Abstract

A plant growth stimulant comprises a mixture of a plurality of water soluble mineral double salts, commercial alginate and colchicine. Preferably 0,0002 to 0,0005 per cent of colchicine and 0,5 to 1,5 per cent of commercial alginate are employed. The composition may also contain soft soap, rubber or latex, fillers such as kieselguhr, sterilized leather or leather powder from which glue, gelatine and fats have been removed, ground paper, humus, stable manure, green or vegetable matter, hop manure or guano impregnated with gum, wax, sap or resin emulsions, and waxes such as beeswax' carnauba wax, Japanese waxes, paraffin wax, ceresine and crude ozokerite. Natural growth substances such as yeast and maize oil and synthetic hormones such as indole acetic acid and naphthyl acetic acid may be included together with radio-active salts if desired. Insecticides such as derris may be included. The compositions may be applied as a coating to seeds, tubers or roots for example grain or potatoes or they may be applied to the soil as an aqueous mulch or spray, or in the form of solid pellets. According to the preferred embodiment the composition consists of commercial alginate, rubber latex, potassium phosphate, ammonium nitrate, and a mixture of sodium, manganese, zinc, copper, ferric, potassium, lithium, and magnesium ammonium phosphates, together with colchicine, soft soap, borax, potassium iodide, a soluble cobalt salt, and a soluble double salt of silicon and ammonia or a salt of nickel selenium, fluorine or sulphur. The composition is preferably made up in a natural mineral water containing in solution sodium, magnesium, potassium, sulphur, iodine, iron, boron, lithium, copper, zinc and manganese, for example Aachen and Vichy waters.
