The risk of sudden disaster of diseases and pests in late rice requires strict prevention and control by the Ministry of Agriculture.

Since the beginning of autumn, the temperature in the middle and lower reaches of the Yangtze River, Jiangnan and South China is more than 1 ℃ higher than normal. The climate condition of "not cool in late autumn" is very beneficial to the occurrence and damage of rice pests. There is a risk of sudden disaster in some double cropping late rice in South China and Jiangnan and some single cropping late rice in the middle and lower reaches of the Yangtze River. Therefore, the prevention and control of diseases and insect pests can not be relaxed in the later stage.

According to the monitoring of the national network for major crop diseases and pests and the field investigation of experts organized by the Ministry of Agriculture, the current number of rice planthopper 100 bugs in double cropping late rice areas in South China and Jiangnan is generally 300 million, and about 20% of the fields reach 1000 million 2000. The number of individual uncontrolled fields reached more than 10,000, of which 200 million adults were short-winged adults. The number of 100 clumps of single cropping late rice in the middle and lower reaches of the Yangtze River and Jianghuai is generally less than 300. the number of 100 clumps in the observation area reached 1000 million 2000, with a weekly increase of 50%, of which the percentage of short-winged adults accounted for about 20%. The number of residual insects of rice leaf roller in most double-cropping late rice producing areas was higher than that in the same period last year, generally more than 1000 per mu, and as high as 4000 million in Jiangxi, Hunan and other areas.

In view of this grim situation, the Ministry of Agriculture requires the agricultural departments at all levels in the relevant regions to continue to do a good job in the prevention and control of diseases and pests of late rice and strive to ensure a bumper harvest. First, strengthen monitoring and early warning. Comprehensively carry out a general survey of the insect situation, so that "the bottom number is clear and the situation is clear", accurately grasp the dynamics of occurrence and development, define key prevention and control fields and key prevention and control periods; second, strengthen emergency prevention and control. Give prominence to key areas and reissue land blocks, take measures that combine professional unified prevention and control with mass prevention and control, timely carry out emergency prevention and control, and strictly prevent disasters; third, strengthen supervision and inspection. Strictly implement the supervision and inspection system of piecewise supervision and inspection, organize itinerant guidance of experts, and ensure that prevention and control measures are in place and technical measures are implemented in the field.
