Brazilian citrus industry ripe for autonomous sprayer shift

Orchard operator cites worker safety, high efficiency, reduced chemical use benefits.

Jacto Arbus 4000

Orange grove management has long been a labour-intensive activity in Brazil. One of the most necessary and dangerous aspects of the process is pest control.

Orchard spraying is a frequent and necessary task that can take considerable time given the scope and scale of many Brazilian citrus orchards. The inability to cover large areas accurately and in a timely fashion makes the management of these insects challenging. At the same time, there is a high risk of contamination to workers, who must be covered head-to-toe in protective gear during spraying activities.

For Brazilian-based Jacto, one of the largest manufacturers of agricultural sprayers in the world, it’s an environment ripe for automation—and autonomy. Jacto manufactures a wide range of spraying, fertilizer spreading, planting, harvesting and pruning equipment, always with an eye on driving efficiency through technology.

“… with NovAtel solutions and our strong working relationship, we believe the role of autonomous precision agriculture solutions is solid.”
