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 × 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 14days. 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 eco-friendly alternative to preserve the quality of the agricultural products and to increase their shelf life.
