The possibilities of droplet spectrum regulation at application of plant protection products

Verification of the possibilities of a droplet spectrum regulation due to the change of working pressure, as well as the change of the size of the discharge orifice of a nozzle, was undertaken in laboratory conditions by measurement of the size of a droplet spectrum of the applied liquid. Selected types of low drift nozzles - Albuz AVI 025, Lechler ID 120, Lechler IDK 120-05, Lechler IDN 120-025, TurboDrop 03, Hardi INJET 02, Hardi B JET 02, Hardi LD 02and a flat fan nozzle Hardi ISO F 02-110 - underwent the measurement. The measurement of droplet spectrum was carried out at the nozzle's working height of 500 mm, and at working pressures of 0.1, 0.2, 0.3, 0.5 and 0.7 MPa. A laser measure equipment was used to measure the droplet spectrum of liquid.

Keywords: low-drift nozzle; droplet spectrum; working pressure
