Laws, Regulations, and Environmental Protection
The regulatory framework
Applicators must understand that pesticides are regulated at federal and state levels. Under FIFRA (Federal Insecticide, Fungicide, and Rodenticide Act), EPA registers pesticides, and it is illegal to use a pesticide in a manner inconsistent with its labeling. States may impose stricter requirements. Know the concept of restricted-use pesticides (RUPs), which require certification, and that certification is how you legally apply them. Recordkeeping, reporting, and container disposal rules matter.
Environmental protection
Understand how pesticides move off-target: drift (wind, nozzles, pressure, droplet size), runoff (water over the surface), leaching (movement through soil to groundwater), and volatilization. Protect sensitive areas: wetlands, streams, wells, and habitats. Know pollinator protection (avoid applying during bloom, follow label bee warnings) and endangered species considerations. A common trap is confusing runoff (surface flow) with leaching (downward through soil), or assuming buffer zones are optional.
Traps
Questions test that "the label is the law," that applying at a higher rate than labeled is illegal even if it seems more effective, and that disposing of rinse water improperly is a violation. Also distinguish point-source from nonpoint-source pollution.
Rule of thumb
If the label does not allow it, do not do it. Reduce drift with lower pressure, larger droplets, and appropriate nozzles; respect buffers and weather.
