Fungicidal compositions for agricultural and horticultural use which contain as an active ingredient one or more compounds selected from the group consisting of tartaric acid, oxalic acid, fumaric acid, citric acid, alkali metal salts of these organic acids, ferric citrate, ferric lactate, glycerine, aluminum chloride and esters formed between sugar and higher fatty acids having 8 to 18 carbon atoms. These compositions exhibit excellent protective effects against attack by plant disease fungi, bacteria or virus and have no phytotoxicity and no mammalian toxicity and present no risk of causing the pollution of soil, human, cattle and poultry. The protective effects of these active ingredients are greatly enhanced when they are applied to plants in combination with a phosphatide. And a method for protecting plants by the use thereof.
