What does WARNING on a pesticide label typically mean?

The presence of the word "WARNING" on a pesticide label indicates that the product is moderately likely to cause acute illness if handled or applied improperly. This label is used to inform users that while the pesticide is not considered the most toxic category, it does still pose significant health risks, particularly to humans through exposure. Understanding this hazard level is vital for safe handling and application, as it encourages users to implement appropriate safety precautions when using the product.

Moreover, the other options do not accurately reflect the meaning of the "WARNING" designation. For instance, it does not imply that the product is non-toxic to humans, safe for pets, or necessarily approved for food crops—all of which require separate evaluations and labeling indications based on specific tests and regulations.
