Inhibitory activity of 1, 2, 3, and 4 on Rhizoctonia solani mycelium growth after 48 h of incubation.
| Compound | Concentration (µmol/L) | ||
|---|---|---|---|
| 75 | 150 | 300 | |
| Length of Colony [mm] (Inhibition [%]) | |||
| 1 | 9.8 ± 0.6 (31) | 8.1 ± 0.7 (42) | 6.8 ± 1.2 (52) |
| 2 | 14.5 ± 0.6 (−3) | 11.3 ± 0.2 (20) | 10.6 ± 0.5 (25) |
| 3 | 12.8 ± 0.2 (10) | 13.1 ± 0.9 (7) | 12.9 ± 0.2 (9) |
| 4 | 14.4 ± 0.2 (−2) | 14.0 ± 0.2 (1) | 14.0 ± 0.8 (1) |
Values are presented as the mean ± SD (n = 4). Inhibition [%] = (1-colony length of sample/colony length of control) × 100. Colony length of the control was 14.1 ± 1.0 mm.
