Phytophthora infestans is the causal agent of potato late blight. This pathogen is usually controlled by fungicides, but new European regulations have imposed changes in crop protection management that have led to a search for alternative control measures. The induction of plant defense responses by elicitors is a promising new strategy compatible with sustainable agriculture. This study investigated the effect of eliciting a defense response in potato against P. infestans using a formulation of the COS-OGA elicitor that combines cationic chitosan oligomers (COS) and anionic pectin oligomers (OGA). Trials were conducted under greenhouse conditions to assess the ability of COS-OGA to control P. infestans. The results showed that three foliar applications with this elicitor significantly increased potato protection against late blight in controlled conditions. The activation of potato defense genes was also evaluated by RT-qPCR during these trials. Two pathogenesis-related proteins, basic PR-1 and acidic PR-2, were rapidly and significantly up-regulated by the elicitor treatment. Our results therefore suggest that the COS-OGA elicitor increases potato protection against P. infestans and that this protection could be explained by an increase in the expression of potato defense genes rather than by biocide activity.
