小麦根病是指由土壤真菌导致的根腐和茎基腐病害。山东省小麦根病以全蚀病、纹枯病为主,其次为镰刀菌根腐、蠕虫菌根腐。近年因连作面积扩大和水肥条件的改善,小麦根病害呈明显上升趋势,特别是小麦纹枯病发生危害愈来愈重,感病株的小麦干粒重降低1～3克,严重制约着小麦生产水平的提高。1987年烟台市农科所就开始着手从事该项研究,现已筛选出防治小麦根病的有效药剂——三唑醇。 1991～1992年文登市试验结果表明:三唑醇0.3％拌种及三唑醇十增产菌混合拌种对纹枯病的防效显著高于粉锈宁。干粒重分别比对照增加2.03克和
Wheat root disease is root rot and stem-base rot disease caused by soil fungi. Wheat root disease in Shandong Province to eclipse, sheath blight-based, followed by Fusarium root rot, worm root rot. In recent years, due to the expansion of continuous cropping and the improvement of water and fertilizer conditions, wheat root disease showed a clear upward trend, especially the incidence of wheat sheath blight more and more serious, susceptible strains of wheat reduced by 1 to 3 grams of dry weight, seriously restricting the wheat Improve the level of production. Yantai Agricultural Science Institute in 1987 began to engage in the study has been screened out effective prevention and treatment of wheat root disease agent - triadimenol. From 1991 to 1992, the test results of Wendeng City showed that the control effect of mixed dressing with 0.3% triadimenol and triadimenol ten on the sheath blight was significantly higher than that of triadimencin. Dry weight increased 2.03 g and control respectively
