| Abstract |
|
This research was performed to examine the effects of mixed espil and copper hydroxide for powdery mildew prevention on cucumber, tomato and pepper. On prevention effect for powdery mildew on cucumber, results revealed that mixed espil and copper hydroxide with a ratio of 4 : 1, disease incidence rate was 18.9% and prevention effect was 69.9%. Another treatment with a ratio of 8 : 1 showed an disease incidence rate of 18.1% and prevention effect of 71.1%, thus, showed great effectiveness. For powdery mildew on tomato, espil and copper hydroxide were mixed using the ratio 4 : 1, results showed an disease incidence rate of 12.4% and prevention effect of 85.3%. Treatment using the ratio of 8 : 1, results showed an disease incidence rate of 14.3% and prevention effect of 83.0%, thus, showed great effectiveness. For powdery mildew on redpepper, espil and copper hydroxide were mixed using the ratio of 4 : 1 with results showed disease incidence rate of 17.7% and prevention effect of 83.0%. From the results, this treatment is the most effective with the lowest attack rate and highest prevention effect. Deducing from the study, it was found out that using mixed espil and copper hydroxide using the ratios 4 : 1 or 8 : 1 are the most effective method for powdery mildew prevention. Mixed ratio of 4 : 1 or 8 : 1 was most effective for preventing powdery mildew on cucumber and tomato, while the espil and copper hydroxide ratio of 4 : 1 was the most effective method for powdery mildew prevention on pepper. |
