Effect of different concentrations of yeast strains m11, me99 and ca80 on biocontrol efficacy of Botrytis cinerea in ‘Thompson Seedless’ grape berries. Fruits were wounded, treated by dipping for 30 s in a cell suspension of yeast strain, treated after 24 h with a spore suspension of pathogen (1 × 104 spores mL−1) and stored at 20 °C for 7 days.
| Concentration of Yeast (Cells mL−1) | Rot Incidence (%) | ||
|---|---|---|---|
| m11 | me99 | ca80 | |
| Control | 78.81 ± 4.76 c | 84.52 ± 6.63 b | 94.05 ± 1.19 c |
| 1 × 107 | 34.52 ± 7.81 b | 64.29 ± 5.46 b | 60.71 ± 7.14 b |
| 1 × 108 | 20.24 ± 4.76 ab | 35.71 ± 2.06 a | 33.33 ± 5.19 a |
| 1 × 109 | 11.90 ± 6.30 a | 26.19 ± 7.81 a | 32.14 ± 2.06 a |
Data expressed as mean ± standard error. Control means the treatment of pathogen only. Different letters in the same column indicate differences among concentrations according to the Tukey test (p ≤ 0.05).
