Amino-acid amide derivatives, agricultural or horticultural fungicides, and method for producing the same

�FIELD OF THE INVENTION!
The present invention relates to an amino-acid amide derivative as well as to an agricultural or horticultural fungicide containing the same as an active ingredient. The present invention also relates to a process for preparing the same.
�BACKGROUND OF THE ART!
Amino-acid amide derivatives have been disclosed as intermediates for medicines in Japanese Patent Application, First Publication Nos. Sho 56-8352 and Sho 62-89696. However, these documents fail to disclose the utility of the amino-acid amide derivatives. Although Japanese Patent Application First Publication Nos. Hei 3-5451, Hei 3-153657, Hei 4-230652, Hei 4-230653. Hei 4-283554, Hei 4-308507, and Hei 4-338372 disclose that some amino-acid amides are useful for biocides, the compounds disclosed in these documents are different from the amino-acid amide derivatives according to the present invention.
�DISCLOSURE OF THE INVENTION!
The present inventors have synthesized various amino-acid amide derivatives and have carried out extensive research in connection with their effects on the physiological activities of fungi. As a result, we have found that the compounds according to the present invention exhibit a broad spectrum of anti-fungal activity especially against cucumber downy mildew, grape downy mildew, and tomato late blight, and at the same time they do not hinder desirable plant growth.

The agricultural or horticultural fungicide according to the present invention is a composition containing an amino acid amide derivative represented by Formula �I! as an active ingredient. In the case where the compounds according to the present invention are employed as an agricultural or horticultural fungicide, the compounds acting as the active ingredient can be formulated appropriately, depending on the purpose. The active ingredient is usually diluted in an inert liquid or a solid carrier, and a surfactant or the like is added thereto, if necessary. The mixture is then formulated in a known manner into, for example, a fine powder, a wettable powder, an emulsifiable concentrate, granules, or the like.
Suitable examples of carriers employed in the formulation are solid carriers such as talc, bentonite, clay, kaolin, diatomaceous earth, white carbon, vermiculite, slaked lime, siliceous sand, ammonium sulfate, urea, or the like: and liquid carriers such as isopropyl alcohol, xylene, cyclohexanone, methylnaphthalene, and the like.

TEST EXAMPLE 2
Test on the Effect of Treating Infection by Cucumber Downy Mildew (Pseudoperonospora cubensis)
Cucumber seeds (variety: "Sagami hanjiro") were sown at a rate of 10 seeds each in a square PVC (polyvinyl chloride) pot, wherein each side is 9 cm wide. The seeds were allowed to grow in a greenhouse, for 7 days, to the cotyledonous stage. The seedlings were inoculated with a spore suspension of cucumber downy mildew (Pseudoperonospora cubensis) fungi and then placed in a moist chamber at 22.degree. C. for 24 hours. After drying in the air, a wettable powder prepared as in Formulation Example 2 was diluted with water to a concentration of 500 ppm of the active ingredient, and the aqueous preparation obtained was then applied at a rate of 10 ml per pot to the cucumber seedlings. The seedlings were then placed in a green house. On the seventh day after the inoculation, the extent of lesions was rated in accordance with the standards of evaluation shown in Table 15 in order to secure the effect of treating with the compounds according to the present invention. The results of the test are given in Table 17.

TEST EXAMPLE 3
Test on the Effect of Preventing Infection by Tomato Late Blight (Phytophthora infestans)
One tomato seedling (variety: "Ponterosa") was transplanted into each porcelain pot (diameter: 12 cm) and grown in a greenhouse. A wettable powder prepared as in Formulation Example 2 was diluted with water to a concentration of 500 ppm of the active ingredient, and the aqueous preparation obtained was then applied at a rate of 20 ml per pot to the tomato seedlings at their 6- or 7-leaf stage. After drying in the air, the plant was inoculated with a zoosporangium suspension of tomato late blight (Phytophthora infestans) fungi and then placed in a moist chamber at 22.degree. C. On the fourth day after the inoculation, index of incidence was determined based on the size of the affected area as shown in Table 18. The degree of damage was calculated according to Equation (1) and the index of incidence and the ability to prevent the disease (controlling activity) was calculated according to Equation (2). The results are shown in Table 19.

TEST EXAMPLE 4
Test on the Effect of Preventing Infection by Grape Downy Mildew (Plasmopara viticola)
Grape rooted cuttings (variety: "Kyoho"), each grown from a cutting and pruned, was grown in a porcelain pot (diameter: 12 cm) and maintained in a greenhouse. A wettable powder prepared as in Formulation Example 2 was diluted with water to a concentration of 500 ppm of the active ingredient, and the aqueous preparation obtained was then applied at a rate of 20 ml per pot to the grape seedlings at their 4- or 5-leaf stage. After drying in the air, the plant was inoculated with a zoosporangium suspension of grape downy mildew (Plasmopara viticola) fungi and then placed in a moist chamber at 22.degree. C. for 24 hours. On the seventh day in the greenhouse after the inoculation, the plant was again placed in a moist chamber at 22.degree. C. for 24 hours to cultivate conidiospores. The incidence area where conidiospores grew on each leaf was examined and the incidence index determined according to the standards shown in Table 18. The degree of damage was calculated according to Equation (1) and the incidence index and the ability to prevent the disease (controlling activity) was calculated according to Equation (2). The results of the test are shown in Table 20.
