Final answer:
Restricted use pesticides can only be distributed by licensed pesticide dealers, per regulations like FIFRA administered by the EPA.
Step-by-step explanation:
Restricted use pesticides can only be distributed by licensed pesticide dealers. This is mandated by regulatory bodies such as the Environmental Protection Agency (EPA) under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA). These regulations ensure that pesticides are handled safely and responsibly to minimize risks to the environment and public health.
Licenses are issued to entities that demonstrate the necessary knowledge and infrastructure to handle such substances safely. Custom applicators, private applicators, and fertilizer dealers are not authorized to distribute restricted use pesticides to final users unless they also have the appropriate pesticide dealer license.
