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 ...
A new pest management research facility: Scion’s large-scale precision track sprayer
(New Zealand Plant Protection Society (Inc), 2014)
A new large scale precision track sprayer has been developed and evaluated for spray deposition and pesticide application research under controlled conditions. The spray room is fitted with a 4 m wide electrically driven ...
Phase doppler flux comparisons
(American Society of Agricultural and Biological Engineers, 2016-07)
The movement of droplets in time and space (i.e. flux) is essential to know when measuring and/or predicted spray drift via agricultural application. A study was performed to assess the flux measurements of a phase Doppler ...
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 ...
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 ...
