据植保部门发布的信息,当前,华南、江南晚稻正处于分蘖期,江南一季中稻和东北单季稻处于灌浆乳熟期,长江中下游单季晚稻处于孕穗至抽穗扬花期。田间病虫害总体中等至偏重发生,其中稻纵卷叶螟、二化螟、稻瘟病、纹枯病发生程度重于上年。结合当前病虫害发生基数分析,预计8月下旬至9月中、下旬,稻飞虱在华南、江南、长江中下游稻区仍将偏重发生,局部大发生;稻纵卷叶螟在江南稻区偏重发生,华南、长江中下游稻区总体中等,局部偏重发生;二化螟在江南、长江中下游和江淮稻区中等发生,局部偏重发生;稻瘟病在江南、西南、长江中
According to the information released by the plant protection department, at present, southern China and southern Yangtze rice are at the tillering stage. One season of middle season rice in the southern part of the Yangtze River and the northeast part of the Yangtze River are in the stage of milky grouting. The latter part of the middle and lower reaches of the Yangtze River lies in the booting stage. The overall incidence of pests in the field was moderate to moderate, with the occurrence of rice leaf roller, rice stem borer, rice blast and sheath blight heavier than in the previous year. Combined with the current base incidence analysis of pests and diseases, it is estimated that in late August to late September, planthoppers in southern China, southern Yangtze River, the middle and lower reaches of the Yangtze River will continue to be partial, large; rice leaf roller in southern Jiangsu area emphasis Occurred in South China and the middle and lower reaches of the Yangtze River. The rice fields were moderately and partially localized. Chilo suppressalis occurred moderately in the southern part of the Yangtze River and in the middle and lower reaches of the Yangtze River and in the middle and lower reaches of the Yangtze River. The rice blast occurred in the south, southwest,
