The H2020-project OPTIMA concept of smart sprayer relies on several functionalities, including variable nozzle spacing for bed-grown carrots, based an air-assisted boom sprayer. A prototype was designed and evaluated though canopy deposition, ground losses, spray drift potential. Four bed configurations, various types, angles, sizes (XR8004, combination AIUB8504/AI11004, AI8004, XR8002) at the ...

The systematic use of plant protection products is now being called into question with the growing awareness risks they can represent for environment and human health. application precision agriculture technologies helps to improve agricultural production but also rationalize input costs ecological footprints. Here we present a study on fungicide efficiency its impact grass quality golf course ...

In a mature Vitis labrusca L. ‘‘Niagara’’ vineyard, we compared an airblast sprayer and an air-assisted rotary atomizer (AARA) low-volume sprayer for coverage of grape clusters and control of grape berry moth, Paralobesia viteana. In addition, the effect of spray volume on control of fungal diseases was evaluated using the fungicides ziram and azoxystrobin applied with an airblast sprayer. For ...

Highlights Three automatic boom height systems were compared: BoomTrac Pro (A), AutoBoom XRT (B), and UC5 Passive Roll (C). Boom leveling performance was quantified for three runs on each of terrains at least speeds. System B kept the significantly closer to target than Systems A C. had less variability Abstract . Automatic reduce agricultural sprayer height. Consistent is important key reasons...
