Test on curative effect against cucumber downy mildew : Cucumber (cultivars: Suyo) was cultivated in a ~ polyethylene pot having a diameter of 7.5 cm. When cucumber reached the two-leaf stage, a spore suspension of fungi of downy mildew (Pseudoperonospora cubensis) was inoculated. Six hours after the inoculation, 10 ml of a solution obtained from each of test compounds adjusted to - a predetermined concentration was sprayed over cucumber using a spray gun. After keeping the pots in a constant temperature chamber of 22 to 24°C for 6 days, an area of lesion on the first leaf was investigated, and an index of control was determined by the standards for evaluation described above.
