A germ affected with blue-eye mold, regardless of the size of the mold is a damaged kernel. If the mold is distinct, it is not necessary to open or scrape the kernel. When necessary, carefully lift the germ cover to avoid destroying evidence of mold.
NOTE: Do not confuse blue-eye mold with purple plumules. Any amount of mold that penetrates the seed coat of the kernel is considered damage (e.g., crown, tip, sides, or back).
