　　On July 14–15, the National Agricultural Technology Extension Center convened a consultation meeting in Yinchuan, Ningxia, to discuss the forecast for the occurrence trends of major autumn grain diseases and pests in 2022. The meeting featured exchanges on… Corn The early‑stage dynamics and characteristics of major diseases and pests affecting mid‑ and late‑season rice and potatoes were examined, with particular emphasis on analyzing the baseline levels of pest and disease incidence in autumn grain crops and prevailing meteorological trends, thereby enabling an assessment of the second half of the year. Corn Trends in the occurrence of major diseases and pests affecting mid- to late-season rice and potatoes.
　　Consultation and analysis indicate that it is expected to Corn In the mid-to-late stages, pest and disease outbreaks were generally severe, affecting a total of 810 million mu‑times, with insect pests accounting for 530 million mu‑times and diseases for 280 million mu‑times. Migratory pests such as the fall armyworm, the third-generation armyworm, and the cotton bollworm have… Corn Production faces significant threats, with diseases such as blast, brown spot, and southern rust occurring heavily in certain localized areas. Overall, pest and disease pressures on mid- to late-season rice are moderate to severe, affecting 900 million mu‑times; of these, pests account for 620 million mu‑times and diseases for 280 million mu‑times. Brown planthopper, stem borer, and sheath blight pose a high risk of severe outbreaks in South China, Southwest China, the Jiangnan region, the middle and lower reaches of the Yangtze River, and the Jianghuai rice-growing area, while the rice leafroller and rice blast are expected to occur at moderate to severe levels. Late blight of potatoes is likely to be locally severe in the major production areas of Northeast China, Northwest China, and North China, affecting 7.8 million mu.
　　The meeting called for measures to address the fall armyworm, the Asian corn borer, the two-migration rice pests, and rice blast disease, Corn Faced with the grave and recurring threat of severe outbreaks of diseases and pests such as southern rust, northern corn leaf blight, and potato late blight, the national monitoring and forecasting system must further elevate its strategic vision, clarify responsibilities, and strengthen its sense of accountability. It should focus on critical periods, key regions, and pivotal links, sparing no effort to ensure robust monitoring and early warning, thereby providing solid technical support for securing a bumper autumn grain harvest. At the same time, it is essential to vigorously implement and institutionalize monitoring and forecasting protocols, accelerate the construction of regional stations within the monitoring network, and actively upgrade and modernize monitoring equipment, so as to enhance the efficiency and effectiveness of grassroots monitoring and surveys, laying a strong foundation, establishing a robust platform, and paving the way for leapfrog development in the field of monitoring and forecasting.
　　Technical personnel responsible for monitoring and forecasting in the 29 provinces, autonomous regions, and municipalities that are the nation’s major autumn grain-producing areas, along with experts from research and educational institutions such as the Institute of Plant Protection of the Chinese Academy of Agricultural Sciences, Nanjing Agricultural University, the National Meteorological Center, and Nanjing University of Information Science & Technology, attended the meeting. Wang Ge, Deputy Director of the National Agricultural Technology Extension Center, and Chai Yudong, a member of the Party Leadership Group and Chief Economist of the Agriculture and Rural Affairs Department of the Ningxia Hui Autonomous Region, also attended the meeting and delivered remarks.
