It can be configured to be installed in compartments.

The concentration sensor 1500 consists of a pH sensor and measures the acidity (pH) of the diluted pesticide.

According to the above configuration, when water is replenished in the pesticide tank 300, the tank valve 1400 is operated by the concentration sensor 1500 and the control unit 1600 to remove the diluted water in the pesticide tank 300. The pesticide stock solution stored in the stock solution tank 1300 can be automatically supplied to the pesticide tank 300 until the pesticide reaches the concentration value set in the control unit 1600.

In addition, the diluted pesticide in the pesticide tank 300 has a slightly higher concentration of the pesticide sprayed in the early to middle part of the pesticide spraying process as the pesticide component with a high specific gravity precipitates, and the pesticide sprayed in the mid to late part has a somewhat lower concentration. According to the configuration, if the concentration of the pesticide decreases in the middle or latter part of the pesticide spraying, the pesticide stock solution is automatically supplied and the concentration is maintained constant, so that the pesticide can be sprayed at a constant concentration throughout the pesticide spraying operation.
