yThe frequency (%) of fungi (x) were log transformed (log10[x + 1]) prior to analysis to stabilize the variance. L, A. flavus L morphotype; SBG, SBG strains; P, A. parasiticus; T = A. tamarii (not found in 2010). zThe means of paired treated and control fields for a crop within each column with different lowercase letters are significantly different (Student’s t-test, α = 0.05). Means of fungi within a row with different uppercase letters are significantly different (Fisher’s LSD test, α = 0.05).
