Title: Improvements in sulphur preparations for use as insecticides, fungicides and ovicides
IPC: A01N59/02
Filed: 1933-02-24
Abstract: A colloidal sulphur preparation, to be diluted with water for use as a horticultural spray or as an animal dip, is prepared by dissolving sulphur in a solvent and homogeneously admixing the solution with an emulsifying base comprising an oleaginous material which has been saponified by means of an anhydrous saponifying agent.  In some cases a "greased buffer" containing a protein, a fatty acid or glyceride, a tanning agent and water, with or without the addition of starch or dextrin, trisodium phosphate, potassium hydroxide, ammonia or other alkali, may also be added; or a "tanned buffer" of similar composition, but without fatty acid or glyceride, may be used.  The compositions may be mixed with other active substances such as copper colloids and compounds, chromates, arsenic compounds, fluorides, silico fluorides phenols, pyridine, paradichlorobenzene, naphthalene, nicotine, pyrethrum, Paris green, Bordeaux mixture, and petroleum. According to examples the solvent for the sulphur may be carbon bisulphide, sulphur chloride, naphthalene, toluol or trichlorethylene; and the emulsifying base may be prepared from mixtures of coconut fatty acids, oleic acid and stearic acid saponified by anhydrous alcoholic sodium or potassium hydroxide or by triethanolamine, water being added, if desired, after saponification. Examples of "greased buffers" are (1) a mixture of glue, casein, starch, trisodium phosphate, oleic acid, water and formaldehyde; (2) a mixture of glue, blood albumen or haemoglobin, potassium hydroxide or ammonia, oleic acid, water, and formaldehyde, chrome alum, tannic acid or bichromate; (3) a mixture of glue, starch or dextrin, formalin or other tanning agent, oleic acid or red oil, and water; and (4) a mixture of glue, casein or blood albumen, starch or dextrin, alkali metal hydroxide, formaldehyde, palmitic or like acid or a glyceride, and water.ALSO:A colloidal sulphur preparation, to be diluted with water for use as a horticultural spray or as an animal dip, is prepared by dissolving sulphur in a solvent and homogeneously admixing the solution with an emulsifying base comprising an oleaginous material which has been saponified by means of an anhydrous saponifying agent.
