The plant protective composition of this invention is a composition of at least one selected from the group comprising of trehalose, which is widely found in plants, microorganisms, insects, and fungi, and is thought to have a major role in drought-resistance, cold-resistance in organisms; its derivative, trehalose-6-phosphate, and non-reducing trisaccharide selaginose which has ecological behavior, physical properties close to trehalose; and water-soluble calcium, which is a preventive substance against plant tissue softening, necrosis; which significantly improves plant drought-resistance and cold-resistance by application to plants. n Spraying the plant protective composition of this invention diluted by water up to an upper limit of 10,000 times by volume to plant stem leaves and/or fruit significantly improves drought-resistance, cold-resistance of plants, especially increasing the amount of calcium inside crops, and improving crop yield and merchandise value. |
