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.

Modelling spray drift from boom sprayers

Computers and Electronics in Agriculture, 1997
A random-walk model, IDEFICS, is described to compute downwind spray drift from conventional boom sprayers in chemical crop protection. Spray deposits are computed downwind from the sprayed crop field.

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.

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 ...

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.

Effect of Drift Retardant Chemicals on Spray Drift, Droplet Size and Spray Pattern

1993
Specific objectives of this study were to determine the effects of various drift retardant chemicals (Direct, Driftgard, Formula 358, Nalco-trol, and Target) on droplet size, spray pattern, and spray drift reduction. The results of this study indicated that, at recommended rates, Nalco-trol provided the largest increase in volume median diameters of ...

The Effect of Adjuvants in Reducing Potential Spray Drift

2023
Drift containment during plant protection products spray application is essential to achieve sustainable crop protection. Adjuvants are designed to perform specific functions during the mixing and application of pesticides, but they can also reduce evaporation, foaming, volatilization, and spray drift.
