The solid component of a 0.01-10% aqueous emulsion applicable as an anti-wilting and anti-withering agent for plants or fruit consists of 100 parts by weight of the product of reaction of 1 mol. of normal aliphatic alcohol containing 16-22 carbon atoms inclusive in its molecule or a mixture of the said alcohols with not more than five mols. of ethylene oxide, and 5-50 parts by weight of an emulsifier chosen from alkali metal, ammonium and triethanol ammonium salts of fatty acids having 12-16 carbon atoms inclusive and alkali metal salts of sulphuric acid esters of higher aliphatic alcohols having 12-16 carbon atoms inclusive. The compositions may be applied to a plant or fruit by dipping or spraying, and inhibit wilting and withering by suppressing transpiration. In examples the alcoholic components used include monooxyethylene cetyl alcohol, monooxyethylene stearyl alcohol, monooxyethylene docosanol, monoxyethylene eicosanol and a mixture of equal parts of monooxyethylene stearyl alcohol and monoxyethylene docosanol. The emulsifiers used in the examples include sodium oleate, sodium dodecyl sulphate, and triethanol ammonium oleate.ALSO:The solid component of a 0,01-10% aqueous emulsion applicable as an antiwilting and anti-withering agent for plants or fruit consists of 100 parts by weight of the product of reaction of 1 mol. of normal aliphatic alcohol containing 16-22 carbon atoms inclusive in its molecule or a mixture of the said alcohols with not more than five mols. of ethylene oxide, and 5-50 parts by weight of an emulsifier chosen from alkali metal, ammonium and triethanol ammonium salts of fatty acids having 12-16 carbon atoms inclusive and alkali metal salts of sulphuric acid esters of higher aliphatic alcohols having 12-16 carbon atoms inclusive.
