由于秸秆还田的普及以及去年秋季小麦播种时土壤湿度普遍偏大,今春小麦纹枯病在我省有偏重发生趋势。在石家庄周围业已发现科农199和石麦14等品种感病较重,有的地块病株率高达90%以上。每年小麦起身前后是田间喷雾防治小麦纹枯病的最佳时机,希望农民朋友近期到地里查看自己麦田发病情况,及时采取防治措施。 Due to the popularity of straw returning and the generally high soil moisture during sowing of wheat in autumn last fall, spring wheat sharp blight in spring tends to be more prevalent in our province. Around Shijiazhuang, it has been found that susceptible strains such as Korong 199 and Shimai 14 are heavier, and the rate of diseased plants in some plots is as high as over 90%. Every year before and after the wheat gets up, it is the best time for field spray to control wheat sheath blight. We hope that farmers and friends will check the incidence of their wheat fields in the field and take timely prevention and control measures.
