The National Agricultural Technology Center convened a national consultation meeting in Korla, Xinjiang, to discuss the 2023 outlook for the occurrence of major autumn grain pests and diseases.

　　On July 11–12, the National Agricultural Technology Center convened a consultation meeting in Korla City, Bayingolin Mongol Autonomous Prefecture, Xinjiang, to discuss the forecast for the occurrence trends of major autumn grain pests and diseases nationwide in 2023. The meeting facilitated an exchange of… Corn The early‑stage dynamics and characteristics of major diseases and pests affecting mid‑ and late‑season rice and potatoes were examined, with a focused analysis and assessment of the projected trends for major autumn grain diseases and pests in the second half of the year. Monitoring and early‑warning efforts for autumn grain pests and diseases were planned and deployed. In addition, for the first time, on-site comparative trials of intelligent monitoring equipment for crop diseases and pests were conducted nationwide.
　　Consultation and analysis indicate that it is expected to Corn In the mid-to-late stages, pest and disease incidence was generally moderate to severe, affecting a total area of 830 million mu‑times, including 580 million mu‑times of insect pests and 250 million mu‑times of plant diseases. 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. For mid- to late-season rice, pest and disease pressures are generally elevated, affecting a total of 950 million mu‑times, including 660 million mu‑times of insect pests and 290 million mu‑times of diseases. Brown planthopper, stem borer, and sheath blight are severe in most rice-growing regions, while the rice leafroller and rice blast are at moderate levels. In potato, late blight is moderately prevalent across the major production areas of Northeast, Northwest, and North China, with an affected area of 7.78 million mu.
　　To ensure the effective implementation of the newly released “Technical Parameters and Performance Requirements for Crop Disease and Pest Monitoring Equipment” (Agricultural Industry Standard NY/T 4182-2022), the conference included an on-site comparative testing session. Under the oversight and guidance of an expert evaluation panel chaired by Lu Yanhui, Director of the Institute of Plant Protection at the Chinese Academy of Agricultural Sciences, and with the joint supervision of all participants, 11 intelligent monitoring devices from eight companies were subjected to a series of tests, including assessments of image‑based automatic identification and counting accuracy, pheromone‑based insect‑attracting efficacy, and overall automatic counting precision. Through this on‑site evaluation—characterized by standardized and transparent procedures, rigorous and fair processes, and clear, impartial results—the strengths and limitations of each device were identified, sparking widespread attention and reflection across the entire innovation‑production‑application value chain. This process has also paved the way for a new approach: using real‑world performance as the benchmark for evaluating monitoring equipment, while leveraging technology to guide the market toward healthy, orderly development.
　　The meeting called for focusing on reducing losses and increasing yields, emphasizing the effective implementation of key disaster prevention and mitigation measures such as pest and disease monitoring and early warning, striving to make up for summer losses in the autumn, and ensuring stable grain production throughout the year. In particular, attention should be given to the fall armyworm, the common cutworm, the two‑migratory rice pests, and rice blast disease, Corn In the face of a severe and recurring threat posed by 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 perspective, clarify responsibilities, and strengthen its sense of accountability. It should continue to uphold the fine tradition of fearlessly confronting hardship and challenges, and devote itself wholeheartedly to enhancing monitoring and early‑warning efforts. At the same time, guided by relevant standards and drawing on the results of this field‑based trial of intelligent monitoring equipment, the system should, in accordance with the principles of advanced technology, practical applicability, and real‑world utility, carefully select and configure pest and disease monitoring instruments and equipment, establish robust field‑based monitoring stations, and continue to advance the intelligent, digital, and precision‑oriented development of monitoring and forecasting work.
　　Technical personnel responsible for pest and disease forecasting from 29 provincial plant protection agencies in the nation’s major autumn grain-producing regions, 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 Plant Protection Institute of the Hebei Academy of Agriculture and Forestry, Nanjing University of Information Science & Technology, and the National Meteorological Center, attended the meeting. Xu Shuren, Deputy Secretary of the Party Committee and Secretary of the Commission for Discipline Inspection of the National Agricultural Technology Extension Center; Li Jing, Member of the Party Leadership Group and Deputy Director of the Department of Agriculture and Rural Affairs of the Xinjiang Uygur Autonomous Region; and Badai, Vice Governor of the Bayingolin Mongol Autonomous Prefecture, also attended the meeting and delivered remarks.
