小麦全蚀病又称黑脚病,主要危害小麦、玉米等禾本科作物,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,甚至扩展蔓延速度快,一般地块从零星发病到成片死亡,只需3年时间。近几年来,小麦全蚀病在安阳县零星发生,对小麦安全生产构成严重威胁,笔者长期深入田间地头,实际调查了豫北地区全蚀病发病因素及其传播途径,并总结了针对性的防治对策。 Total eclipse of wheat, also known as blackfoot disease, the main harm to wheat, corn and other grass crops, wheat disease, tillering reduced into a low spike rate, grain weight decreased, the morbidity onset, the greater the rate of decrease, 20%, heavy reduction of more than 50%, or even spread the expansion of speed, the general block from sporadic disease to death, just 3 years. In recent years, wheat eclogodes occur sporadically in Anyang County, which poses a serious threat to the safety of wheat. The author went deep into the field for a long time and actually investigated the etiological factor and its transmission path of ecliposis in the North of Henan Province and summarized the targeted Prevention and control measures.
