The main disease of date palm in Morocco is a vascular fusariosis (Bayoud) caused by Fusarium oxysporum f. sp. albedinis (Foa). Although many strategies for controlling this Fusarium wilt have been introduced [1–4], considerable losses still occur. A promising approach for minimizing the severity of diseases is based on the induction of systemic resistance using localized pre-treatment with elicitors in order to enhance resistance to pathogen infection [5]. Jasmonic acid (JA) is a natural phyto- hormone involved in many processes during plant development
