几种微生物杀线虫剂对烟草根结线虫病的防效试验

Study of microorganic nematicide for controlling tobacco knot nematodiasis

为了确定 3种微生物杀线虫剂IPC、ZK7、4 12对烟草根结线虫病的防治效果 ,通过田间小区试验 ,从烤烟的生物学性状、发病情况、经济学性状等方面进行了全面考察。结果表明 ,3种微生物杀线虫剂的防效均优于生物农药 ,其防治效果分别为 6 1 7%、6 4 7%、70 5% ,对烤烟生物学性状、经济学性状的改善效果也明显。因此 。

Using field plot test,the control effects of three microorganic nematicides:IPC,ZK7 and 412 were tested from tobacco biological character,infection situation and economic properties.The results suggested that the control effects were 61.7%,64.7% and 70.5%,which were better than biological reagent.These microorganic nematocides could be applied for tobacco production.
