PROBLEM TO BE SOLVED: To provide a plant resistance inducer having a novel chemical structure for growing plants strong against disease stress.SOLUTION: A resistance inducer comprises a compound represented by formula (1) as an active ingredient. In the formula R1 is a C1-6 alkyl group, an aryl group, a substituted aryl group or an arylmethyl group X is formula (1a) or formula (1b) R2 is an aryl group or a substituted aryl group and n is an integer of 1-4 (excluding a compound in which R1 is a methyl group, X is formula (1a) or formula (1b), R2 is a phenyl group or a methylenedioxyphenyl group, and n is 1).COPYRIGHT: (C)2016,JPO&INPIT【課題】病害ストレスに強い植物を育成するため新規な化学構造の植物用抵抗性誘導剤の提供。【解決手段】式(1)で表される化合物を有効成分とする抵抗性誘導剤。[R1はC1-6アルキル基、アリール基、置換アリール基又はアリールメチル基;Xは式(1a)又は式(1b);R2はアリール基又は置換アリール基;nは1~4の整数;(但し、R1がメチル基、Xが式(1a)又は式(1b)、R2がフェニル基又はメチレンジオキシフェニル基、nが1を表す化合物は除く)]【選択図】なし
