The present inventors synthesized a large number of azole derivatives and conducted extensive studies on their practicality in order to develop a low-toxic, safe, and versatile fungicide. As a result, it has been found that the azole derivative represented by the above general formula [] has extremely excellent properties as a fungicide for agricultural and horticultural use. Until now, it was disclosed in Japanese Patent Application Laid-Open No. 52-1979 that esters, anilides and imines of 1,2,4-triazol-1-yl fatty acids could be used as fungicides for agricultural and horticultural purposes.
It is known from the publication No. 27767. However, the amidines provided by the present invention are novel compounds whose composition has not yet been described. Furthermore, the bactericidal activity of these compounds of the present invention is significantly superior to that of conventionally known compounds. That is, the compounds of the present invention have a wide range of antibacterial activity and exhibit control effects against a wide range of plant diseases, but are particularly effective against mildew and powdery mildew of cereals, beans, vegetables, or fruit trees. Furthermore, the compounds of the present invention have almost no phytotoxicity to useful crops, and can be used safely without toxicity to animals or fish. Furthermore, when the compound of the present invention is reacted with alcohols and thiols, 1,2,4-triazole-1, which is an excellent bactericidal agent, is
The compound of formula [] is also an important synthetic intermediate because it can be easily derived into -yl fatty acid isoanilides and isothioanilides. In addition, since the compound of formula [] contains a 1,2,4-triazole ring and in some cases an imidazole ring,
It can also be used in the form of an inorganic acid salt, an organic acid salt, or a metal complex salt. In addition, the compound of formula [] may have geometric isomers because it has a -C=N- double bond, and stereoisomers such as optical isomers depending on the type of A, but the present invention is intended to include all single isomers or mixtures thereof in any ratio. The compound of formula [] of the present invention can be produced by the method of the following reaction formula (a) or (b). Reaction formula (a) In the general formula [], X, n, Y and A have the same meanings as above, and Hal represents a halogen atom. The compound of the general formula [] is the compound of the general formula []
Since it has an azole group like the compound described above, it can also be used in the form of inorganic acid salts, organic acid salts, and metal complex salts. The compound of formula [] can be easily produced by the reaction of imidoyl halides obtained by the reaction of halofatty acid anilides with phosphorus pentahalides and azoles. The compound of formula [] is 1,
It is a 2,4-triazole and can be easily produced by known methods. It is usually preferable to use an organic solvent when reacting the compound of formula [] with the compound of formula [] according to reaction formula (a). Examples of organic solvents include hydrocarbons such as benzene and toluene, halogenated hydrocarbons such as chloroform, carbon tetrachloride, and dichloroethane, ethyl ether,
Ethers such as tetrahydrofuran, esters such as methyl acetate and ethyl acetate, ketones such as acetone and methyl isobutyl ketone, nitriles such as acetonitrile and propionitrile, amides such as dimethylformamide and N-methylformamide, and dimethyl sulfoxide. etc. can be used. The acid binder does not necessarily need to be used because the compounds of formulas [], formulas [], and [] are bases, but if necessary, organic amines such as triethylamine and pyridine, or inorganic bases such as potassium carbonate may be used. can be used. Further, the compound of the formula [] can be used in advance by converting it into a sodium salt or potassium salt with metallic sodium, sodium amide, sodium hydride, or the like. The reaction can be carried out at any temperature from cooling to the boiling point of the solvent, but usually a temperature from 0°C to about 100°C under ice-water cooling, preferably from room temperature to 85°C. The reaction time varies depending on the solvent used, reaction temperature, etc., but is usually completed within 3 hours. After completion of the reaction, when an acid binder is used, the salts of the acid binder precipitated in the reaction solution are separated and the solvent of the solution is distilled off to obtain the compound of the present invention.
Further, depending on the case, the desired product can be obtained by adding a solvent such as benzene, chloroform, ether or tetrahydrofuran and water, separating the organic layer, and distilling off the organic solvent. Example 1 shows a method for producing the compound of the present invention according to reaction formula (a). Reaction formula (b) In the general formula [], X, n and A have the same meanings as above, and Hal represents a halogen atom. Since the compound of the general formula [] has a 1,2,4-triazole group like the compound of the general formula [], it can also be used in the form of an inorganic acid salt, an organic acid salt, or a metal complex salt.

It is usually preferable to use an organic solvent in the reaction between the compound of formula [] and the compound of formula [] according to reaction formula (b). Examples of organic solvents include hydrocarbons similar to those produced by reaction formula (a), halogenated hydrocarbons, ethers, esters, ketones, nitriles,
Amides, dimethyl sulfoxide, etc. can be used. Since the compounds of formula [], formula [], and formula [] are bases, acid binders do not necessarily have to be used, but if necessary, amines and inorganic bases as described in reaction formula (a) can be used. Alternatively, the compound of formula [] can be used in advance in the form of sodium salt or potassium salt. The reaction can be carried out at any temperature from cooling to the boiling point of the solvent. Usually, the reaction temperature is selected from 0°C to about 100°C under ice-water cooling, preferably from 0°C to 85°C. Although the reaction time varies depending on the solvent used, reaction temperature, etc., the reaction is relatively quick and is usually completed within one hour. Treatment after completion of the reaction can be carried out according to the method described in reaction formula (a). Example 2 shows a method for producing the compound of the present invention according to reaction formula (b). Furthermore, when Y is a nitrogen atom in the compound [ ] of the present invention, the reaction route is shown by reaction formula (a) or (b), but the reaction formula shown below is

66 parts were uniformly mixed and pulverized, water was added and granulated, dried and sieved to obtain granules containing 3% of the active ingredient. Test example 1 Wheat rot disease control test Wheat seedlings in the first true leaf stage grown in clay pots with a diameter of 9 cm in a greenhouse (variety Norin No. 61)
A predetermined concentration diluted solution of a hydrating powder prepared according to Example 5 was sprayed in an amount of 20 ml per three pots. One day later, the summer spores of the wheat rot fungus that had been formed on the wheat leaves were examined using a microscope with a magnification of 150 times, using Tween 20 [Polyoxyethylene (manufactured by Kao Atlas Co., Ltd.)] so that the spore concentration was approximately 50 per field of view. [trade name of sorbitan monolaurate] was suspended in sterile water to which 50 ppm was added, and the suspension was sprayed and inoculated onto leaves sprayed with the drug. After keeping it in a humid room at 20°C overnight, it was transferred to a greenhouse at 20°C to induce disease onset. Ten days after inoculation, the leaves were taken out, the number of infected pedicelium per leaf was investigated, and the control value (%) was calculated using the following formula. In addition, chemical damage to wheat was investigated using the following indicators. The test was conducted using three pots at one concentration, and the average control value (%) was determined. The results are shown in Table 2. Control value (%) = (1 - number of diaspores in the sprayed area / number of diaspores in the untreated area) x 100 Survey indicators for chemical damage 5: Severe, 4: Severe, 3: Many, 2: Little, 1: Slight, 0: None Test Example 2 Powdery mildew prevention test on cucumber Powdery mildew test On the first leaf stage seedlings of cucumber (cultivar Sagami Hanshiro) grown in clay pots with a diameter of 9 cm in a greenhouse,
A predetermined concentration chemical solution of an emulsion prepared according to Example 6 was
After spraying 10 ml and leaving it overnight, a powdery mildew spore suspension was sprayed and inoculated. Ten days after inoculation, the area ratio (%) of powdery mildew lesions on cucumber was investigated, and the control value (%) was calculated using the following formula. Furthermore, chemical damage to cucumbers was investigated using the same criteria as in Test Example 1. The results are shown in Table 2. Control value (%) = (1 - percentage of lesion area in sprayed area/ percentage of lesion area in non-sprayed area) x 100
