Damoatech (CEO: Jung Hu-min) has signed a non-exclusive license agreement with the Korea Agriculture Technology Promotion Agency (KOAT) for a patent filed by the Rural Development Administration (RDA) — Application No. 10-2025-0122344, titled "Mobile Pesticide Spraying System for Greenhouses and Its Operation Method."

The agreement covers the full territory of the Republic of Korea and runs from April 20, 2026 through April 19, 2029.

■ Solving a Long-Standing Problem in Greenhouse Pest Control

Conventional greenhouse spraying has long relied on manual labor — a process that is physically demanding, exposes workers to chemicals, and struggles to reach both the upper and lower surfaces of crops evenly.

Automated systems have been introduced, but a persistent challenge remains: clogged nozzles caused by residual pesticide left inside spray lines after each operation.

This patented technology addresses both issues with two core mechanisms:

• Mobile nozzle structure: A motorized spray unit travels along the greenhouse interior, delivering uniform coverage to both upper and lower crop canopies
• Post-spray auto-flush function: After spraying is complete, clean water is automatically injected through the nozzle and piping to flush out residual pesticide — preventing clogging and reducing maintenance burden

■ From Ginseng Greenhouses to Full Smart Farm Integration

The technology was originally developed with ginseng cultivation facilities in mind — a crop particularly sensitive to disease and requiring precise, consistent spray coverage. Damoatech's commercialization roadmap expands outward from this initial application:

■ Strengthening Damoatech's Smart Agriculture Stack

Damoatech is a fabless semiconductor company specializing in precision agriculture IoT solutions — including soil sensors, atmospheric sensors, irrigation controllers, and spray controllers. This technology transfer expands the company's integrated offering across the full smart farming workflow:

Sense → Analyze → Act

With the addition of an automated, self-cleaning spray system, Damoatech is positioned to deliver end-to-end crop management solutions for greenhouse operators seeking to reduce labor costs, improve spray consistency, and minimize equipment downtime.

This product incorporates patented technology (Application No. 10-2025-0122344) developed by the Rural Development Administration of Korea, licensed to and manufactured by Damoatech.
