[0964] (Evaluation test on cucumber powdery mildew)

[0965] Each fluorine-containing pyrimidine compound prepared in Examples 32 and 36 was dissolved in acetone and diluted to a concentration of 500 ppm. Next, a cucumber leaf disc (20 mm in diameter) was added to the diluted acetone solution to completely wet it, and the cucumber leaf disc was set in a manner that the back of the cucumber leaf disc was in contact with a separately prepared plain agar medium, and it was air-dried. After air-drying, the spore suspension of cucumber powdery mildew was evenly spread on the cucumber leaf disc and allowed to air-dry. Then, the cucumber leaf disc was placed in a thermostat (25°C, illuminated for 12 hours), and the lesion area was investigated after 14 days to calculate the control value. The results are shown in Table 1. In addition, the control value is calculated according to the following formula. In the following formula, "untreated" means that the cucumber leaf disc is only wetted with acetone as the test liquid, and "untreated area" means its partition.
