What are pesticide uses covered by a Section 18 referred to?

The correct answer describes "Emergency uses" of pesticides that are covered under a Section 18 exemption of the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA). This provision allows for the use of pesticides in specific situations where there is an urgent need to control a pest that poses a significant threat to public health or agricultural resources.

Section 18 is used to provide temporary allowances for the use of a pesticide that has not been approved for that specific application by the Environmental Protection Agency (EPA), granted that certain criteria and justifications are met. The primary goal is to address unforeseen pest emergencies that could lead to substantial economic loss or serious threats to health.

Other options do not fit this specific context. General use pesticides refer to those that are widely available and deemed safe for almost anyone to use, while experimental uses pertain to research and development phases of pesticide efficacy and safety. Restricted uses involve pesticides that require special handling and training due to their higher toxicity or environmental risk. Therefore, the focus under Section 18 aligns specifically with emergency situations, highlighting the urgency and necessity of using pesticide solutions in those instances.
