Efficacy of the antagonistic yeasts in suppressing of rice sheath blight disease caused by R. solani DOAC 1406 in rice plants grown in pots in the greenhouse.
| Treatment | Plant Height (cm) a | Lesion Height (cm) b | Disease Incidence (%) | Disease Suppression (%) |
|---|---|---|---|---|
| Control (negative control) | 94.0 ± 2.9a | 0d | 0d | 0 |
| R. solani (positive control) | 92.0 ± 2.6a | 23.8 ± 1.6a | 25.9 ± 2.3a | 0 |
| R. solani + T. indica DMKU-RP31 | 93.0 ± 4.1a | 7.2 ± 1.4b | 7.7 ± 1.4b | 70.3 |
| R. solani + T. indica DMKU-RP35 | 93.2 ± 2.3a | 8.3 ± 1.5b | 8.8 ± 1.4b | 66.0 |
| R. solani + W. anomalus DMKU-RP25 | 92.6 ± 3.0a | 8.1 ± 1.0b | 8.7 ± 0.8b | 66.4 |
| R. solani + 3% Validamycin | 93.4 ± 3.5a | 3.9 ± 0.5c | 4.2 ± 0.6c | 83.8 |
Each value represents a mean “±” standard deviation (SD). In the same column, data followed by the different lower-case letters are significantly different according to Duncan’s multiple range test at p≤0.05. a Plant height was an average height from five rice plants (measured above ground to the tallest leaf). b Lesion height was an average lesion height from five rice plants; in each plant the height of all lesions was measured and averaged.
