Systemic acquired resistance (SAR) is one of the most promising ways to support plants in fight against viruses, bacteria and fungi. This phenomenon is activated by pathogen attack or artificially, by using resistance inducer (elicitor) which imitates the plant‐pathogen interaction. Both, biological or chemical factors interact with plants and stimulate their immune system against infections before first symptoms of diseases occurs. SAR inducing properties of elicitors could be potentially utilized to develop a new plant protection strategies. This paper presents synthesis, phytotoxicity and SAR induction efficacy of four newly obtained amide derivatives of 2,6‐dichloroisonicotinic acid and four known amide derivatives of isonicotinic acid. Induction of plant resistance tests were performed on tobacco Nicotiana tabacum var. Xanthi infected by Tobacco mosaic virus (TMV). Six of the eight presented substances indicate resistance inducing properties, which were expressed by decrease of necrotic area on leaves caused by viral infection by 44 to 92 % in comparison to the control plants. Moreover, obtained results show that presented compounds exhibited better plant resistance inducing properties than salicylic acid, oxalic acid and β‐aminobutyric acid used as reference.

异烟酸衍生物作为新型高效系统获得性抗药性（SAR）诱导剂
系统获得性抗性（SAR）是支持植物抵抗病毒，细菌和真菌的最有前途的方法之一。这种现象是通过病原体攻击或通过使用模拟植物与病原体相互作用的抗性诱导剂（激发子）而人为激活的。在疾病的第一症状出现之前，生物或化学因素都与植物相互作用并刺激其免疫系统抵抗感染。SAR诱导子的特性可以潜在地用于开发新的植物保护策略。本文介绍了四种新获得的2,6-二氯异烟酸酸酰胺衍生物和四种已知的异烟酸酰胺衍生物的合成，植物毒性和SAR诱导功效。在烟草Nicotiana tabacum上进行了植物抗性试验的诱导变种 Xanthi被烟草花叶病毒（TMV）感染。所提供的八种物质中的六种具有抗药性，与对照植物相比，其表现为病毒感染引起的叶片坏死面积减少了44％至92％。此外，获得的结果表明，与作为参考的水杨酸，草酸和β-氨基丁酸相比，所提出的化合物具有更好的植物抗性诱导性能。
