Abstract: Free N-lower alkanoyl sulphanilic acid hydrazides are prepared by reacting the corresponding N-lower-alkanoyl-anilide with chlorosulphonic acid reacting the N-lower alkanoyl sulphanilyl chloride thus obtained with hydrazine.  In an example N-formyl sulphanilic acid hydrazide is prepared by reacting formanalide and chlorosulphonic acid to form N-formyl sulphanilyl chloride which is then reacted with hydrazine.  Salts, e.g. sodium, potassium, ammonium, and lithium salts or hydrochloride sulphate, phosphate, nitrate, citrate, acetate, lactate, oxalate, succinate of free N-loweralkanoyl sulphanilic acid hydrazide may be prepared by reacting with the corresponding alkali, or acid.  Heavy metal salts e.g. manganous, cobaltous, cupric, ferric, mercuric, lead, nickelous, chromic, cadmium and aluminium of N-lower alkanoyl sulphanilic acid hydrazides are prepared by reacting a solution of a heavy metal salt e.g. manganous sulphate monohydrate with the sodium salt of the hydrazide e.g. the N-formyl-, N-acetyl-, N-propionyl-, N-isobutyryl-, and N-butyrylsulphanilic acid hydrazides.  Alkaline earth metal salts of N-alkanoylsulphanilic acid hydrazide are obtained by adding a solution of an alkaline earth metal salt to a solution of the sodium salt of the hydrazide.ALSO:A growth promoting and plant protecting composition comprises an N-lower-alkanoyl-sulphanilic acid hydrazide or alkali metal, alkaline earth metal, heavy metals or acid addition salts thereof, a carrier and may also include a surfactant.  The active ingredient may be dispersed in a carrier selected from a water-miscible solvent containing a surfactant, a dusting powder, a water dispersible powder.  Other fungicidal, virucidal, insecticidal, bactericidal, or acaricidal materials and other adjuvants such as stickers, may also be included.  Specified active ingredients are N-acetyl, N-formyl-, N-propionyl, N-isobutyryl and N-butyryl sulphanilic acid hydrazides and the sodium, potassium, ammonium, and lithium salts and hydrochlorides sulphate, phosphate, nitrate, citrate, acetate, lactate, oxalate, succinate, manganeus, zinc, cobaltous, cupric, ferric, mercuric, lead, nickelous, chromic, cadmium, aluminium, barium, calcium, strontium and magnesium salts.ALSO:A growth promoting and plant protecting composition comprises an N-lower-alkanoylsulphanilic acid hydrazide or alkali metal, alkaline earth metal, heavy metal or acid addition salts thereof, a carrier may also include a surfactant.
