小麦纹枯病是一种由土壤丝核菌引起的土传病害。九十年代以来,随着小麦连作和产量水平的提高,该病在鲁南地区发生愈来愈重,一般减产8～15％,重病田减产20％以上,成为小麦生产的重要病害。为此,我们于1990～1992年进行了以三唑醇、三唑酮拌种为主防治小麦纹枯病试验研究,并在全区大面积推广应用,取得显著成效。 Wheat sheath blight is a soil borne disease caused by soil Rhizoctonia. Since the 1990s, with the continuous improvement of wheat production and the level of output, the disease has been getting heavier and heavier in the Lunnan area, with a general decrease of 8-15% and a reduction of more than 20% in severe diseases, making it an important disease in wheat production. To this end, we carried out in 1990 ~ 1992 with triadimenol triadimefon seed-based control of wheat sheath blight experimental study, and in large area popularization and application, and achieved remarkable results.
