[0042] Formulation Example 11 10 parts of the composition of the present invention, 0.2 parts of hexamethylene diisocyanate, and 10 parts of xylene are mixed and dispersed in 75.8 parts of water containing 2 parts of polyvinyl alcohol. 2 parts of ethylenediamine are added, and the encapsulation reaction is allowed to proceed while mixing to obtain a preparation.

[0043] Formulation Example 12 A preparation is obtained by grinding and mixing 2 parts of the composition of the present invention, 88 parts of kaolin clay, and 10 parts of talc.

[0044] Next, the effect of the present invention will be demonstrated by test examples.

[0045] Test Example 1 Control trials for cucumber powdery mildew (Podosphaera xanthii) A plastic pot is filled with soil, cucumbers (variety: Sagami Hanshiro) are sown therein, and grown in a greenhouse for 12 days. A formulation obtained in any one of Formulation Examples 1 to 12 is diluted with water to obtain a diluted solution containing 117 ppm of the present compound and 100 ppm of the present component. The diluted solution is applied to the cucumber leaves at 200 L / 1000 ml so that it is sufficiently attached thereto. 2 Spray a suitable amount of the liquid onto the stems and leaves. After spraying, air-dry the plants, and then sprinkle and inoculate them with spores of cucumber powdery mildew (this is the treatment area). On the other hand, cucumbers are grown in the same manner as in the treatment group, except that the diluted solution is not sprayed on the stems and leaves, and spores of cucumber powdery mildew are sprinkled on and inoculated (this is designated as the untreated group). After inoculation, the plants are cultivated for 8 days in a greenhouse at 24°C during the day and 20°C at night, and then the lesion area is examined. From the lesion areas in the treated and untreated areas, the efficacy of the treated area is calculated using [Equation 1]. As a result, the control effect against cucumber powdery mildew can be confirmed in the treated area. [Formula 1] TIFF2025031831000001.tif18140

[0046] Test Example 2 Control trials for tomato leaf mold (Fulvia fulva) Soil is packed into a plastic pot, tomatoes (variety: Patio) are sown therein, and grown in a greenhouse for 3 weeks. A formulation obtained in any one of Formulation Examples 1 to 12 is diluted with water to obtain a diluted solution containing 117 ppm of the present compound and 100 ppm of the present component. The diluted solution is applied to the tomato leaf surface in an amount of 200 L / 1000 ml so that it is sufficiently adhered thereto.2 A suitable amount of the liquid is sprayed on the stems and leaves. After spraying, the tomatoes are air-dried and then inoculated with a water suspension of tomato leaf mold spores (this is the treatment area). On the other hand, tomatoes are grown in the same manner as in the treatment group, except that the diluted solution is not sprayed on the stems and leaves, and then inoculated with a water suspension of spores of tomato leaf mold fungus by spraying (this is designated as the untreated group). After inoculation, the plants are placed in a greenhouse at 24°C during the day and 20°C at night under humid conditions for 3 days, then cultivated in the greenhouse for 14 days, after which the lesion area is examined. From the lesion areas in the treated and untreated areas, the efficacy of the treated area is calculated using [Equation 1]. As a result, the control effect against tomato leaf mold can be confirmed in the treated area. [Industrial Applicability]
