PROBLEM TO BE SOLVED: To provide a liquid spray system accurately controlling spraying amount of liquid such as agrochemical, fertilizer, and carrying out easy and effective maintenance after spraying. SOLUTION: This invention comprises to the agrochemical spray system 1 comprising a water level sensor 12 inserted into a tank 3, a flow meter 15 measuring the flow of the agrochemical 8 pumped out from a pump 4, a counting terminal 13 linked to the flow meter 15 and the water level sensor 12, a mobile terminal 14 linked with the counting terminal through wireless communication and a valve 16 controlled so as to be closed through the mobile terminal 14, in addition to the tank 3 for storing the agrochemical 8, the pump 4, a hose 6 and a spray 5. The agrochemical is sprayed out from the sprayer 5 by opening the valve 16 by an operator 10. The counting terminal 13 which constitutes the controlling means, regulates the valve 16 to be closed through the mobile terminal 14 by detecting the flow measured by the flow meter 15 reaching a predetermined amount and enables an accurate spray of the agrochemical.
