Which signal word is associated with a diamond shape on pesticide labels?

The signal word associated with a diamond shape on pesticide labels is "Warning." This designation typically indicates that the pesticide is moderately toxic and poses a risk, but not as severe as those labeled with "Danger." The diamond shape serves as a visual cue, allowing users to quickly identify the level of hazard associated with the product. In the context of pesticide labeling, the use of "Warning" alerts users to take appropriate precautions without implying the highest level of risk, thus distinguishing it from other signal words that may imply greater danger or toxicity. Recognizing these visual signals is essential for safe handling and application of pesticides, which ensures the safety of users and the environment alike.
