Abstract The coupling of the valley drift (VALDRIFT) atmospheric dispersion/deposition model with the agricultural dispersal (AGDISP) aircraft wake model generates a modeling system for predicting the off-target drift of pesticides sprayed in a mountain valley.

Biosystems Engineering, 2010
A computer model of spray drift was developed, from an earlier particle-tracking model ( Miller and Hadfield, 1989 ), which can be used to predict non-target exposures to pesticides. The extended model includes the effects of multiple nozzles on a boom and a forward speed so that it is better able to simulate application conditions appropriate to ...

Drift Spraying for Vegetation Baiting
Bulletin of Entomological Research, 1959The term drift spraying denotes a method of applying an insecticidal spray whereby it is released at a height above the ground and allowed to drift with the wind while it gradually sinks; if the source of emission is moved in a line across the direction of the wind, insecticide will be deposited at a distance downwind of that line.

Adjuvant Effects on Spray Characteristics and Drift Potential
2001This paper describes studies that were conducted to investigate the effects of different surfactant and emulsion adjuvant chemistries and formulations on spray characteristics and drift potential of a commercial herbicide. Previous research has shown that surfactant, emulsion, and polymer adjuvants can affect the formation of sprays and liquid ...

Spray Drift Exposure Assessment
1983The Pesticide Registration Guidelines and certain regulations governing the application of pesticides under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) have undergone changes in recent years. In the area of spray drift evaluation, the U.S.

Evaluation of Spray Drift from Backpack and UTV Spraying
Transactions of the ASABE, 2017The objective of these tests was to evaluate pesticide drift from ground applications using a standard manual pump backpack sprayer and a UTV-mounted boomless sprayer. Three deposition sampler types were deployed: Mylar cards, water-sensitive papers, and artificial foliage.

Spray drift: impact of requirements to protect the environment
Crop Protection, 2000Spray drift studies in the US have evaluated the effects of application, meteorological and tank mix variables on spray drift. The data have been incorporated into models to predict drift from aerial applications, and to evaluate worst-case drift from ground rig (boom) and orchard airblast applications.
