摘　　要：试验结果表明 ,12 .5 %全蚀净悬浮剂 2 0ml 6 6 7m2 、4 0ml 6 6 7m2 拌种处理对小麦全蚀病有良好的防效 ,对小麦白穗率的防效分别为 86 .3%、93.2 % ,小麦增产效果分别为 2 0 .3%、2 5 .1% ,均明显优于 2 5 %粉锈宁可湿性粉剂拌种效果。此外 ,12 .5 %全蚀净悬浮剂拌种处理对小麦根系生长有刺激作用 ,毛细根数量增加 ,根系加长 ,鲜重增加。对小麦安全无药害。The results of test indicated that Latitude 12.5% could control Gaeumammomyces graminis var.tritici at a certain degree. Mixing wheat seeds with the dosage of 20ml/667m^2 and 40ml/667m^2, the controlling effect of white head were 86.3%、93.2%. And there were yield increase of 20.3% and 25.1% than that of Bayletan 15% seed-coating. In addition, field application showed that coating wheat seeds with Latitude could stimulus the growth and development of wheat root ,and the number of root increased, the length of root became longer ,weigh increased,etc. It was safe to coat wheat seeds with Latitude.
