In plastic flowerpots having a diameter of 6 cm, one cucumber (variety: Sagami Hanshiro) was grown per one flowerpot, and to the young plants at 1.5 leaf stage, the chemicals obtained by diluting the respective wettable powders of the compounds (1) shown in Table 1 prepared as in Example 3 to 500 ppm with water containing a surfactant (0.01%) were sprayed in an amount of 20 ml per one flowerpot, respectively.
After spraying, the cucumbers were grown in a glass greenhouse for 2 days, and then zoosporangia of Pseudoperonospora cubensis collected from infected leaves were sprayed uniformly to the back surfaces of the plant leaves to be inoculated thereinto.
After inoculation, the cucumbers were kept in a dark place at 20.degree. C. for 2 days and grown in a glass greenhouse for 5 days, and the degree of lesion of downy mildew (cucumber) appeared on the first leaves was examined.
The fungicidal effect was evaluated by using 6 ranks as compared with the degree of lesion in the non-treated district (0: all area is infected, 1: lesion area is about 60%, 2: lesion area is about 40%, 3: lesion area is about 20%, 4: lesion area is 10% or less and 5: no lesion is observed).
The results are shown in Table 6.
