In order to implement the requirements of the Spring Plowing and Preparedness Video Conference and early planning, mobilization and deployment of the 2012 disease prevention and control work, the Ministry of Agriculture held a joint working meeting on the prevention and control of the Southern Rice Black Stripe Dwarf Disease in Guangzhou on February 11 and summarized the prevention and control in 2011. Effective experience, analysis of the occurrence and prevention and control situation in 2012, research and improvement of countermeasures for prevention and control, and arrangements for the deployment of joint prevention and control operations.
Southern rice black-streaked dwarf disease is a malignant virus disease spread by the white-flying migratory locust, and the risk of rice loss in the region is more than 20%. The analysis of the meeting believes that due to the increase of wintering sources of poisons, the increase of transmission media, and the complex farming system, the degree of disease occurrence in 2012 will be heavier than that of the previous year, and an area of ​​nearly 20 million mu is expected to occur throughout the year.
The meeting proposed that the objective of prevention and control of southern rice black-streaked dwarf disease in 2012 is to strive to control the disease-hazardous area within 10 million mu, and the overall regional loss rate should be controlled within 5%, effectively curbing the disease in the southwest and the northern part of the Jiangnan, and the Yangtze River. The middle and lower reaches and the Jianghuai rice region are widespread and efforts are made to ensure the safety of rice production.
Focusing on this goal, the meeting clearly demanded that in the prevention and control strategy, it should persist in moving forward, establish prevention and control, improve joint prevention and control, strengthen administrative promotion, and ensure that all measures are implemented in the household. The agricultural plant protection departments at all levels should comprehensively strengthen the organization and leadership of prevention and control work in accordance with the principles of “relationship management, zoning, and joint prevention and controlâ€; they must adopt uniform standards and methods to systematically develop whitebacked planthoppers and areas with high virus rates. Joint monitoring ensures that the disease does not spread in large areas due to lack of monitoring and early warning, and that the comprehensive prevention and control measures such as sowing of rice seedlings, covering pest control nets, adjusting the sowing date of rice, and rational “muting of the earthworms†shall continue to be firmly established. Grasping the critical period of the seedling stage of rice, vigorously promote the rule of specialization and defense, and strive to improve the effectiveness, efficiency, and effectiveness of prevention and control to ensure that disease prevention and control measures are not in place, leading to outbreaks of disease in large areas; continue to adhere to and improve Expert guidance on zoning, regional governance mechanisms, and strengthening scientific and technological support for disease prevention and control.
In 2011, the joint prevention and control action organized by the Agricultural Plant Protection Department effectively controlled the occurrence of rice black-streaked dwarf disease in southern China. According to preliminary statistics, the annual disease occurrence area is controlled within 4 million mu, which is 78.8% lower than that in 2010.
