were sown and grown in a greenhouse for 60 days. These seedlings were inoculated by spraying a spore suspension of the potato anti-disease fungus. After inoculation, the plants were grown for 1 day at 20° C. under humid conditions, and the test compound was made into an emulsion according to Formulation Example 2, diluted with water to a predetermined concentration, and sprayed on the leaves so that it would adhere sufficiently to the leaf surface.
