  • Tobacco target spot disease has the characteristics of rapid spread, continuous occurrence and serious harm, which can significantly reduce the yield and quality of tobacco leaves. The disease has become one of the major problems hindering tobacco production, and it is urgent to solve the problem of tobacco target spot disease. This study is based on the concept of green prevention and control, taking healthy cultivation as the core, prediction and forecast as the basis, and system control as the support, emphasizing the balance of nutrients and resistance induction, highlighting the precise use of chemicals. The unified prevention and control with combined prevention and precise control were carried out in Youyang County, Chongqing, and achieved ideal prevention and control results. The results showed that the agronomic traits of tobacco plants in the experimental area at different growth stages were significantly better than those in the conventional treatment area, and the incidence rate and disease index of tobacco target spot disease in the conventional treatment area were always higher than those in the experimental area. The relative control efficiency reached 79.13% at the peak incidence of the disease, and 82.14% at the end of the incidence. The economic benefits of the experimental area were outstanding. Compared with the conventional treatment area, the output value could be increased by 963.28 yuan per 667 m2. It shows that the disease system control scheme can effectively reduce the occurrence of tobacco target spot disease, and has a good comprehensive control effect on virus disease and other leaf spot diseases. The prediction and prediction combined with the actual situation can achieve green, ecological, safe and effective control of disease.

Abstract: Tobacco target spot disease has the characteristics of rapid spread, continuous occurrence and serious harm, which can significantly reduce the yield and quality of tobacco leaves. The disease has become one of the major problems hindering tobacco production, and it is urgent to solve the problem of tobacco target spot disease. This study is based on the concept of green prevention and control, taking healthy cultivation as the core, prediction and forecast as the basis, and system control as the support, emphasizing the balance of nutrients and resistance induction, highlighting the precise use of chemicals. The unified prevention and control with combined prevention and precise control were carried out in Youyang County, Chongqing, and achieved ideal prevention and control results. The results showed that the agronomic traits of tobacco plants in the experimental area at different growth stages were significantly better than those in the conventional treatment area, and the incidence rate and disease index of tobacco target spot disease in the conventional treatment area were always higher than those in the experimental area. The relative control efficiency reached 79.13% at the peak incidence of the disease, and 82.14% at the end of the incidence. The economic benefits of the experimental area were outstanding. Compared with the conventional treatment area, the output value could be increased by 963.28 yuan per 667 m2. It shows that the disease system control scheme can effectively reduce the occurrence of tobacco target spot disease, and has a good comprehensive control effect on virus disease and other leaf spot diseases. The prediction and prediction combined with the actual situation can achieve green, ecological, safe and effective control of disease.
