Photograph showing the inhibition of fungal growth by biocides. (a) The disks on each PDA plate were loaded with the same concentration of different biocides. Clearing zones indicate where the growth of Fusarium spp. NK-NH1 and NH2 was inhibited. (b) The inhibition efficiency of different biocides. The ordinate is the diameter of antibiotic inhibition zone. Vertical lines indicate standard deviations of three replicate tests for each.
