Dodine (n-dodecylguanidine acetate) and glyodin (2-heptadecyl-2-imidazoline) at rates as low as 500 µg/ml have demonstrated highly significant activity as foliar protectants against infection by tobacco mosaic virus (TMV). Dodine appeared slightly more effective than glyodin. Both compounds were superior to dry milk.
