  1. Data are mean ± standard error of replicates, and the number of spore production was determined 7 days after treatment, the mycelia dry weight was determined 5 days after inoculation. Different letters in the same column mean significant difference at the P < 0.05 level by Duncan’s new multiple range test (n = 12)
