Abstract

This study investigated the efficacy of different concentrations of date vinegar in inhibiting the growth of the phytopathogenic fungus Fusarium oxysporum. The results demonstrated that date vinegar suppressed fungal growth, with the 20% concentration achieving complete inhibition (100%) compared with the control treatment, which exhibited no inhibition (0%). The findings also revealed that the germination percentage of cucumber seeds after 10 days increased with increasing concentrations of date vinegar compared with the treatment inoculated with the pathogen alone. The highest germination percentage (95.14%) was recorded in the 15% and 20% date vinegar treatments. Furthermore, the seedling mortality rate was reduced to 0% in all treatments containing date vinegar, whereas the treatment inoculated solely with the pathogenic fungus exhibited a seedling mortality rate of 100% after 14 days. The greenhouse experiment further demonstrated the beneficial effects of date vinegar application on the vegetative growth characteristics of cucumber plants cultivated in plastic pots. Significant improvements were observed in plant height, fresh and dry biomass, and leaf area compared with the pathogen-inoculated treatment. In addition, date vinegar treatments reduced disease severity caused by the pathogenic fungus, resulting in improved plant growth and vigor. These findings indicate that date vinegar has considerable potential as an ecofriendly and sustainable alternative for the management of fungal diseases in cucumber plants. The results of the present study represent a promising step toward sustainable agricultural development and environmental protection by reducing dependence on synthetic chemical pesticides that may adversely affect ecosystems and human health.
