All the 97 endophytic fungal isolates obtained in this study were tested for production of antifungal volatile organic compounds (VOCs) using the double-dishes method described by Huang et al. (2011). A mycelial agar plug of an endophyte was placed on PDA in a Petri dish and incubated at 20 _C for seven days. Another fresh PDA dish containing an agar plug with mycelia of S.sclerotiorum was placed inversely over a bottom dish containing the seven-day-old culture of an endophyte to establish a doubledish set, which was immediately sealed with a piece of parafilm. In the control treatment, a bottom PDA dish inoculated with S. sclerotiorum was placed inversely over a bottom dish containing PDA without endophyte to make a double-dish set, which was also sealed with a piece of parafilm. There were three double-dish sets serving as three replicates for each endophyte and or the control. Diameter of the S. sclerotiorum colony in each double-dish set was measured after incubation at 20 _C for 72 h and the percentage of growth inhibition was calculated using the method described by Huang et al. (2011). The experiment was repeated once.
