Which of the following is prohibited under Section 2(ee) of FIFRA?

The selection of the option regarding the prohibition of using a pesticide on non-target pests under Section 2(ee) of FIFRA is accurate because this section specifically defines improper pesticide use as any application that contradicts the labeling instructions. Pesticide labels are legally binding documents that dictate how and where a pesticide can be applied to ensure effectiveness and environmental safety.

Using a pesticide on non-target pests can lead to various issues, including harm to beneficial organisms, unintended exposure to humans and animals, and potential contamination of the environment. This kind of misuse can violate the label's intent and regulations established by FIFRA, which aims to protect human health and the environment from the potential hazards of pesticide use.

In contrast, applying a pesticide as recommended on the label, mixing approved pesticides with a fertilizer if permitted, and applying a pesticide within label restrictions all align with legal compliance under FIFRA. Each of these practices adheres to the guidelines set forth in pesticide labeling, which is critical for responsible and safe pesticide application.
