As pesticides become more biologically active and their use becomes more widespread the impacts of spray drift become a topic of considerable interest. The drifting of sprays is a complex process; factors influencing it include meteorological conditions, application parameters, and the nature of the target. Advances in aerial application technology and in our ability to measure drift, coupled with the adoption of new technologies for regulating pesticide application spurs a desire for a greater understanding of the pesticide application process. Experiments were conducted to quantify and profile drift from aerial applications of pesticide. The effects of atomizer type, spray quality and ground cover were examined. The materials and methods essential to conduct such a project were reviewed in detail.
