油菜菌核病菌(Sclerotinia sclerotiorum)%啶酰菌胺%抗性风险
油菜菌覈病菌(Sclerotinia sclerotiorum)%啶酰菌胺%抗性風險

Sclerotinia sclerotiorum%boscalid%resistance risk
为了解油菜菌核病菌（Sclerotinia sclerotiorum)对杀菌剂啶酰菌胺的抗性风险，在室内采用菌株Hnm1和 A53-3对含不同浓度多菌灵和啶酰菌胺的 PDA 培养基进行连续30代的抗性筛选。结果表明，啶酰菌胺在相同浓度下，对菌株 Hnm1的抑制率由初始的35.83%下降至30.48%，对菌株 A53-3的抑制率由初始的61.07%下降至54.40%。通过抑制率的下降可推断油菜菌核病菌对啶酰菌胺的抗性风险与对多菌灵的抗性风险相近。

In order to evaluate resistance risk of Sclerotinia sclerotiorum to boscalid, resistance to boscalid, carbendazim was selected consecutively for 30 generations by fungicide-amended PDA medium in laboratory. Results showed that inhibition per-cent of boscalid at the same concentration to isolate Hnm1 was dropped from initial 35.83% to 30.48%. Inhibition percent to isolate A53-3 was dropped from initial 61.07% to 54.40%. Based on the decrease of inhibition percent, resistance risk of S. sclerotiorum to boscalid was similar to that to carbendazim.
