小麦全蚀病又称黑脚病,主要危害小麦、玉米等禾本科作物,是一种毁灭性较大的病害,被列为河南省补充植物检疫对象。小麦感病后,分蘖减少,成穗率低,千粒重下降,发病愈早,减产幅度愈大,轻者减产10～20%,重者减产50%以上,扩展蔓延速度快,一般地块从零星发病到成片死亡,只需3年时间。了解小麦全蚀病的发病症状、规律、传播途径是我们发现和采取有效防治的前提条件。
Total eclipse of wheat, also known as black-foot disease, is a major devastating disease caused by gramineous crops, such as wheat and corn. It is listed as a supplementary plant quarantine object in Henan Province. After the wheat is infected, the number of tillers decreases, the percentage of ear to ear is low, the weight of thousand kernels is decreased, the earlier the disease is, the larger the rate of yield reduction is, the lower rate of yield is 10-20%, and the rate of yield reduction is more than 50% The incidence of death to pieces, just 3 years. It is a prerequisite for us to find out and take effective prevention and control of the etiology, regularity and transmission of wheat eclipse.
