The invention provides a herbicide synergistic safe composition as well as a preparation method and application thereof, and relates to the technical field of herbicides. The synergistic safe composition of the herbicide comprises the following components in percentage by mass: 1-5% of p-isopropyl toluene sulfonamide, 1-5% of a synergist, 10-20% of an emulsifier, 1-5% of a dispersant, 0.5-2% of a suspending aid and the balance of methyl esterified soybean oil. According to the herbicide synergistic safe composition prepared by the invention, the damage of the herbicide to corn can be relieved through the action of isopropyl toluene sulfonamide; through the effect of the synergist, the control effect of the herbicide on weeds is improved, and meanwhile, the phytotoxicity relieving effect on isopropyl toluene sulfonamide is improved. The synergistic safe composition is applied after being mixed with a herbicide, so that the dual effects of improving the weed control effect of the herbicide and reducing the phyt
