Preliminary investigation of Phase Doppler derived flux measurements in a wind tunnel for the sampling of orchard spray drift
(Julius Kühn-Institut, 2015)
Air-assisted spray equipment used for horticultural cropping systems depend on high air velocities to project the spray as well as to open the canopy for greater droplet penetration and deposition. However, these sprayer-types ...
Evaluation of spray drift in potatoes using various spray delivery systems
(New Zealand Plant Protection Society, 2014)
Spray deposition has previously been studied within a potato canopy. In a follow-up study, spray drift was evaluated using three treatments from the previous research plus two treatments encompassing an additional grower ...
Evaluation of spray deposition in potatoes using various spray delivery systems
(New Zealand Plant Protection Society Inc., 2013-10-28)
The tomato-potato psyllid incurs high control costs through intensive spraying and other treatments. A field study was conducted in March 2012 in Pukekohe, New Zealand, to evaluate the pesticide deposition potential of ...
Developing a comprehensive Drift Reduction Technology risk assessment scheme
(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, 2014-01-01)
Drift Reduction Technologies (DRTs) are becoming increasingly important for improving spray applications in many countries including New Zealand (NZ). Although there is a growing database on the performance of DRTs, there ...
Drift measurements for two systems of hydrogen cyanamide spraying in kiwifruit
(New Zealand Plant Protection Society (Inc.), 2018-07-26)
Kiwifruit are sprayed in late winter with hydrogen cyanamide to enhance with bud burst. The trellis layout of kiwifruit vines in combination with the canopy dormancy at that time of year means that a higher portion of the ...
Phase Doppler quantification of agricultural spray compared with traditional sampling materials
(New Zealand Plant Protection Society (Inc.), 2017)
The quantification of spray mass has historically been accomplished by means of fluorescent dyes and various string and ground samplers to capture the dye-laden spray. However, these methods are typically not used in close ...
