Intelligent Sprayer

Functionality & Mechanism

This precision agricultural spraying system, developed by the USDA Agricultural Research Service (ARS) in collaboration with The Ohio State University, automates pesticide application. The system utilizes high-speed laser sensors to scan the surrounding plant canopy and foliage density. An integrated algorithm then analyzes this data in real-time to precisely control a series of nozzles, directing spray only where needed. This mechanism adjusts the spray volume and targets application, moving beyond the continuous, fixed-rate output of conventional sprayers.

Development & Context

The news coverage highlights several key aspects of the sprayer's development:

• The system was created to modernize pesticide application beyond outdated, fixed-rate methods that have been in use for over 60 years.
• Testing indicated the sprayer reduced airborne spray drift by up to 87 percent and lowered spray loss on the ground by up to 93 percent.
• Nursery growers using the technology reported chemical savings of around $230 per acre annually, with a potential one-year return on investment.
• The project has received a national award from the American Society of Agricultural and Biological Engineers and interest from equipment manufacturers.

Intended Use & Scope

This system is designed for specialty crop growers, such as those managing orchards and nurseries, seeking to optimize pesticide application. Its primary function is to support cost-effective and targeted pest management while minimizing chemical waste and environmental runoff.
