Table 4 Effect of different concentrations of ZnO NPs on percentage inhibition of mycelial growth (MG) of phytopathogenic fungus A. niger

From: Green approach for the synthesis of ZnO nanoparticles using Cymbopogon citratus aqueous leaf extract: characterization and evaluation of their biological activities

Treatments (μg/mL)	% Inhibition MG^a
ZnO NPs
25	10.15 ± 3.0^g
50	18.75 ± 2.1^f
100	22.50 ± 1.0^f
150	60.00 ± 0.6^e
200	62.50 ± 0.9^e
250	69.37 ± 0.5^d
500	75.12 ± 0.7^c
1000	87.62 ± 0.3^b
2000	95.13 ± 0.1^a
Control^b	00.00 ± 0.0^h

^aEach value is the average of three replicates. Mean ± SD followed by the different superscript letters (a-g) in a column of each concentration is a significant difference at p < 0.05 and the % inhibition of MG was measured compared to the growth of the control (0%). ^bControl without NPs
