All localities have carried out the "Action to Prevent Disease, Control Insects and Seize Autumn Grain Harvest"

At present, the middle and late rice in South China is in an important period of yield formation, and it is also a key period for the prevention and control of major diseases and insect pests. According to the monitoring of the national network for major crop diseases and pests, affected by the weather, the occurrence of major diseases and insect pests in rice is more serious than in the previous year and perennial years. First, the epidemic disease is spreading rapidly.

As of August 25, the total area of rice blast in the middle and lower reaches of the Yangtze River was 37.17 million mu, an increase of 17.7% over the same period last year. The rate of diseased leaves of some medium rice, such as Hunan, Jiangxi and Hubei, reached more than 10%, and the rate of diseased leaves was as high as 30%. The occurrence degree of single cropping rice in the middle and lower reaches of the Yangtze River, such as Jiangsu and Zhejiang, was the most serious in the past decade. Sheath blight occurred more frequently in most rice areas. Second, the migratory pests showed a trend of light in the front and heavy in the second. Affected by the continuous mass migration since June, the occurrence area and density of rice planthopper and rice leaf roller in the south of the Yangtze River and the middle and lower reaches of the Yangtze River have increased sharply, and the occurrence degree in some areas (such as Hunan) is the heaviest since 2008. Third, borer pests occur one after another. The total occurrence area of rice borer in the south of the Yangtze River and the middle reaches of the Yangtze River is 153 million mu.

In view of the resurgence of major diseases and insect pests in middle and late rice, various localities have solidly carried out the "action of preventing and controlling diseases and pests to win a bumper harvest of autumn grain" to resolutely curb the outbreak of diseases and insect pests. First, timely mobilization and deployment. Hunan, Jiangxi, Hubei, Jiangsu, Anhui and other key rice production provinces have successively held on-the-spot meetings on prevention and control and issued guidance documents to make arrangements for the prevention and control of major diseases and pests in middle and late rice. Various localities refine the implementation plan, improve prevention and control measures, implement prevention and control responsibilities, and ensure that the work is carried out in an orderly manner. The second is to strengthen monitoring and early warning. Increase the frequency and intensity of monitoring and investigation, accurately grasp the occurrence dynamics of major rice diseases and insect pests, and timely study and determine the occurrence trend, so as to provide a scientific basis for prevention and control decision-making. At the same time, strict information reporting system, timely release of forecast and early warning information and prevention and control technology to guide farmers to scientific prevention and control. The third is to promote the rule of unified defense. We will give full play to the role of a pilot demonstration base for the integration of professional unified defense rule and green prevention and control, increase support, and strive to improve the organized and scientific level of prevention and control. Hunan finance at all levels invested a total of 75 million yuan to support unified prevention and control and green prevention and control. The total contracted rice control service area reached 18.2 million mu, an increase of 15 percent over the same period last year. Jiangsu provincial finance allocated 38 million yuan to support unified prevention and control. The unified control rate of major rice diseases and pests reached 56 percent, an increase of 5 percentage points over the same period last year. Fourth, carry out supervision and inspection. Since late July, all provinces and autonomous regions have sent five or six supervision and technical guidance groups to go deep into the front line of prevention and control, carry out itinerant supervision and guidance, focus on inspecting the implementation of prevention and control responsibilities and measures, hold technical training, and carry out on-site guidance. Agricultural plant protection departments in various counties and districts have also implemented the contact system for technicians stationed in villages, organized and sent capable forces to go deep into the fields, face-to-face, hand-in-hand to guide farmers in disease prevention and pest control, and effectively improve the arrival rate of prevention and control technology.

Up to now, the total area for the control of major rice diseases and pests is 723 million mu, accounting for 94.5 percent of the total. The recurrence of major diseases and insect pests in middle and late rice has been curbed. Now, there is still some time before the large-scale harvest of middle and late rice. The Ministry of Agriculture requires all localities to have less than one day of autumn grain, not to relax prevention and control, to step up efforts, and to strengthen measures to strive for a good harvest of autumn grain.
