Comparison of spray dose measured on leaf surfaces with spray coverage estimated from Kromekote® paper
(New Zealand Plant Protection Society Inc, 2015)
The control of tomato potato psyllid largely depends on effective application of pesticides. This paper presents an experiment to measure deposition using leaf washing of spray containing water and rhodamine dye on a potato ...
Drift reducing potential of low drift nozzles with the use of spray-hoods
(The New Zealand Plant Protection Society Inc., 2014)
A field study was conducted in November 2013 to assess the drift reduction potential of a three headed spray-hood unit with either DG95-02 or DG95-015 low-drift nozzles used with the hoods either on or off (DG nozzles ...
Discharge coefficients of flat-fan nozzles
(American Society of Agricultural and Biological Engineers, 2017)
The discharge coefficient (Cd) is a measure of how much of the pressure energy of a nozzle is converted into kinetic energy. With the discharge coefficient known, the exit velocity of the liquid sheet from the nozzle can ...
Wind tunnel flux comparisons using a phase Doppler interferometer
(De Gruyter Open on behalf of the Polish Academy of Sciences, Institute of Plant Protection - National Research Institute and the Polish Society of Plant Protection, Committee of Plant Protection, 2017-09)
It is essential to know the movement of droplets in time and space (i.e. flux) when measuring and/or predicting spray drift in agricultural application. A study was performed to assess the flux measurements of a phase ...
