Abstract : The antifungal activity of phyto-fabricated silver nanoparticle (AgNP) alone and in combination with the fungicide, mancozeb, against F. oxysporum f. sp. lycopersici were investigated in-vitro and under field trial. Treatments were applied at different concentrations (5.0, 7.5, 10.0, 12.5 %) while media without the treatments served as control. AgNP alone demonstrated an insignificant mycelial radial growth inhibitory effect (p > 0.05) on the fungus compared to the control. The mean radii of mycelial growth inhibition for AgNP alone ranged from 24.67 ± 0.33 to 25.33 ± 1.20 mm while the control was 25.67 ± 0.33 mm. However, AgNP/Mancozeb (50 % v/v) demonstrated significant inhibitory activity (p < 0.05) on the fungus compared to the control with a marked percentage inhibition ranging from 51.00 to 74.98 %. The fungal flora and physico-chemical parameters of the experimental plot were analyzed before sowing and soil-drench method was used to introduce the treatments in the field study at different concentrations (25, 50 and 75 mg/mL) while plants inoculated with the pathogen alone served as control. After 7, 14 and 21 Days Post Inoculation (DPI), disease incidence for plants treated with AgNP alone and AgNP/Mancozeb was highest at 50 mg/mL (44.60 ± 5.40 % and 39.93 ± 6.64 % respectively) at 21 DPI compared to control (29.30 ± 4.00 %). This study has demonstrated the optimization of ineffective large-sized AgNP by pairing with mancozeb and maximizing their synergistic effect against F. oxysporum f. sp. lycopercisi.
