Agrochemical spray drift; assessment and mitigation—A review*

Journal of Environmental Science and Health - Part B Pesticides, Food Contaminants, and Agricultural Wastes, 2010
During application of agrochemicals spray droplets can drift beyond the intended target to non-target receptors, including water, plants and animals. Factors affecting this spray drift include mode of application, droplet size, which can be modified by the nozzle types, formulation adjuvants, wind direction, wind speed, air stability, relative humidity,

Drift of 10 herbicides after tractor spray application. 2. Primary drift (droplet drift)

Chemosphere, 2006
In the present study the primary drift of 10 herbicides was investigated in five field experiments, and the amount deposited per surface area was quantified outside the application area using simple passive dosimeters. In addition, samples for measuring a possible background value were taken upwind of the sprayed field.

Spray drift as influenced by meteorological and technical factors

Pest Management Science, 2011
AbstractBACKGROUND: The objective of this study was to investigate spray drift from a conventional field sprayer as influenced by meteorological and technical factors, and to provide spray operators with data on which to base sound judgements when applying pesticides.

Shields to Reduce Spray Drift

Journal of Agricultural Engineering Research, 1997
Abstract The effects of several spray-boom shield designs and ‘‘low-drift ’’ nozzles on spray drift are presented. Results are based on experiments conducted in a wind tunnel. Performances of all experimental shields were evaluated under two spray pressures (0·15 and 0·3 MPa), and two air velocities (2·75 and 4·80 m/s) in the wind tunnel.

REAL TIME SPRAY DRIFT PREDICTION

Acta Horticulturae, 2001
The production of plant based food products inevitably involves pest and disease management. The usual method is spray application of fungicides and insecticides, but increasingly the risks from off site movement of pesticides as spray drift are becoming unacceptable. Considerable effort has gone into modelling the spray drift process.

Spray Drift Mitigation with Spray Mix Adjuvants

Applied Engineering in Agriculture, 2008
Numerous drift reduction adjuvants and spray deposition aids are available to applicators of crop production and protection chemicals. Performance of many of the newly introduced drift control adjuvants has not been well documented for aerial application.

The measurement of spray drift

Pesticide Outlook, 2003
Paul Miller from Silsoe Research Institute reviews the methods by which droplet drift can be measured, the factors that influence the levels of drift and the ways that data relating to the risk of drift can be used when selecting application systems.

EVALUATION OF SAMPLERS FOR SPRAY DRIFT

Transactions of the ASAE, 1998
Collection of airborne spray drift of malathion released from a ground-driven boom sprayer was investigated using six types of samplers: (1) horizontal alpha cellulose fallout sheets; (2) high-volume air samplers; (3) sampling trains of rotary disk impactor and two bubblers (RDI); (4) rotating rod samplers; (5) vertical string samplers; and (6 ...

Effects of glyphosate spray-drift on plant flowering

Environmental Pollution, 2021
Recent studies have shown that sub-lethal doses of herbicides may affect plant flowering, however, no study has established a direct relationship between the concentrations of deposited herbicide and plant flowering. Here the aim was to investigate the relationship between herbicide spray drift deposited on non-target plants and plant flowering in a ...

An Interactive Spray Drift Simulator

2010 Pittsburgh, Pennsylvania, June 20 - June 23, 2010, 2010
The off target movement of pesticides, known as spray drift, results in a reduction in application rates, damage to non-target organisms, and environmental concerns. Much of this drift can be eliminated if its prevalence is understood and best management practices are implemented.
