As Africa’s population continues to grow, the need for sustainable agricultural practices has intensified, sparking greater interest in nanofertilizers This review critically evaluates agronomic efficiency and environmental sustainability of African context. It combines existing research on nanofertilizers’ effectiveness, nutrient-use efficiency, impact. Nanofertilizers have shown a boost up 30% compared conventional fertilizers. also highlights benefits such as enhanced crop yields (up 25% increase maize production), reduced chemical fertilizer requirements 40% reduction nitrogen application), improved soil health. The analysis informs policy, research, practice aimed at optimizing nanofertilizer deployment agriculture. projected global 2.4 billion by 2050 that solutions never been more important. Our conveys an assessment potential contribution food security.

The overuse of synthetic pesticides has triggered resistance in insect pests and caused severe environmental impacts, emphasizing the urgent need for sustainable alternatives Integrated Pest Management (IPM). This study aimed to biosynthesize characterize chitosan-coated silver nanoparticles (AgChNPs) using Galega officinalis leaf extract evaluate their insecticidal effects against Drosophila suzukii (Diptera: Drosophilidae), a key pest fruit crops worldwide. biosynthesized AgChNPs (257.2 nm) were polydisperse, crystalline, stable, as confirmed by UV-vis spectroscopy, dynamic light scattering (DLS), X-ray diffraction (XRD), transmission electron microscopy (TEM). exhibited strong toxicity across multiple developmental stages. Combined larvicidal pupicidal activity reached 48.3% 73.3% at 500 1000 ppm, respectively, significantly affecting immature As consequence, adult emergence declined 46.7%, 51.7%, 26.7% 250, 500, ppm. Among emerged adults, 71.7% displayed sublethal effects, with 62.8% showing morphological malformations (deformed wings, dehydration) 37.2% presenting cuticle demelanization. Adulticidal bioassays revealed progressive mortality over 48 h, 96% Overall, acute chronic toxicity, reduced emergence, induced alterations, demonstrating potential nanotechnological tool effective control within IPM programs.
