玉米矮花叶病药剂防治试验

Experiment on the Controlling of Maize Dwarf Mosaic by Pesticides

田间试验结果表明，８３ 增抗剂、病毒Ａ、菌毒清、植病灵Ⅱ、ＰＶ－ ８６ － １ 等抗病毒制剂喷施、种衣剂拌种，对玉米矮花叶病都有一定的防治效果。其中以８３ 增抗剂１００ 倍、病毒Ａ 和菌毒清５００倍、病毒清＋ 叶面宝３００ 倍、呋多种衣剂１∶６０ 拌种效果较好。

Field experiments were conducted to determine the controlling effect of some pesticides to maize dwarf mosaic. Results showed that coating seed with seed coating formulation and spraying maize plant with 83 Zengkangji, Bingdu A, Junduqing, Zhibingling Ⅱ, and PV-86-1 et al have certain controlling effect to maize dwarf mosaic. Among the pesticides, good controlling effect could be obtained when 83 Zengkangji, Bingdu A and Junduqing, and Bingduqing plus Yemianbao was sprayed in the rate of 1:100, 1:300, and 1:500, respectively, and Fuduo seed coating formulation was applied in the rate of 1:60. The experimental results can be applied in maize production.
