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 ...
SPECTRUM AND VELOCITY OF DROPLETS OF SPRAY NOZZLES WITH AND WITHOUT AIR INDUCTION
(Soc Brasil Engenharia Agricola, 2018-03-01)
The aim of this study was to evaluate the spectrum and the velocity of droplets produced by nozzles with and without air induction, under different pressures and flow rates. The experiment was conducted in a completely ...
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 ...
SPECTRUM, VELOCITY AND DRIFT OF DROPLETS SPRAYED BY NOZZLES WITH AND WITHOUT AIR INDUCTION AND MINERAL OIL
(Soc Brasil Engenharia Agricola, 2017-05-01)
The aim of this study was to evaluate the spectrum, the velocity and the potential drift risk of droplets sprayed by nozzles with and without air induction, with the addition of mineral oil to the spray solution. The ...
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. ...
Spray nozzles and droplet size effects on soybean canopy deposits and stink bugs control in west region of Sao Paulo state-Brazil
(Springer, 2020-01-29)
Stink bugs are one of the most relevant pest affecting soybean yields beyond the physiological and sanitary quality of the soybean seeds. The aim of the present study was to evaluate the effect of spray nozzles and droplet ...
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 ...
Assessing a novel smartphone application - SnapCard, compared to five imaging systems to quantify droplet deposition on artificial collectors
(Elsevier B.V., 2016-10-01)
Previous work sought to compare the results from imaging software for characterising droplet coverage, but none exists examining these five software programs: Droplet Scan (R), Swath Kit (R), Deposit Scan, Image J, and ...
Qualidade da aplicação em trigo conforme reduções da taxa aplicada em associação com diferentes pontas de pulverização
