The risk of reoccurrence of major diseases and insect pests in rice panicle stage is relatively high

Since late August, due to the influence of more Rain Water and "not cool in late autumn" in southern rice region, the population density of rice "two migration" pests has increased rapidly, rice blast is still spreading, and the risk of recurrence of major diseases and insect pests at panicle stage is high. In accordance with the arrangements of the Ministry of Agriculture's "Prevention and Control of Diseases and pests to seize the Autumn Grain Harvest Action," various localities have strengthened monitoring and early warning, strengthened unified control and emergency control, and achieved phased results in the prevention and control of rice diseases and insect pests in the south. As of September 9, a total of 896 million mu of major rice diseases and insect pests had been controlled, 1.1 times the occurrence area of 816 million mu. After effective prevention and control, rice planthopper and rice leaf roller actually occurred 207 million mu and 170 million mu, which decreased by 11.6% and 5.8% respectively compared with the same period last year, and the panicle rate of most rice blast was controlled within 1%.

According to the national monitoring network for major crop diseases and pests, the adult peak of rice planthopper in the south of the Yangtze River and the middle and lower reaches of the Yangtze River is obvious recently, and the number of single light insects per day in Hunan, Jiangxi and Zhejiang is more than 1,000; the number of residual insects of rice leaf borer is generally high, generally 3000 to 4000 per mu, an increase of 20% to 30% over the same period last year; rice blast occurred in a total of 42.51 million mu, an increase of 16% over the same period last year.

In view of the severe situation of high risk of recurrent diseases and insect pests in the later stage of rice in South China, the planting Management Department of the Ministry of Agriculture, together with the National Agricultural Technology extension Service Center, organized agricultural plant protection departments at all levels, insisting that "the harvest is less than one day, and the prevention and control work is not relaxed for a day." strengthen monitoring and early warning, fully grasp the dynamics of the occurrence of diseases and insect pests, and scientifically guide the prevention and control work. We should strengthen unified control and emergency prevention, strive to improve the effectiveness, efficiency, and efficiency of prevention and control, strengthen supervision and guidance, ensure that work measures are in place, technical measures are implemented in the fields, and go all out to ensure a bumper harvest.
