摘　　要：为了明确不同杀菌剂拌种对小麦散黑穗病的防效,使用5种杀菌剂进行小麦种子拌种处理,评价不同处理对小麦散黑穗病防治效果与小麦产量的影响。结果表明:不同药剂处理对小麦散黑穗病均有一定抑制作用,其中11.2%甲基硫菌灵悬浮种衣剂18 g/100 kg处理的防效达96.84%;从产量方面分析比较,11.2%甲基硫菌灵悬浮种衣剂15 g/100 kg处理的小区小麦增产效果明显,可显著减少散黑穗病引起的产量损失。11.2%甲基硫菌灵悬浮种衣剂是一种有前途的小麦散黑穗病抑制剂。In order to determine the control effect of seed dressing with different fungicides on wheat loose smut,five kinds of fungicides were used to wheat seed, and the control effect of wheat head smut and wheat yield were evaluated. The results showed that different treatments had certain inhi-bitory effect on wheat loose smut,and the control effect of 11. 2 % Thiophanate methyl with 18 g/100 kg seed suspension coating was 96. 8 4 % . Analysis and comparison showed that the yield loss caused by wheat loose smut could significantly reduce by 15 g/y100 kg seed suspension treatment of 11. 2 % Thiophanate methyl. 11. 2% methyl thiophanate suspension seed coating agent is a promising inhibitor of wheat loose smut.
