A potential cause of the dissemination of the potato ring rot bacterium Clavibacter sepedonicus (Cs) is the use of automated seed potato cutters. The present study focuses on the question of whether disinfection practices are sufficient to prevent the transmission of Cs from contaminated machine parts to a new tuber lot. The disinfection efficacy was determined by establishing the culturability of Cs that remained after spray application of sodium-p-toluenesulfochloramide solution on clean and fouled specimens of machinery material that had been provided with an imprint of Cs biofilm. Although conventional spraying, with the authorized concentration of sodium-p-toluenesulfochloramide, of inoculated rubber, PVC and lacquered steel led to a substantial decrease of colony forming units, the treatment was insufficient for complete eradication of Cs. The presence of dirt negatively affected the efficacy of the disinfectant.

马铃薯环腐菌Clavibacter sepedonicus传播的一个潜在原因(Cs) 是使用自动种薯切割机。本研究的重点是消毒措施是否足以防止 Cs 从受污染的机器部件传播到新的块茎批次。消毒效果是通过建立对甲苯磺酰氯胺钠溶液喷洒在带有 Cs 生物膜印记的干净和污染的机械材料样本上后剩余的 Cs 的可培养性来确定的。虽然常规喷洒，以规定浓度的对甲苯磺酰氯胺钠，接种橡胶、PVC 和漆钢导致菌落形成单位显着减少，但该处理不足以完全根除 Cs。污垢的存在会对消毒剂的功效产生负面影响。
