AMB Express

Table 3 The effect of gamma irradiation at different tested doses on the anti-Ralstonia solanacearum activity by the biofabricated SiO₂/Ag nanocomposite

Gamma irradiation dose (Gy)	ZoI (mm) 1st trial	ZoI (mm) 2nd trial	ZoI (mm) 3rd trial
0	28.6 ± 0.57^b	30.4 ± 0.50^b	28.5 ± 1.00^b
200	33.6 ± 0.57^a	34.6 ± 0.40^a	34.1 ± 1.25^a
400	24.0 ± 1.0^c	ND	ND
600	19.6 ± 0.57^d	ND	ND
800	14.0 ± 1.0^e	ND	ND

ND not detected
Data for ZoI are shown as the mean ± SD of triplicate measurements from independent experiments
a–e means with different superscripts in the same column are considered statistically different (P ≤ 0.05)
