Table 1. Effect of crude extracts of different Trichoderma species on growth inhibition of R. solani.
| Isolates | Radial growth of R. solani (cm) | % mycelial inhibition | ||
|---|---|---|---|---|
| 24 h | 48 h | 72 h | ||
| T. asperellum | 0.0 ± 0.0* | 0.0 ± 0.0 | 0.1 ± 0.0 | 97.7a** |
| T. harzianum | 0.9 ± 0.1 | 1.1 +0.1 | 1.2 ± 0.1 | 72.7b |
| Trichoderma sp. | 1.3 ± 0.2 | 2.5 +0.2 | 3.4 ± 0.0 | 22.7c |

The results are the mean value (± SE) of two independent experiments, each with four replicates.
**
Values followed by the different letters are statistically different by Duncan's multiple range test (p < 0.05).
