How should a relatively low-toxicity pesticide be described to a customer?

Describing a relatively low-toxicity pesticide to a customer as "use with caution" is appropriate because it conveys a balanced message about the product's safety profile. This terminology suggests that while the pesticide has a lower risk compared to more toxic products, it still requires careful handling and attention to instructions to minimize any potential risks to human health, animals, or the environment.

Using this phrase also encourages customers to consider factors such as application methods, dosages, and environmental conditions while applying the pesticide. It fosters an understanding that even lower-toxicity pesticides are not completely without risks and should be used responsibly.

Other descriptions like "use with extreme caution" could unnecessarily elevate the perceptions of risk and may cause customers to avoid using the product when it might be suitable for their needs. The phrasing "use as directed," while technically correct, is more ambiguous and does not emphasize the need for caution regarding safety practices. Finally, suggesting to "use only in emergencies" might limit the effective use of the product when it could be safely utilized in regular pest management without waiting for a critical situation to occur.
