The present invention relates to a highly concentrated transparent “bordeaux liquid” having multi-functionality, and to a preparation of a highly concentrated transparent “bordeaux liquid” having multi-functionality. More specifically, the present invention is directed to a “bordeaux liquid” applicable to various disease and insect damages on the basis of the features thereof, in which: the bordeaux liquid can be stably preserved for a long period of time without causing poor dispersion both at the concentration at the time of concentration and the concentration at the time of use before the spraying of the bordeaux liquid after the bordeaux liquid is sprayed on leaves or fruit trees, water-insoluble calcium hydroxide and water-insoluble calcium sulfate are attached to the leaves of the fruit trees to inhibit a vigorous respiration action or block sunlight, and as a result, the photosynthetic rate of plants is not decreased yellow-white precipitates, even when adhering to fruits or chili peppers, do not damage the beauty of the products and the bordeaux liquid does not permit easy exfoliation or elution by external physical pressure or rainwater even after spray and after drying. The purpose of the present invention is to provide: a highly-concentrated multi-functional “bordeaux liquid”, in which a multi-functional “bordeaux liquid” having the foregoing functionalities is highly concentrated to be convenient in use and a method for preparing a highly-concentrated multi-functional “bordeaux liquid”. The present invention relates to a method for preparing highly concentrated high-functional lime bordeaux liquid, wherein, when the lime bordeaux liquid is used, there is no problem of a nozzle or the like becoming clogged due to the precipitation of lime as a raw material ingredient there is no need for agitation at each time of use since the precipitation of raw ingredients does not occur during the long-term storage of the bordeaux liquid the bordeaux liquid has excell
