Which signal word is used for pesticides that are moderately or slightly toxic?

The signal word "Warning" is specifically designated for pesticides that are considered moderately or slightly toxic. This classification helps users and handlers of such products understand the level of risk associated with their use.

When pesticides are labeled with "Warning," it indicates that although they are not as harmful as those labeled with "Danger-Poison," they still require caution and appropriate safety measures during application and handling. This distinction is essential for ensuring safety in agricultural practices, as it informs users to take necessary precautions without inducing the same level of alarm that comes with more toxic substances.

In contrast, terms like "Danger-Poison" are used for highly toxic substances, while words like "Fatal" imply an immediate and significant threat to life, typically reserved for the most dangerous compounds. The term "Risk" does not serve as an official signal word within the pesticide labeling system and thus does not accurately convey toxicity levels as "Warning" does. Understanding these classifications allows users to make informed decisions while ensuring safety in pesticide application.
