In vitro inhibitory effect by different concentration of IONPs against Ralstonia solanancerum. (A) Diameter of bacterial growth inhibition (mm) caused by IONPs: (a) negative control, (b) positive control, (c) 4.5 mg/ml, (d) 7.7 mg/ml (e) 15 mg/ml and (f) 30 mg/ml; (B) bacterial growth inhibition zone caused by IONPs. The data points are represented as mean ± SD (n = 6). Statistical difference denotes at *P ≤ 0.0001 compared to positive control.
