The effect of various pesticides on the biofilm formation by the phytopathogenic bacterium Clavibacter michiganensis ssp. sepedonicus (Cms), the potato ring rot causative agent, was explored for the first time. Systemic herbicides: 2,4-D, diuron, glyphosate, clopyralid, fluorodifen, as well as the commercial preparations "Lazurite," "Ridomil Gold," and the mitochondria inhibiting pesticides analog, sodium monoiodoacetate, were studied. These pesticides' effect on the Cms biofilm formation was shown to be distinct and dependent on the agent under question. Cms biofilm formation was reduced when exposed to sodium monoiodoacetate, as well as "Lazurite" preparation, that could be due to the bactericidal effect of these agents. 2,4-D and "Ridomil Gold" preparation stimulated the biofilm formation. Systemic herbicides diuron, glyphosate, clopyralid, fluorodifen did not exert appreciable influence on the process of bacterial biofilm formation.
首次探究了多种农药对马铃薯环腐病菌——密执安棒形杆菌环腐亚种（Cms）生物膜形成的影响。研究了内吸性除草剂：2,4-滴、敌草隆、草甘膦、氯吡嘧磺隆、氟乐灵，以及商业制剂“蓝铜矿”“金雷多米尔”，还有线粒体抑制性农药类似物碘乙酸钠。结果表明，这些农药对Cms生物膜形成的影响各不相同，且取决于所研究的药剂。当暴露于碘乙酸钠以及“蓝铜矿”制剂时，Cms生物膜形成减少，这可能是由于这些药剂的杀菌作用。2,4-滴和“金雷多米尔”制剂刺激了生物膜的形成。内吸性除草剂敌草隆、草甘膦、氯吡嘧磺隆、氟乐灵对细菌生物膜形成过程没有显著影响。
