Knowra Pesticide drift Pesticide drift Pesticide drift is the movement of pesticides beyond the area where they were applied. It can occur during application or later through evaporation and transport.
Spray drift : The airborne movement of pesticide droplets or particles away from their intended target during application. It is the main form of drift while pesticides are being sprayed.
Pesticide application : The deliberate delivery of pesticides to crops, structures, land, or other targets. Drift begins with an application whose material can move beyond its target.
Pesticide exposure : Contact between a person or organism and a pesticide through inhalation, ingestion, or skin contact. Drift is one pathway by which unintended organisms can encounter pesticides.
Pesticide runoff : The movement of pesticides across land in flowing water after application. Unlike drift through air, runoff transports pesticides over land with water.
Vapor drift : The movement of pesticide vapors from a treated surface after application. Volatilized pesticides can drift after spraying has ended.
Pesticide nozzle : A device that shapes and regulates liquid flow from a pesticide sprayer. Nozzle design affects droplet size and therefore spray drift potential.
Pesticide residue : A pesticide or its breakdown products remaining on or in a surface, organism, or material. Drift can deposit residues on crops, homes, water, and other untreated surfaces.
Pesticide leaching : The downward movement of pesticides through soil, often toward groundwater. Leaching moves pesticides through soil rather than through the atmosphere.
Droplet size : The diameter of liquid droplets, which affects their suspension, evaporation, and deposition. Smaller spray droplets remain airborne longer and can travel farther.
Buffer zone : An area separating a pesticide-treated site from places or resources needing protection. Untreated buffers can reduce deposition on nearby sensitive areas.
