Intensive horticultural production is a sector seeking to provide high-quality foods by means of safe and sustainable procedures in compliance with regulations. This requires improvements in the spraying technologies since currently plant protection products are applied by means of hand-held equipment due to its lower cost and easy maintenance. In order to fulfil these requirements, a remote-controlled vehicle prototype (ROBOT SPRAY) was used. After optimizing the spray profile and the air assistance system of the “ROBOT SPRAY” sprayer in laboratory, its performance using two different nozzle sets (full cone and hollow cone) with and without air assistance was compared with those of a spray gun in a greenhouse tomato crop. The spray deposition on canopy, spray coverage and losses to soil were assessed. The “ROBOT SPRAY” provided better penetration and coverage on the underside of the leaves while no improvement was shown with the use of air assistance. Overall, a higher spray deposition was observed for the full cone nozzles when compared to hollow cone nozzles.

Abstract

Intensive horticultural production is a sector seeking to provide high-quality foods by means of safe and sustainable procedures in compliance with regulations. This requires improvements in the spraying technologies since currently plant protection products are applied by means of hand-held equipment due to its lower cost and easy maintenance. In order to fulfil these requirements, a remote-controlled vehicle prototype (ROBOT SPRAY) was used. After optimizing the spray profile and the air assistance system of the “ROBOT SPRAY” sprayer in laboratory, its performance using two different nozzle sets (full cone and hollow cone) with and without air assistance was compared with those of a spray gun in a greenhouse tomato crop. The spray deposition on canopy, spray coverage and losses to soil were assessed. The “ROBOT SPRAY” provided better penetration and coverage on the underside of the leaves while no improvement was shown with the use of air assistance. Overall, a higher spray deposition was observed for the full cone nozzles when compared to hollow cone nozzles.
