When the composition of the present invention is applied as a whole plant disease control agent, it is appropriate to apply the active ingredient in an amount of usually 1 g to no IOE per 10 are. When diluting and diluting with
07%~0. A range of J% is preferred. In the case of powders, granules, etc., they are usually applied as is without any dilution. These application amounts and concentrations vary depending on the formulation, and also vary depending on other circumstances such as the time of application, location, application method, type and severity of plant disease, and can also vary depending on the type of crop. The concentration may be changed by increasing or decreasing the concentration without being limited to the range.

Next, the effect of controlling plant diseases by the composition of the present invention will be shown using test examples.

Test example 1 Cucumber and disease control effect Fill a plastic pot with sandy loam and grow cucumber (quality:
Sumo Hanpaku) was sown. This was cultivated in a greenhouse to obtain cucumber seedlings with expanded cotyledons. A water-diluted solution of the test drug in the form of a wettable powder prepared according to Formulation Example 2 was sprayed onto the seedlings so that the Vc drug solution was sufficiently attached to the leaves. Cucumber and disease In (k,'5eudoperOnot+ 1+
oracubensis) was inoculated by spraying with a conidial suspension. The plants were kept under 20C humid conditions for 3 days and cultivated under 1.20C fluorescent lamp illumination for 3 days to develop the disease.The disease state was observed and the disease severity was calculated by the following method. That is, depending on the degree of appearance of lesions on the investigated leaves, they were classified into indices of 0, Q, J, /, 2, and e, and the degree of disease severity was calculated using the following formula.

(Incidence index) 0 No bacterial flora or lesions observed on the leaf surface.

Subsequently, the control value was determined from the following formula.Test Example 2 Cucumber Gray Mold Control Effect A plastic pot was filled with sandy loam, and cucumbers (product!olt: Sumo Hanshiro) were sown. This was cultivated in a greenhouse for ♂ days to obtain cucumber seedlings with expanded cotyledons. A water-diluted solution of the test drug in the form of a wettable powder was applied to the foliage until the drug solution was sufficiently attached to the leaf surface. Chemical solution 1
