An effective, environmentally compatible herbicidal composition utilizes under saponified ammonium soaps of fatty acids having from 6 to 11 carbon atoms. Potassium and sodium soap compositions, at 90 to 100% saponification, are effective to kill mosses, lichen, liverworts and algae, without damage to higher plants. The compositions are herbicidally effective and do not stain substrates, such as patios, walks, stairs, walls and the like, to which it is applied.

[ What is claimed is:] [1.] A herbicidal composition, consisting essentially of:a herbicidally effective amount of an active ingredient selected from the group consisting of under saponified ammonium soaps of sorbic acid, caprylic acid, pelargonic acid, capric acid, undecylenic acid and mixtures thereof, wherein the active ingredient has a soap to free fatty acid ratio in the range of about 3:4 to 2:1,the composition being herbicidally effective on a range of algae, liverworts, mosses and higher plants and exhibiting no residual staining of substrates to which it is applied.
