摘要：

The occurrence and development of cucumber downy mildew (Pseu- doperonospora cubensis) had been observed in the field for three years. In 1987, an observation plot was set, and the disease of cucumber was investigated in large areas. The result shows that diseased cucumber seedings are triflingly injured under cultural condition and climatical factors within the polyethylene film. After the film is uncovered in second ten days of May, temperature and sunlight are suitable for the disease development. The rainfall then is the key factor to the disease epidemy, much rainfall makes the disease epidemic. Hence, this period is the most important for controlling the disease.
