thereof can be applied by an application method which is commonly used, such as spreading (spreading, spraying, misting, atomizing, grain diffusing or application on water), soil application (such as mixing or irrigation) or surface application (such as coating, dust coating or covering). Further, it may be applied also by so-called ultra low volume. By this method, the preparation can contain 100% of the active ingredient.

The fungicide of the present invention may be mixed or used together with e.g. another agricultural chemical such as an insecticide, a miticide, a nematicide, a fungicide, an antiviral agent, an attractant, an herbicide or a plant growth regulator.

Cucumber (cultivar: Suyo) was cultivated in a polyethylene pot having a diameter of 7.5 cm, and when the cucumber reached one and a half-leaf stage, the cucumber was sprayed with a 10 ml of a drug solution having a predetermined concentration of the compound of the present invention by a spray gun. After the drug solution dried, the cucumber was sprayed and inoculated with a conidiospore suspension of fungi of powdery mildew, and the cucumber was kept in a thermostatic chamber at 20° C. From 7 to 11 days after the inoculation, the area of sporogony was examined to determine the controlling index in accordance with the above evaluation standards. As a result, of the above compounds, the compound No. 98 showed effects with a controlling index of 4 or above at a concentration of 500 ppm, and compounds Nos. 1, 5, 7, 9, 55, 74, 90, 92, 93, 102, 103, 123 and 124 showed effects with a controlling index of 4 or above at a concentration of 125 ppm.
