Monodisperse atomizers for agricultural aviation applications [PDF]

Conceptual designs of two monodisperse spray nozzles are described and the rationale used in each design is discussed. The nozzles were designed to eliminate present problems in agricultural aviation applications, such as ineffective plant coverage ...

Comparison of 1D PDA sampling methods to obtain drop size and velocity distributions inside a spray cone of agricultural nozzles [PDF]

, 2009
In agriculture, spray drift research is carried out in field experiments and by computer simulation. Regarding the latter approach, accurate knowledge of the initial spray is required.

Potential risk of drift from inclined fan nozzles

Revista Brasileira de Engenharia Agrícola e Ambiental
Pest, disease and weed control in large-scale crops depend on the application of agrochemicals. These applications are subject to several factors that can lead to drift.

Evaluation of Orifice Shape Design on Flat Fan Atomization [PDF]

EPJ Web of Conferences
The atomizer is a crucial component in spray columns used in mass transfer applications. Proper function of the atomizer can enhance mass transfer and reduce sorbent evaporation and droplet drift (physical loss).

How Much Do Adjuvant and Nozzles Models Reduce the Spraying Drift? Drift in Agricultural Spraying

American Journal of Plant Sciences, 2017
The spraying of herbicides in crops has become the main form of weed control. Although it means unexpected effects on non-target plants resulted by spraying drift. Thus, improvements in application techniques, as the best selection of spray nozzles and adjuvant, are essential to avoid environmental contamination and economic losses. On this work, we

Effect of Airflow Settings of an Orchard Sprayer with Two Individually Controlled Fans on Spray Deposition in Apple Trees and Off-Target Drift

Agriculture
Air-assisted sprayers are widely used in orchards to ensure deep canopy penetration and effective pesticide coverage, yet excessive or misdirected airflow often causes spray drift and ground losses. This study evaluated spray deposition efficiency, drift,

The use of air induction nozzles for herbicide application to sugar beet. [PDF]

, 2002
End of Project ReportTrials were carried out over a three-year period in Oak Park to compare airinduction with conventional nozzles for weed control in sugar beet. Two makes of low-drift nozzle (Bubble Jet and DriftBETA) were compared with conventional
