Do combinations of insecticides and acaricides influence spray droplet formation and the interaction with citrus leaves?
(2019-01-01)
In agriculture, the mixing of pesticides in tanks is a common practice. However, it is necessary to previse possible physical-chemical implications of this practice, which may affect the efficiency of the treatments ...
Effect of angled spray nozzle designs on spray distribution and droplet spectrum1Efeito de pontas de pulverização de jato angulado sobre a distribuição e espectro de gotas
(2021-01-01)
New technologies have been developed to promote uniform, sustainable, safe and effective application of phytosanitary products. In this scenario, spray nozzles of different designs and jet angles can optimize application. ...
INFLUENCE OF DROPLET SIZE ON SPRAY DEPOSITION AND WEED CONTROL USING GLYPHOSATE
(2021-07-01)
Droplet size is one of the most important factors that affect spray deposition and weed control through the use of herbicides. The aim of this study was to evaluate the influence of the droplet size on the spray deposition ...
Droplets pinned at chemically inhomogenous substrates: A simulation study of the two-dimensional Ising case
(American Physical Society, 2016-05)
As a simplified model of a liquid nanostripe adsorbed on a chemically structured substrate surface, a two-dimensional Ising system with two boundaries at which surface fields act is studied. At the upper boundary, the ...

PERFORMANCE OF AIR INDUCTION SPRAY NOZZLE MODELS UNDER DIFFERENT OPERATING CONDITIONS
(Soc Brasil Engenharia Agricola, 2020-11-01)
For the successful application of phytosanitary products, it is essential to understand the spraying process well. The present work aims to evaluate the spectrum and speed of the droplets produced by different spray nozzle ...
INFLUENCE OF GLYPHOSATE CONCENTRATIONS ON SPRAY SOLUTION PHYSICOCHEMICAL CHARACTERISTICS AND DRIFT POTENTIAL
(Soc Brasil Engenharia Agricola, 2020-01-01)
The herbicide glyphosate is sprayed with varying application volumes that result in different concentrations used in the spray solutions. Thus, this study aimed to evaluate the effect of glyphosate concentrations on the ...
