Which of the following is true regarding pesticide toxicity?

C is correct because it emphasizes the importance of safety and risk management when using pesticides. Selecting pesticides with lower toxicity levels helps reduce potential harm to humans, animals, and the environment. By prioritizing products that are less toxic, applicators can minimize the risks associated with pesticide use, leading to safer application practices while still achieving effective pest control.

Understanding pesticide toxicity is crucial for responsible pesticide use. While it’s essential to choose effective products, the level of toxicity should also be considered to ensure that the potential adverse effects on health and the ecosystem are minimized.

The other options don't align with the principles of safe pesticide application. For instance, the method of application can significantly influence toxicity levels and exposure risk. Additionally, higher toxicity doesn't inherently mean lower efficacy, as some highly toxic substances can be very effective against pests. Lastly, while labeled products provide important safety information, the assertion that only labeled products can be harmful is misleading; misuse or accidental exposure to any pesticide can result in harm, regardless of its labeling status.
