Cucumber is susceptible to Fusarium wilt, which can be prevented by spraying carbendazim solution.

1, lighting

Cucumber likes sunny environment. When rainy days continue to appear, sunny days suddenly appear, and the light is too strong, cucumbers will transpiration a lot, leading to loss of points. The environment is dark, cucumber grows thin, and sufficient light should be ensured every day. When the light is strong in summer, it is necessary to shade the cucumber.
