Abstract :
[en] Wheat is one of the most cultivated crops in the European Union. This cereal must however face important losses every year due to a major foliar disease known as Septoria Tritici Blotch (STB) caused by the fungus Zymoseptoria tritici. Disease control mainly depends on phytosanitary products. However, conventional agriculture is evolving towards more sustainable practices, out of respect for human health and the environment. Elicitors are considered as promising biological control tools and draw major interest in Integrated Pest Management strategies. These plant-immunity triggering compounds induce a general systemic resistance of the plant to a large spectrum of diseases. This study focuses on the screening of nine potential elicitors to protect winter wheat against Zymoseptoria tritici. Greenhouse trials were carried out to measure the ability of the different products to reduce disease foliar symptoms (necrosis, chlorosis and pycnidia). In addition, the biocide activity of these products towards the pathogen was evaluated under greenhouse and laboratory conditions. Furthermore, the modes of action of the best elicitors were investigated by studying the activity of some key defense enzymes of wheat. The corresponding results will be presented and discussed with the perspective to choose the two best elicitors for field trials and undertake further investigations on the signaling pathways triggered in the plant.
