I believe there was considerable research about 30 years ago on the
effects of herbicides on bryophytes. My recollection is that much was
done by Dominick Basile, and that mostly mosses were resistant to
herbicides. In Pacific Northwest America, all one needs for a moss
garden is spray a shady area with herbicide.

For additional anecdotal data, I knew a grower of Christmas trees in
Washington State who used Atrazine to control grasses around his
trees. There was a circle of pure moss around each tree.
