The purpose of this study was to assess how much the resistance inducing agent BION® can reduce infection with the Fusarium equiseti, the causal agent of the date palm leaf spot disease. Additionally, the study assessed the effect of applying various Bion concentrations in inducing resistance and reducing infection with the F. equiseti. The results obtained showed that spraying Bion on date palm leaves provided protection for the leaves, and the infection level with F. equiseti varied among the cultivars tested. Bion application as a spray at the concentration of 1.5 mg/ml, sprayed on date palm leaves three days before inoculation with the fungus, reduced the extent of invasion that reached 1.9 cm compared to 2.91 cm for the control treatment. The expansion of disease infection following treatment with Bion concentration of 0.5 mg/ml, three days before inoculation with the F. equiseti, reached 2.55 cm.
