Airborne spray drift measurement using passive collectors and lidar Systems

Minimization of the risk associated with spray applications requires a proper understanding of the spray drift phenomenon. This fact has led to the development of several techniques to measure the deposition on horizontal surfaces as well as the ...

Single nozzle spray drift measurements of drift reducing nozzles at two forward speeds

, 2016
In 2011‒2012 single nozzle field experiments were carried out to determine the effect of different flat fan spray nozzles of the spray drift reduction classes 50, 75, 90 and 95% on spray drift at two different forward speeds (7.2 km h-1 and 14.4 km h-1).

Effects of sprayer operating parameters on airborne drift from citrus air-carrier sprayers [PDF]

, 2013
Florida citrus is mostly sprayed with various types of air-carrier sprayers.  These sprayers differ substantially in design features and are normally operated at different volume rates and ground speeds, during day and night applications.

A meta analysis of spray drift sampling

, 2011
There are many methods available for sampling spray drift, and a great variety of estimates of spray drift have been published. Available data on spray drift were collected from different studies and the measurements of spray drift were analysed to ...

German Regulation – Drift Modelling

, 2004
The application of plant protection products is associated with the unavoidable occurrence of direct drift. The volume of transported and deposited drops is influenced by prevailing technical, technological, and meteorological conditions.

Indoor spray measurement of spray drift potential using a spray drift test bench : effect of drift-reducing nozzle types, spray boom height, nozzle spacing and forward speed

, 2014
In a series of indoor experiments spray drift potential was assessed when spraying over a spray drift testbench with two different driving speeds, 2m/s and 4m/s, two different spray boom heights, 30 cm and 50 cm, and two different nozzle spacing, 25 cm ...
