Suppression of grey mould in tomato leaves by menadione pretreatment. (A) Reduced symptom development on the Botrytis cinerea-inoculated tomato leaves pretreated with different concentrations of menadione. Photos were taken 4 days post-inoculation (dpi). (B) Decreased lesion diameters on the grey mould infected tomato leaves and relative protection efficacies mediated by menadione pretreatment. Means followed by the same letter are not significantly different at 5% level by least significant difference test.
