近些年,在中国水稻上发生了一种严重病害——条纹叶枯病。条纹叶枯病是由灰飞虱传播的病毒病,该病具有间歇性暴发的特性,主要是看灰飞虱群体的带毒率,经过一定时期积累,灰飞虱一旦形成较强的带毒群体,就会引发几年的病害流行期。近年又处在该病的流行期,如不防治可能造成30%~50%的损失,甚至绝收毁种,现在又到了防治该病的关键时期。 In recent years, a serious disease, rice stripe disease, has occurred on rice in China. Striped leaf blight is a virus disease transmitted by the planthopper, the disease has intermittent outbreak characteristics, mainly to see the size of the population of Laodelphax striatellus, after a certain period of accumulation, Laodelphax striatellus once formed a strong poison Groups, it will lead to several years of disease epidemic period. In recent years, it is in the epidemic period of the disease, if not prevention and control may cause 30% to 50% loss or even destroy the species, it is now a crucial period to prevent and treat the disease.
