PROBLEM TO BE SOLVED: To provide an agricultural spraying agent for being sprayed on leaves or the like as an aqueous solution which is rapidly dried. SOLUTION: The agricultural spraying agent in which calcium lignin sulfonate and a water-soluble calcium compound different from the calcium lignin sulfonate are blended in the ratio of 2:8 to 5:5 is not conspicuous even when being deposited on fruit skins or leave and does not disturb the photosynthesis because of the light transmission. When being applied on a fruit surface, the spraying agent functions as a fruit surface protective agent. When being applied on the leaves, the spraying agent exhibits high effect as a calcium fertilizer because of the absorption from the leaves. Because the drying speed is high and the leaves and fruit surface are rapidly dried after spraying the aqueous solution, germs such as fungi suspended in the air is prevented from depositing and propagating.
