Abstract The environment faces serious threats from climate change, food security challenges, and a growing population. UN Global Goals emphasize the urgent need for sustainable agriculture to secure production. We must adopt innovative solutions bolster agroecological resilience increase output with minimal environmental impact. Here, we investigate antimycotic properties of silver nanoparticles (PP-AgNPs) at various concentrations in controlling Fusarium wilt tomato crop improvement under laboratory, greenhouse, field conditions. Various instruments were utilized characterize green-synthesized PP-AgNPs. results indicated broad UV peak 428 nm spherical morphology sizes ranging 1 3.5 nm, as confirmed by SEM TEM. Analyses indicate that antifungal potency PP-AgNPs (150 µg/mL) against oxysporum was found be 80.9% (Colony diameter: D A ) 95.4% (Measured area -M ), respectively, contrast control treatment. Notably, concentration 100 µg/mL signified best effect greenhouse trials, reducing disease severity 34.5% (greenhouse) 21.8% (Field: average both years). also render other benefits, including improved plant growth parameters, fruit weight, number, bioactive compounds.
