The growth cycle of cotton is long, and the cultivation agronomy is complex, and its growth process is highly dependent on the natural environment. Factors such as temperature, moisture and soil environment will directly affect the quality of cotton. At the same time, with the change of production mode, the traditional cotton field ecosystem has undergone significant changes, resulting in the increasing frequency and influence degree of diseases and insect pests year by year. Blight, verticillium wilt, cotton bollworm, aphid and other forms of diseases and insect pests pose a great threat to cotton production. It is the key to ensure cotton yield to make clear the characteristics of cotton diseases and insect pests and carry out targeted prevention and treatment.展开更多
