Driftmetingen Munckhof MAS boomgaardspuit 2020-2021

Research output: Book/ReportReportProfessional


Results of spray drift experiments are presented of the Munckhof MAS cross-flow fan orchard sprayer in comparison with a reference spray technique for fruit crop spraying in The Netherlands. The Munckhof MAS sprayer was equipped with controllable air valves and drift reducing nozzles (Lechler ID 90-01 C at 5 bar spray pressure, 90 % drift reduction), the PTO of the tractor, controlling the fan speed, was limited to 300 rpm. The Munckhof MAS orchard sprayer used a specific protocol for the outer three tree rows, limiting the amount of air support out of the orchard and spraying the outer tree row from one side. During the spray drift experiments, performed in 2020 and 2021, the downwind outer 24 m of an apple orchard was sprayed at the full leaf stage (BBCH 75-91) using the fluorescent tracer Acid Yellow 250. Spray drift deposition was collected downwind on a mowed grass area up to 25 m distance from the last tree row. For the Munckhof MAS orchard sprayer spray drift reduction at 4.5-5.5 m distance from the last tree row was 98.9% in comparison with the reference spray application.
