The Ministry of Agriculture deploys the prevention and control of major diseases and pests in autumn grain crops

The period from August to September is not only an important period for the formation of autumn grain crop yield, but also a key period for disease and pest control. On July 29, the Ministry of Agriculture held a national on-the-spot meeting on the prevention and control of major diseases and pests of autumn grain crops in Shandong, and proposed that this year, the prevention and control of major diseases and pests of autumn grain crops should strive to control the loss of major diseases and pests of rice and corn within 5%. The damage loss in the general occurrence area of potato late blight was controlled within 5%, and the recurrent area was controlled within 8%, and the coverage rate of specialized unified control reached more than 27%, an increase of 2 percentage points over the previous year.

The meeting pointed out that the occurrence of major diseases and insect pests in autumn grain crops such as rice, corn and potatoes this year was significantly higher than that of last year and perennial years. At present, the number of eggs of corn borer in Northeast and North China is 1.5 times that of the previous year, and the late blight of rice blast in Northeast China and the main potato producing areas in North China are spreading rapidly. It is estimated that the incidence of major diseases and pests in autumn crops will reach 2.3 billion mu, an increase of 5% over the same period last year. Among them, rice "two migratory" pests occurred in South China, Jiangnan, the eastern part of southwest China and the middle and lower reaches of the Yangtze River, and rice blast was prevalent in Northeast, Southwest, South China and some parts of Jiangnan. Corn borer and armyworm occurred moderately to heavy in the northeast and Huang-Huai-Hai corn producing areas, armyworm will still appear concentrated damage locally, and potato late blight will be prevalent in parts of northwest and North China, which will seriously threaten the safety of autumn grain production.

The meeting stressed that the prevention and control of major diseases and pests of autumn grain crops have a tight time and heavy tasks, and agricultural plant protection departments at all levels should fully understand the extreme importance of doing a good job in prevention and control, firmly promote the goal of continuing to increase grain production, and gain a bumper harvest based on disaster resistance. act quickly, pay close attention to implementation, carry out disease prevention and pest prevention and control actions in a strong and orderly manner, and ensure that the best opportunity for prevention and control will not be missed because monitoring and early warning is not in place. To ensure that the lack of prevention and control measures will not lead to large-scale outbreaks of diseases and insect pests, minimize the losses of diseases and insect pests, and win the initiative to win a bumper harvest of autumn grain.

The meeting demanded that agricultural plant protection departments at all levels should adhere to the principles of classified guidance and scientific prevention and control, highlight major crops, major diseases and pests, and key areas, and aim to prevent and control diseases and pests, increase production and income, reduce losses and increase efficiency, focus on monitoring and early warning, unified prevention and control, green prevention and control, and safe use of drugs, extensively mobilize, strengthen service guidance, implement key measures, carry out emergency prevention and control in a timely manner, and vigorously promote specialized unified control. We will effectively improve the effectiveness of prevention and control and resolutely curb the outbreak of diseases and insect pests.

First, it is necessary to strengthen organizational leadership, implement the prevention and control mechanism of "government leadership, territorial responsibility, and joint prevention and control," and give full play to the role of administrative promotion in the mobilization, command and coordination, supervision and guidance of pest prevention and control organizations, so as to ensure the smooth development of prevention and control work.

Second, it is necessary to promote scientific prevention and control, rice planthopper prominently grasp "before and after control" and strictly prevent the outbreak in the later stage; rice leaf roller strictly meet the control standards, focusing on the protection of functional leaves (upper clover); rice blast and potato late blight pay close attention to opening heading and flowering prevention; while corn borer vigorously promote light trapping and bee control, we should focus on "one prevention and double reduction" in the big trumpet period. The armyworm should be combined with investigation and treatment to give prominence to unified prevention and control.

Third, it is necessary to strengthen unified defense rule, give full play to the advantages of professional unified defense rule with good prevention and control effect and high efficiency, increase support, vigorously promote the application of high-efficiency pesticide application machinery, such as self-propelled, stretcher, and flight prevention and navigation operations, and strive to improve the effect of prevention and control and the degree of organization. At the same time, we should give full play to the advantages of green prevention and control of ecology, environmental protection and safety, implement comprehensive management, and constantly improve the scientific level of pest prevention and control.

Fourth, it is necessary to strengthen supervision and guidance, establish a responsibility system for contracting and working in pieces at various levels, organize capable forces to go deep into the production line during the critical period of prevention and control, guide prevention and control work face-to-face and hand in hand, and ensure that prevention and control measures are put in place and prevention and control technology is implemented in the field.
