At one time, at least a dozen proprietary fertilizers and other products containing mowrah meal were marketed for earthworm control on golf courses (9). The use of the method declined in the late 1940s and 1950s with development of chlordane and other earthworm-toxic synthetic pesticides., Mowrah meal is rich in saponins,natural soaps or surfactants found in the leaves and seeds of oats, spinach, alfalfa, chickpeas, soybeans, ginseng, tea, and hundreds of other plants (8). Reference to commercial products or trade names is made with the understanding that no discrimination is intended and no endorsement by the University of NebraskaLincoln is implied.
