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. ...
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 ...
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 ...
Cold gas spray coatings: Basic principles, corrosion protection and applications
(2017-01-01)
In this review, the beginnings and evolution of the cold gas spray (CGS) technique are described, followed by the main fundamental aspects of the technique together with a description of the several spraying systems up to ...
Air-assistance in spray booms which have different spray volumes and nozzle types for chemically controlling spodoptera frugiperda on corn
(2012-04-01)
The study aimed to evaluate the performance of air assistance in spray booms using different types of nozzles and spray volumes. We took into account spray deposits, fall armyworm control and crop corn performance in a ...

Localized application of insecticide combined with fertilizer on corn controls Spodoptera frugiperda (smith) and reduces spray drift
(2014-01-01)
Pesticides are important tools in agriculture for several decades, providing control of pest and diseases for an increasing demand of food by the growth of population. However, pesticides are often associated with ...
INFLUENCE OF NOZZLE TYPE AND SPRAY RATES ON CORN AND WEED PLANTS DROP DEPOSITIONS
(Univ Federal Uberlandia, 2014-11-01)
The objective of this study was to evaluate different nozzles and spray rates on drop deposition in corn (Zea mays), Euphorbia heterophylla and Brachiaria plantaginea, both weeds located at and between crop rows. The ...
INSECTICIDE SPRAYING IN SOYBEAN PLANTS: DIFFERENT NOZZLES MODELS AND AGROMETEOROLOGICAL CONDITIONS
(Soc Brasil Engenharia Agricola, 2018-09-01)
The aim of the experiment was to evaluate the quality of the spraying by the spray volume deposit provided by different nozzles models in two agrometeorological conditions of application. Four parameters related to spray ...
