What is truly effective is to integrate disease-resistant varieties, agricultural prevention, biological prevention, chemical prevention and other multi-link means to achieve complementary advantages. This "integrated management" idea is completely consistent with the IPM (Integrated Pest Management) concept of modern plant protection, and is also the development direction of disease management in the future (da Silva and Clark, 2013). Secondly, the regional adaptability and feasibility of plant protection measures are extremely important. Some methods that are effective under experimental conditions are difficult for farmers to adopt in time if the cost is high or the operation is complicated, and the actual promotion value is limited. Although these simple technologies seem to be local methods, they are feasible and sustainable in specific situations and are worth promoting according to local conditions. Thirdly, the disease monitoring and early warning system should be improved. By strengthening disease monitoring in production areas, signs of the prevalence of sweet potato root rot can be discovered in time and countermeasures can be taken early. For example, a root rot disease prediction model based on meteorological and soil data is established. When the epidemic risk is predicted to increase, farmers are reminded to make preparations in advance such as pre-harvest water control and lowering storage temperature and humidity to minimize losses (Zhao et al., 2024). Finally, regional cooperation and technical exchanges are also critical. Diseases have no borders, and each production area should share experiences and jointly respond to challenges. For example, Africa can learn storage management and disease-resistant breeding experience from Asia, and Asia can also refer to the practices of the Americas in precision pesticide application and big data monitoring. In recent years, international agricultural research institutions (such as the CIP International Potato Center) have actively promoted global cooperation in the management of sweet potato pests and diseases, hoping to improve the overall prevention and control level through cross-regional promotion of cases and technologies (Zheng et al., 2021). Looking to the future, as the concept of green plant protection is deeply rooted in the hearts of the people and various new technologies are developed, the regional comprehensive management model of sweet potato root rot will continue to improve and have a broader potential for promotion and application. 7 Outlook and Research Suggestions 7.1 Development trend of technology integration and green control Facing complex soil-borne diseases such as sweet potato root rot, future control will develop in the direction of "technology integration" and "green control". Technology integration requires us to break through the limitations of a single discipline and measures and integrate multiple advanced methods for disease management. For example, by combining remote sensing and big data, we can digitally model and accurately monitor the disease pressure of large areas of sweet potato fields. Once it is found that the soil moisture, temperature and other indicators in a certain area are close to the critical value of the root rot epidemic, farmers can be warned in time through mobile terminals to guide them to take measures such as dehumidification and ventilation. This is a new application of digital agricultural technology in plant protection, which is expected to significantly improve the timeliness and pertinence of control (Zheng et al., 2021). Similarly, modern biotechnology and traditional breeding are also merging, and the cultivation of disease-resistant varieties has entered the molecular design breeding stage. Genomic selection and gene editing (CRISPR-Cas, etc.) will shorten the breeding cycle of sweet potato disease resistance, and new and superior varieties with high resistance to root rot may be bred in the next 5-10 years. In addition, the combination of chemical control and biological control is also one of the trends - some new environmentally friendly agents (such as plant-derived essential oils, inducers) mixed with biocontrol agents can produce synergistic effects, which not only expands the antibacterial spectrum, but also reduces the amount of chemical drugs used. The concept of "green control" will run through all aspects of sweet potato disease management. Green control emphasizes ecological regulation and biological measures, supplemented by safe and efficient necessary chemical means. At the same time, it increases investment in the research and development of biological and physical
