Abstract
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.
