In vitro plate assay. PDA was amended with epiBL (0, 0.2, 2,
10, 20, 50, 100, or 200 µM). Plates were inoculated with a 5-mmdiameter
plug of F. culmorum, which was harvested from a 7-dayold
PDA plate. Plates were incubated at 25°C in darkness. After
72 h, the colony diameter (in centimeters) was measured. The
experiment was carried out twice, each containing three technical
replicates per treatment.
