烯唑醇超微粉体种衣剂防治大麦主要病害的研究

采用5%烯唑醇超微粉体种衣剂处理大麦种子,研究该种衣剂对大麦主要病害的防治效果及对大麦生长发育的影响。试验结果表明,药种比1:400~500处理大麦种子,可提高大麦出苗率,调控幼苗生长,植株干重、鲜重显著增加;对大麦条纹病(Helminthosporium gramineum)、根腐病(Helminthosporium sativum)、散黑穗病(Ustilago nuda)的防病效果分别为90.4%~88.7%、90.1%~91.8%、100%~83%,增产16%~12%。

Study on Diniconazole Ultramicro Powdered Seed Coating Chemical Control Main Diseases of Barley

Barley seeds were coated by 5% Diniconazole ultramicro powder. This experiment is to research about its control effect to main diseases and effect to seedling growth of barley. The results showed that the seeds were treated by 1:400~500 of this chemical and seeds can improve emergence rate, seedling growth and dry and fresh weight of the plants. Its control effect to Helminthosporium.gramineum, Helminthosporium.sativum,and Ustilago.nuda of barley is 90.4%~88.7%?90.1%~91.8% and 100%~83% respectively. The yield was increased 16%~12%.
