一般认为斑枯病(Siptoria)造成的为害在10～20%范围内,但是最近几年的研究表明其为害程度较大。据材料报导,颖枯病(Septoria noducum)引起的产量损失可以达到56～76%。发现最近在欧州一些国家斑枯病有严重发展的趋势。主要的原因是由于种植禾谷类作物的面积扩大;大量种植了高感的矮杆品种;农业技术向深耕方向变化,结果造成有利于残茬上菌源的保存和积累。防治斑枯病最根本的方法是种植抗病的品种,但是,目前已知的禾谷类作物品种都在某种程度上受斑枯病感染。采用农业防治措施对控制病害的发展可起一定的作用,一是提高了
Siptoria is generally considered to cause damage in the range of 10-20%, but studies in recent years have shown that it is more harmful. According to the material, the yield loss caused by Septoria noducum can reach 56-76%. It has been found that there has been a serious development of spot blight in some European countries recently. The main reason is due to the expansion of the area planted with cereal crops; the cultivation of high-intensity dwarf varieties in large numbers; and the change of agricultural techniques in the direction of deep plowing, resulting in the preservation and accumulation of bacterial sources on the stubble. The most fundamental way to prevent and control spot blight is to cultivate disease-resistant varieties. However, the currently known varieties of cereal crops are all affected to some extent by spot blight. The use of agricultural control measures to control the development of disease can play a role, one is to improve
