| 摘 要： | 为合理防治烟草黑胫病和野火病，减少抗药性产生，减少农药残留，本文就云南省烟草黑胫病菌对甲霜灵的抗药性，烟草野火病菌对农用链霉素的抗药性形成和发展的影响因素进行了研究。结果表明施药次数的增加与药剂施用浓度的增高，可明显提高烟草黑胫病对甲霜灵抗药性水平。喷药次数的多少与喷药间隔时期可明显影响烟草野火病菌对农用链霉素的抗药性。

| Abstract: | To control tobacco wild fire disease rationally and reduce resistance and pesticide pollution, the influence factors of fungicide resistance formation and development on main tobacco diseases were studied. The results indicated that the increasing of spraying frequency and consistency could improve the fungicide resistance level of tobacco black shank disease (Phytophthora parasitica var. nicotianae) against metalaxyl obviously. The spraying quantity and the period between the two spraying could influence obviously the fungicide resistance of tobacco wild fire disease (Pseudomonas syringae pv. tabaci) against agricultural streptomycin. |
