Fig 4. The cell-free supernatant of QBA5 greatly inhibited disease severity not only in detached leaves but also fruits.

A: Disease severity of gray mold on tomato leaves. 1 and 4: leaves treated with cell-free supernatant of QBA5. 2: Leaves treated with YEPD as the negative control. 3: Leaves treated with Methylthio diethofencarb (667mg/L) as the positive control. B: Disease severity of gray mold on tomato fruits. a: Tomato fruit treated with YEPD as the negative control. b: Tomato fruit treated with the cell-free supernatant of QBA5. c: Tomato fruit treated with Methylthio diethofencarb (667mg/L) as the positive control. Columns with different letters are significantly different. (p<0.05).
