Figure 1.

Antagonistic activities of B‐36 broth filtrates against Fusarium oxysporum at different concentrations. Sterilized water was used as a negative control (a), and F. oxysporum was cultured on PDA with various concentrations of B‐36 broth filtrate (b) at 25°C for 7 days. The colony diameters and inhibition rates of F. oxysporum were recorded (c) (□ colony diameter; ■ inhibition rate). Values are means ± SE, n = 3. Different letters above the bars denote significant differences at P < 0·01 according to Duncan’s multi‐range test. [Colour figure can be viewed at https://www.wileyonlinelibrary.com]
