Citrus fruits are among the commercial fruits most consumed and most affected by fungal rot during storage. Chemical management
of fungal diseases poses numerous health and environmental concerns. Biological control using plant extracts has been
considered a safe, eco-friendly, and sustainable management practice. The present study aimed to investigate the effects of Alhagi
maurorum extract and pesticide (carbendazim) on fungal pathogens. Fungal pathogens were isolated from infected fruits and
identified based on morphological characteristics. These isolates were tested for their pathogenicity in citrus fruits. The antifungal
activity of these preparations was performed using diffusion assay. Morphological characters identified these isolates as
Penicillium digitatum, Penicillium italicum, and Alternaria sp. These isolates produced characteristic infections in citrus fruits.
All the preparations, A. maurorum extract, carbendazim, and a combination of these two exhibited antifungal activity against
P. digitatum, Penicillium italicum, and Alternaria sp. However, the combination of A. maurorum essence and carbendazim produced
pronounced effects (50 % more) against fungal pathogens. The results showed that the combined effect of Alhagi maurorum
essence and extract with carbendazim effectively controls fungal pathogens infection of orange and tangerine during storage.
