Abstract
A method of controlling moss by applying to grass infested with moss a dry composition including: a) a source of nitrogen such as isobutylenediurea or methylene urea; b) a non-ionic surfactant or wetting agent; c) a metal containing salt, and d) an acidic pH adjusting agent effective to adjust the pH of the composition to a pH of between 2.5 and 5 when wetted on grass. The dry composition may be a granular composition, and may be applied by broadcasting over a large area.
Claims11
A method of controlling moss, comprising applying to grass infested with moss a dry composition comprising:
- a. coated granules of a source of nitrogen, wherein said source of nitrogen comprises a member selected from the group consisting of urea, diureas, methylene ureas, ureaforms, urea condensations, nitrates, ammonia, and isobutylenediurea;
- and wherein said granules are coated with a clay, a wax, or a polymer coating;
- b. coated granules of a non-ionic surfactant or wetting agent, wherein said granules are coated with a clay, a wax, or a polymer coating,
- c. coated granules of a metal containing salt, wherein said metal containing salt comprises a member selected from the group consisting of iron-, copper-, zinc-, or magnesium-containing phosphates, halides, or sulfates, and wherein said granules are coated with a clay, a wax, or a polymer coating, and
- d. coated granules of an acidic pH adjusting agent effective to adjust the pH of the composition to a pH of between 2.5 and 5 when wetted on grass by normal amounts of rain or watering, wherein said granules are coated with a clay, a wax, or a polymer coating.
