Abstract Fungi are the primary infectious agents in plant crops and many post-harvest fungal diseases of fruit and vegetables causing significant economic losses worldwide. Here, the antifungal effect of Prosopis glandulosa extract (PgE) against phytopathogenic fungi was evaluated. The effect with PgE (5, 4, 2, 1, 0%) as AI (%) and radial growth rate reduction (Kr %) were determined in vitro in Colletotrichum gloeosporoides, Fusarium oxysporum, Rhizopus oryzae and R. stolonifer (1 9 105 spores/mL). The phytopathogenicity of fungal strains was performed under in vivo conditions (room temperature, 25–30 °C and refrigeration, * 4 °C) by fruit surface inoculation method on strawberries, tomatoes and carrots by recording the development of mycelial growth, necrosis, soft rot and dehydration symptoms showed on each fruit at 14 days. The extract (5%) showed the highest AI against C. gloesporioides (* 96%), and F. oxysporum (* 79%) and growth rate reduction of 74.92% and 64.82% respectively. Likewise, the extract controls the development of phytopathogenicity symptoms against C. gloesporioides and F. oxysporum in vivo conditions, nevertheless, was less

efficiency against both Rhizopus species. The P. glandulosa extract represents an efficient, economical, and ecofriendly alternative to preserve the quality of the agricultural products and to increase their shelf life. Keywords Antifungal Mesquite Phytopathogen Prosopis glandulosa Fungal infection of plant pathogenic species results not only loss in the crop yield, but also billions of US dollars are lost annually around the world [1]. A significant loss (35–50%) of horticultural products after harvest has been reported in strawberry, tomato and carrot, primarily due to infection due to Botrytis, Colletotrichum, Fusarium and Rhizopus and other phytopathogenic fungi [2]. A wide range of products are being studied to protect crops, mainly plant extracts [3]. The honey mesquite P. glandulosa Torrey var. glandulosa, Fabaceae family is a native of the southwest of USA and northern Mexico. The extract from Fabaceae family as an
