​Reynolds reviews and presents research findings about the four main sources of off-target movement: particle drift (near drift), volatility (far drift), contaminated equipment (especially sprayer hygiene), and misapplication. In discussing equipment, Reynolds outlines the use of deactivators and the effects on growth and yield of soybean and cotton. Other topics include how concentrations are reported, what products are approved, and how air samplers are used.
