| Abstract: | With different concentration of 70% thiophanate -methyl WP to control cucumber powdery mildew in the field, the result show that it was the high control efficiency to cucumber powdery mildew as it was early stage with 70% thiophanate - methyl WP 525 -630g/hm^2added water 750kg. thiophanate - methyl WP were sprayed three times, the interval was 7 days. The control efficiency was 77.46% - 80. 94% after 7days, and it was safe to cucumber. |
