Pesticide regulation centers on who may buy and apply the product based on potential risk. The two main classifications are restricted use pesticides, which require a certified applicator and strict use controls, and general use pesticides (also called unclassified use), which can be purchased and used by the general public as long as the label is followed. The other groupings—organic vs inorganic, natural vs synthetic, or over-the-counter vs prescription—describe product characteristics or consumer access, not the core regulatory distinction that determines eligibility to purchase or apply. So the best choice highlights the fundamental regulatory split between restricted use and general use pesticides.
