At present, the double-season late rice in South China and Jiangnan is at the heading stage. The rice pests and diseases were moderately occurring, among which the rice planthoppers rose rapidly in the eastern rice region of the south of the Yangtze River, and the insect population of the rice leaf roller in the South China rice area was slightly higher. The insect population of the rice stem borer in the Jiangnan rice area was significantly higher than that of the perennial. Blight is common, and the neck and neck are successively manifested. Rice virus disease and rice bacterial diseases are more harmful in some areas. In the next stage, the rainfall in the eastern part of the Yangtze River is more than normal in the same period of the year, which is conducive to the relocation of the “two-shift†pests and the occurrence of other rice pests and diseases; especially in the high-lying areas of rice planthoppers in northern Fujian, the rice planthoppers should be wary of the outbreak.
Rice pest
1 rice planthopper
Rice planthoppers occur in medium-sized areas in South China and Jiangnan, with an area of ​​35.22 million mu, an increase of 1.6% year-on-year. Since the beginning of September, the rice planthoppers have been monitored in the South China and Jiangnan rice areas, and the species moved into the brown planthoppers. The total amount of migration has decreased by 10.9%. According to local monitoring, the amount of insects in the field is lower than that of the same period of last year. The amount of worms is generally 100-600, and the height of eastern China and coastal areas is 800-1,300. The local fields are 3,000-6,000 heads. The block is over 10,000 heads. Among them, the recent increase in the number of insects in Fujian is relatively fast. For example, the amount of peas in the double-season late-season rice is generally 1,500 to 2,200, and the high is 2,800. Some fields have been “brownâ€.
2 rice leaf roller
Rice leaf roller is generally lighter in southern China and Jiangnan rice areas, with an area of ​​19.14 million mu, a decrease of 2.0% year-on-year. Since the beginning of September, the peaks of rice leaf roller reefs have been monitored in various places. The amount of moths in the field is generally 50-500 heads, and the local high in southern China is 1,000-3,000 heads. The amount of larvae in the field is comparable to that of the same period of the previous year. The rice area in South China is slightly higher. The amount of larval larvae is generally 1,000-8,000 heads, and the number of larvae in southern China is as high as 10,000-40,000 heads. The field leaf rolling rate is generally 0.1% to 3%, the high is 4% to 7%, and the local field in Jiangxi Anyuan is as high as 12%.
3
Chilo suppressalis occurs moderately to heavily in the Jiangnan rice region, with an area of ​​16.05 million mu, an increase of 6.0% year-on-year. According to the monitoring, the Jiangnan rice area has entered the four-generation sorghum egg hatching period, and the field insects are higher than the same period of the year. The larval larvae are generally 500 to 2,500 heads, and the central and southern Hunan and Xiangdong highs are 3,000-8,000 heads. The local field has over 30,000 heads. The rate of heart failure caused by damage in the field is generally 0.1% to 1.2%, and the high is 3.8% to 8.6%.
Rice disease
1 sheath blight
Sheath blight is generally biased in southern China and Jiangnan rice areas, with an area of ​​37.7 million mu, a year-on-year decrease of 4.4%. At present, sheath blight is in the vertical expansion stage, the disease rate is generally 4% to 27%, and the high is 35% to 60%; the disease rate is generally 15% to 40%, and the high is 45% to 78%. Ji'an, Yihuang and other local fields in southern Anhui are as high as 100%.
2 rice blast
Rice blast is generally mild in southern China and Jiangnan late rice areas, with an area of ​​2.05 million mu, a year-on-year decrease of 12.7%. The field of rice leafhoppers is common, the diseased leaf rate is generally 0.5% to 5%, and the high rice area in northeastern Guangxi, central Guangxi and western Guangxi is 11% to 21%. The ear-necked scorpion is mainly found in the double-season late rice in the south of the Yangtze River. The diseased ear rate is generally 0.1% to 1.1%, and the peak field in Jiangxi lead mountain is up to 9%.
3 Southern rice black streaked dwarf disease
The southern rice black-streaked dwarf disease occurred lightly in the southern rice areas of southern China and the south of the Yangtze River, and the local occurrence was heavier. The current area was 240,000 mu, a year-on-year decrease of 62.9%. The disease rate in the field is generally 0.1% to 2.7%, and the local high in Guinan, Guidong and Guizhong is 4% to 23%. The rate of local disease in western Guangdong is relatively high. For example, Qingcheng District is the newly-occurring area this year, and the rate of diseased plants in local fields is as high as 40% to 50%.
4 other diseases
Orange leaf disease occurs in the southern rice area of ​​southern China, the disease rate is generally 0.02% to 15%, the high is 20% to 40%; the diseased leaf rate is generally 0.01% to 0.5%, and the high is 2% to 10%. %. The occurrence of bacterial diseases in rice in southern China and Jiangnan rice areas has increased from the same period of the previous year, and the overall incidence is mild. The southern part of Guinan and western Guangdong are heavier.
According to the National Meteorological Center, the rainfall in the eastern part of the Yangtze River in the next 10 days is more than normal, which is conducive to the relocation of rice planthoppers and rice leaf rollers and the further occurrence of pests and diseases. Especially in areas with high bases of rice planthoppers in northern Fujian, it is necessary to be alert to the outbreak of rice planthoppers. It is recommended that all localities attach great importance to it, and do a good job of checking and repairing the local conditions according to local conditions, so as to achieve "the autumn grain is not enough for one day, and the prevention and control will not relax for one day", and strive for a bumper harvest of autumn food.
