Which of the following is NOT one of the three major pesticide toxicity warnings?

The correct answer is "Alert" because it is not one of the standard toxicity warning categories designated for pesticides. The three major toxicity warnings used are "Caution," "Warning," and "Danger," which indicate increasing levels of toxicity to humans and the environment.

• "Caution" is used for pesticides that are slightly toxic, requiring minimal precautions.

• "Warning" indicates moderate toxicity and necessitates more stringent safety measures.

• "Danger" is reserved for highly toxic substances that pose significant risks and mandate severe precautions.

"Alert," however, does not appear in these widely recognized classifications, making it clear that it is not a standard toxicity warning for pesticides. This distinction is important for understanding how to handle and apply pesticides safely, ensuring the protection of users and the environment.
