If farmers want to get a good harvest, they should beware of high incidence of diseases and insect pests in this season. Powdery mildew is rampant in summer. This disease lasts for a long time, is difficult to cure, and has a high degree of infection. it will seriously affect plant photosynthesis and normal metabolism, resulting in a reduction in production, which will erode your painstaking efforts. So today we will discuss the prevention and cure of powdery mildew.

Cause and consequence of the disease

Powdery mildew is caused by powdery mildew fungi, which is a common plant disease in the garden. Rain Water increased in summer, the temperature increased, the dry and wet changes of the soil were more frequent, and suitable environmental factors led to the entry of powdery mildew.
