Determining drift in spray tips evaluated under different wind speeds [PDF]

Revista Ciência Agronômica
The application of pesticides is essential in modern agricultural production. The concept of drift refers to the undue displacement of a product, which moves to areas outside the intended target, usually due to air currents.

SPECTRUM, VELOCITY AND DRIFT OF DROPLETS SPRAYED BY NOZZLES WITH AND WITHOUT AIR INDUCTION AND MINERAL OIL [PDF]

Engenharia Agrícola, 2017
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.

Assessment of Spray Drift with Various Adjuvants in a Wind Tunnel

Agronomy, 2022
When pesticides are sprayed, a significant portion of the droplets drifts away from the target. Using an adjuvant in spray liquid is an easy option for reducing droplet drift because there is no need to make any changes to the sprayer.

Study of a test methodology to assess potential drift generated by air-assisted sprayers

Journal of Agricultural Engineering, 2013
During pesticide application spray drift may cause diffuse pollution phenomena in the environment. In the last years the European Union, through the Directive on the sustainable use of pesticides (128/2009 EC), has recommended the adoption of measures ...

Thermodynamic Pathways of Nonequilibrium Solidification in Wire‐Arc Additive Manufacturing Fe‐Based Multicomponent Alloy Structures

Advanced Engineering Materials, EarlyView.
Geometry‐driven thermal behavior in wire‐arc additive manufacturing (WAAM) influences microstructural evolution during nonequilibrium solidification of a chemically complex Fe–Cr–Nb–W–Mo–C nanocomposite system. By comparing different deposits configurations, distinct entropy–cooling rate correlations, segregation, and carbide evolution are revealed ...

Drift from orchard spraying

Proceedings of the New Zealand Plant Protection Conference, 1997
Research from 1989 to 1996 into drift from air blast orchard spraying, principally in kiwifruit blocks with live shelter, is reviewed. A mass balance study showed 96% of applied vinclozolin could be accounted for with 75% on the target crop, 19% on the ground or shelter and about 2% leaving the block as drift.

Polymeric Drift Control Adjuvants for Agricultural Spraying [PDF]

Macromolecular Chemistry and Physics, 2016
The movement of a pesticide or herbicide to an off‐target site during agricultural spraying can cause injury to wildlife, plants and contamination of surface water. This phenomenon is known as spray drift and can be controlled by spraying during favorable environmental conditions, and by using low drift nozzles and drift control adjuvants (DCAs ...

Air‐Pressure–Actuated Vibroacoustic Metamaterial With Tunable Bandgap: Design, Modeling, and Characterization

Advanced Engineering Materials, EarlyView.
This article presents the design, modeling, and characterization of air‐pressure–actuated programmable vibroacoustic metamaterials (PVAMM). The study focuses on leveraging air pressure to dynamically tune resonance frequencies for effective noise attenuation.
