| 2.00 | 8.19 ± 4.80E+07a | 5.83 ± 0.977E+08a | |
| FV | 0.10 | 1.63 ± 0.375E+07b | 6.69 ± 1.59E+08a |

Values represent the average with standard error of 9 replicates (pooled form 3 independent experiments, each with 3 replicates). Letters indicate significant differences between treatments (Kruskal-Wallis test and Wilcoxon rank-sum test for multiple comparisons, p ≤ 0.05, n = 9). PE: Plant extract, FV: Formulated version, NG: No bacterial growth.
