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

　　On July 11–12, the National Agricultural Technology Extension 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 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, with pests accounting for 580 million mu‑times and diseases for 250 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. For mid- to late-season rice, pest and disease pressures are generally elevated, affecting a total of 950 million mu‑times—660 million mu‑times from pests and 290 million mu‑times from 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 the major potato-producing areas of Northeast, Northwest, and North China, late blight is generally moderate, 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 performance, 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 effectiveness to assess and validate monitoring equipment performance, 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 paid 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 vision, clarify responsibilities, and strengthen its sense of accountability. It should continue to uphold the fine tradition of fearlessness in the face of hardship and adversity, 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 comparative trial of intelligent monitoring equipment, the system should select and deploy pest‑and‑disease monitoring instruments and devices in accordance with the principles of advanced technology, practical applicability, and real‑world utility; establish robust field monitoring stations; and continue to advance the intelligent, digital, and precision‑oriented development of monitoring and forecasting work.
　　Technical personnel from the plant protection agencies of 29 provincial-level regions—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 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 and addressed the gathering.
