The deployment of crop production equipment is a pertinent part of the surging productivity in Europe and American agriculture. Agricultural chemical utilization is often required at particular periods and locations for optimal site management of crop infested with pests. Basically, piloted agricultural planes are typically deployed to handle large, continuous land areas, crops, unobstructed and are not competent enough when being used over small plots. An Unmanned Aerial Vehicle (UAC) is remotely controlled based on preprogrammed flight plans and can be deployed to do timely and efficient utilization over small area designs. This paper describes the implementation of spray-system and its incorporation with flight control system having a complete autonomous, unmanned landing and vertical take-off helicopter. Sprayer actuation can be triggered by the preset positional coordinates as monitored by the equipped Global Positioning System (GPS). The developed spray system has the potential to provide accurate, site-specific crop management when coupled with UAV systems. It also has enormous potential for vector control in areas not easily accessible by personnel or equipment.
