Which would be an appropriate way to describe a relatively low-toxicity pesticide product to the customer?

Describing a relatively low-toxicity pesticide product as "use with caution" communicates to the customer that, while the product is safer than high-toxicity alternatives, it still requires careful application and consideration. This phrase serves as an important reminder that even low-toxicity substances can pose risks under certain conditions or if misused.

It highlights the need for appropriate handling, storage, and application practices to ensure both personal safety and environmental protection. This term also encourages customers to read the product label for specific instructions, reinforcing the importance of following guidelines to minimize any potential risks.

The other phrases do not adequately convey the need for responsible use. For instance, suggesting "use liberally" might imply that there are no restrictions or concerns regarding the amount used, which could lead to over-application and negative consequences. Similarly, stating "use without restrictions" could mislead the customer into believing that there are no safety considerations, ignoring the need for caution even with lower-toxicity products. "Use with permission" also does not accurately reflect the nature of pesticide use and can create confusion about the level of oversight needed during application.
