Summary The control of rhizomania, one of the most important diseases of sugar beet caused by the B eet necrotic yellow vein virus , remains limited to varietal resistance. In this study, we investigated the putative action of B acillus amylolequifaciens lipopeptides in achieving rhizomania biocontrol through the control of the virus vector P olymyxa betae . Some lipopeptides that are produced by bacteria, especially by plant growth‐promoting rhizobacteria, have been found to induce systemic resistance in plants. We tested the impact of the elicitation of systemic resistance in sugar beet through lipopeptides on infection by P . betae . L ipopeptides were shown to effectively induce systemic resistance in both the roots and leaves of sugar beet, resulting in a significant reduction in P . betae infection. This article provides the first evidence that induced systemic resistance can reduce infection of sugar beet by P . betae .
