On July 14, the National Agricultural Technology Extension Center convened a national online consultation meeting on the forecast of disease and pest trends for mid- to late-season rice in 2020. The meeting reviewed and analyzed the current baseline levels of rice diseases and pests, cultivation conditions, climatic factors, and other relevant circumstances, and assessed the projected trends for major diseases and pests affecting mid- to late-season rice in the second half of the year—particularly the “two‑migration” pests and the viral diseases they transmit—providing a scientific basis for planning and deploying monitoring and early‑warning efforts and for guiding control measures. Technical personnel from plant protection and quarantine agencies in 19 provinces, autonomous regions, and municipalities directly under the central government—the nation’s major rice‑producing areas—as well as experts from Nanjing Agricultural University, the National Meteorological Center, and other research and educational institutions participated at their respective sub‑venues. Wang Fuxiang, Deputy Director of the National Agricultural Technology Extension Center, and Wang Jianqiang, First‑Level Researcher with the Department of Crop Production Management of the Ministry of Agriculture and Rural Affairs, attended the meeting.
　　The consultation forecasts that major rice diseases and pests will generally occur at a relatively severe level, exceeding last year’s incidence, affecting 980 million mu‑times. Specifically, brown planthopper, stem borer, second-generation stem borer, and sheath blight are expected to range from moderately severe to severe; blast and false smut will be at a moderate level; while the third-generation stem borer and southern rice black-streaked dwarf disease are anticipated to be relatively mild. Other pests such as large stem borer, rice stem fly, and armyworm will occur to some extent in certain rice-growing areas. Bacterial diseases like bacterial leaf blight pose a risk of widespread outbreaks in coastal, riverine, Huai River–adjacent, and the central‑southern regions of Southwest China, while panicle rot is expected to occur to a certain degree in rice‑growing areas of the Yangtze River basin.
　　The meeting emphasized that, given the severe resurgence of diseases and pests in mid- and late-season rice, plant protection agencies at all levels must remain highly vigilant, plan ahead, and make meticulous arrangements to closely monitor pest and disease outbreaks. Building on the outcomes of the national consultation, they should tailor their responses to local conditions and prevailing circumstances, promptly and accurately issue localized forecasts and early warnings, and disseminate this information swiftly through multiple channels—including television, radio, mobile phones, and the internet—to enhance both outreach and implementation. In doing so, they must ensure that pest and disease intelligence plays a decisive role in providing scientifically sound guidance for prevention and control efforts.
