农药混配防治烟草病毒病田间试验

为了较有效地防治烟草病毒病,于2003年进行了喷施农药混配剂(1 5%"植病灵"800倍 氨基酸液肥300倍,"病毒灵"1000倍 "保得"生物肥1000倍)及抗病毒药剂("毒消"800倍,1 5%"植病灵"800倍)田间防效试验。结果表明:1 5%"植病灵"800倍 氨基酸液肥300倍在玉溪市红塔区和华宁县试验点发病盛期防效分别为72 50%和64 18%,防治效果相对较好;其次是"毒消"800倍在红塔区和华宁县试验点防效分别为64 61%和57 21%。

Field Experiments on Mixed Pesticides for Tobacco Virus Diseases Controlling

In order to control tobacco virus diseases more effectively, the experiments on spraying mixed chemicals (1.5% Traconlyl alcohol at a dilution of 800 amino acids fertilizer at a dilution of 300 and Moroxydine at a dilution of 1000 Baode microbial fertilizer at a dilution of 1000) and virucides (Duxiao at a dilution of 800 and (1.5%) Moroxydine at a dilution of 800) were carried out in tobacco fields in 2003. The results indicated that during full occurrence stage of the diseases, the control effects of Traconlyl alcohol at a dilution of 800 amino acids fertilizer at a dilution of 300 were 72.50% and 64.18% and Duxiao at a dilution of 800 were 64.61% and 57.21% at Hongta district in Yuxi and experimental point in Huaning County, respectively. The control effects were relatively good.
