WEATHER CONDITIONS OF PONTAL OF PARANAPANEMA AND AERIAL SPRAYING OF PESTICIDES
(Univ Estadual Paulista Julio Mesquita Filho, 2020-05-01)
Aerial spraying of pesticides has increasingly become a topic for discussion about its viability and safety. If, on one hand, it is a tool for monetary gains and time reduction in agricultural sectors, conversely, exposes ...
Características da pulverização produzida por pontas Yamaho da série 'D'
(2002-09-01)
This study evaluated the characteristics of spray produced by Yamaho nozzle tip'D'series. The droplet size of nozzle tips D3, D4, D5, D6 and D8 were evaluated at 703, 1.050, 1.406, 1.758, 2.110, 2.461 e 2.813 kPa pressures ...
Spray volume deposits and fungicide efficacy on soybean rust (Phakopsora pachyrhizi)
(2019-10-01)
Soybean rust (SBR), caused by Phakopsora pachyrhizi, is one of the most destructive fungal diseases affecting soybean yields in many countries. Fungicide application methods that provide better SBR control efficacy may ...
Computational simulation of wireless sensor networks for pesticide drift control
(SpringerNetherlands, 2014-06)
The efficient application of low cost pesticides is a challenge for agricultural production. Pesticide drift is a major cause of environmental contamination. At the time of application, it is essential to know the environmental ...
Effects of application rate on spray deposition, stink bug control, and yield in soybean crops
(2022-02-01)
Stink bugs are economically important pests in soybean crops, affecting yield as well as the physiological and sanitary quality of grains or seeds. The present study aimed to assess the spray deposition into soybean canopy, ...
Knowledge on adjuvant properties, disposal of pesticideresidues and spray drift occurrence in the state of mato grosso
(2016-03-01)
This paper aimed at investigating the knowledge level of people working on pesticide spraying activities concerning spray adjuvant properties, as well as collecting information on disposal locations for residues from ...
Influência dos volumes de pulverização, tipos de ponta e adjuvantes sobre o controle da phoma de café
(2017-01-01)
Pesticides are often applied under incorrect conditions such as inappropriate nozzles types and high spray volumes. Such errors result in spray drift and run off, causing inefficiency on the control of pests and diseases, ...
Optimization of spray deposition and Tetranychus urticae control with air assisted and electrostatic sprayer
(Univ Sao Paolo, 2017-01-01)
Improved spray deposition can be attained by electrostatically charging spray droplets, which increases the attraction of droplets to plants and decreases operator exposure to pesticide and losses to the environment. ...
Dispersion and evaporation of droplets amended with adjuvants on soybeans
(2013-02-01)
Quantification of the effects of adjuvants on droplet behaviour on plant surfaces is needed to improve pesticide spray application efficiency for soybeans. Dispersion and evaporation of single 300-μm diameter droplets ...
Assessing the deposition and canopy penetration of nozzles with different spray qualities in an oat (Avena sativa L.) canopy
(Elsevier B.V., 2016-03-01)
Consistent spray coverage that is evenly distributed throughout the canopy is necessary to control pest populations that can negatively affect yield. As applicators are switching to Coarser spray quality nozzles to reduce ...
