Which of the following label statements refers to a route of entry?

The correct statement that refers to a route of entry is that which specifies the limitation on application near drinking-water wells. This statement addresses a particular pathway through which pesticides can enter the environment and potentially contaminate water supplies. By indicating a safe distance to maintain from drinking-water wells, it highlights the importance of protecting water sources from pesticide contamination, which can result from runoff or leaching into the groundwater.

Choosing to apply the product more than 50 feet away from these wells is a precautionary measure to prevent any adverse health effects that could occur if contaminated water is consumed. It emphasizes the significance of understanding how and where pesticides can influence various environmental components, specifically water sources that are critical for human and ecological health.

Other statements, such as those regarding keeping products out of reach of children, ensuring ventilation during use, and storing in dry conditions, do highlight safety measures but focus more on preventing exposure to people rather than addressing environmental entry points for harmful substances.
