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 ...
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, ...
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 ...
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 ...
Performance of new flat fan nozzle design in spray deposition, penetration and control of soybean rust
(Springer, 2019-11-01)
Fungicide application technology to control soybean rust (SBR) is lacking and requires optimization to improve spray coverage in the lower part of the crop canopy as well as the spray distribution uniformity. The goal of ...
Fungicide spray coverage and deposition in soybean asian rust managementCobertura e depósito de calda fungicida no manejo da ferrugem asiática em soja
(2019-09-01)
At maximum vegetative growth, sprays with fungicide to control Asian rust (Phakopsora pachyrhizi Sydow and P. Sydow) should reach high canopy penetration and plant coverage. Therefore, the central objective of this study ...
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 ...
Determining the drift potential of Venturi nozzles compared with standard nozzles across three insecticide spray solutions in a wind tunnel
(Wiley-Blackwell, 2016-08-01)
BACKGROUNDPrevious research has sought to adopt the use of drift-reducing technologies (DRTs) for use in field trials to control diamondback moth (DBM) Plutella xylostella (L.) (Lepidoptera: Plutellidae) in canola (Brassica ...
Qualidade da aplicação em trigo conforme reduções da taxa aplicada em associação com diferentes pontas de pulverização
(Universidade Federal de Santa MariaBREngenharia AgrícolaUFSMPrograma de Pós-Graduação em Engenharia Agrícola, 2013-11-30)
Nowadays there is a trend of become the operational of agrochemicals spray faster. Then, it may cause a direct impact on the spray quality of a given product, influencing even directly the effectiveness of it control. The ...
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 ...
