1. FIFRA established registration for all pesticides, which is only done after a period of data collection to determine the effectiveness for its intended use, appropriate dosage, and hazards of the particular material. When registered, a label is created to instruct the final user the proper usage of the material. If instructions are ignored, users are liable for any negative consequences.
   Label directions are designed to maximize the effectiveness of the product, while protecting the applicator, consumers, and the environment. Critics of the process point out, on the one hand that the research to produce the label is entirely done by the manufacturer and not much checking is done on its accuracy. On the other hand some consider the process too strict. It costs millions of dollars and often several years to register a pesticide, which limits production only to large players. Likewise many smaller or specialty uses are never registered, because the companies don't consider the potential sales sufficient to justify the investment.
2. Only a few pesticides are available to the general public, and can be used by anyone who will follow directions. Most pesticides are considered too hazardous for general use, and are restricted to certified applicators. FIFRA established a system of examination and certification both at the private level and at the commercial level for applicators who wish to purchase and use restricted use pesticides. The distribution of restricted pesticides is also monitored.
3. The EPA has different review processes for three categories of pesticides: antimicrobials, biopesticides, and conventional pesticides. The three categories have a similar application process, but have different data requirements and review policies. Depending on the category of pesticide, the review process can take several years. After a pesticide is registered with the EPA, there may be state registration requirements to consider.
