近日从全国农技中心了解到,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,稻飞虱及其传播的病毒病发生程度轻于上年。预计下阶段“两迁”害虫、稻瘟病、稻纹枯病等病虫害重发风险仍然较大。各地需高度重视,加强监测预警,实施分类指导,采取有效措施,减轻病虫危害。1.“两迁”害虫总体中等,局部偏重发生。 Recently learned from the National Agricultural Technology Center that the current southern China and southern Yangtze rice are at the tillering stage, the southern quarter of a quarter of rice and northeast single-season rice in the milk filling period, the middle and lower reaches of the Yangtze River single-crop late rice in booting to flowering heading. Pest and disease in the field were generally moderately to moderately severe, with rice leaf roller, rice stem borer, rice blast and sheath blight occurring heavier than those in the previous year. The incidence of planthoppers and their transmitted virus diseases was lighter than that of the previous year. It is estimated that the risk of recurrence of pests and diseases such as pests, rice blast and rice sheath blight will still be greater in the next stage. All localities should attach great importance to strengthening monitoring and early warning, implementing classified guidance and taking effective measures to reduce pests and diseases. 1. “two move ” pests are generally medium, partial emphasis occurs.
