According to the present invention, control of a drone for performing cultivated land photography and pesticide spraying can be performed remotely to achieve efficient cultivation management of the user, and various data regarding the state of the cultivated land and the crop can be calculated by analyzing the photographed image The present invention also provides an unmanned pesticide supply system for monitoring information useful for a user through a configuration. To this end, the present invention provides a management terminal comprising: a management terminal for detecting at least one of cultivated land lot information and injection information input from a user, transmitting the information to a drone, and displaying data received from the server； Receiving GPS information from the satellite, tracking the location of the cultivated land corresponding to the cultivated land lot information detected by the management terminal, photographing the cultivated land at the tracked position simultaneously with the flight, A drone for spraying pesticide on the cultivated land； And an image of the cultivated land photographed by the drone is analyzed with a pre-stored image processing program to guide the diagnosis and prescription of the cultivated land, and the yield of the crop of the cultivated land is calculated on the basis of the analyzed image, And estimating the price information of the crop by comparing and analyzing the obtained yield and the statistical information according to the region previously stored, and transmitting at least one of the guided diagnosis, the prescription, the calculated yield, and the prepared price information to the management terminal Server.본 발명은 경작지 촬영과 농약 분사를 수행하는 드론의 제어가 원격으로 이루어지도록 구성하여 사용자의 효율적인 경작 관리를 달성할 수 있고, 촬영된 영상을 분석하여 경작지의 상태 및 작물에 관한 다양한 데이터를 산출하는 구성을 통해 사용자에게 유용한 정보가 모니터링되도록 하는 무인 농약 공급 시스템을 제공하는 것을 목적으로 한다. 이를 위해 본 발명은 사용자로부터 입력되는 경작지 지번정보, 분사정보 중 적어도 하나를 검출하여 드론으로 전송하고, 서버로부터 수신되는 데이터를 디스플레이하는 관리 단말기； 인공위성으로부터 GP
