What color must the lawn marker sign be?

• A. White.
• B. Blue.
• C. Red.
• D. Green.

Answer: (A)

White lawn marker signs are required so that anyone entering or near a treated lawn can easily notice the pesticide application. The white background provides high contrast with typical dark lettering, making the information legible from a distance and against green grass. Standardizing the color helps people recognize the marker quickly and reduces confusion with other signs that use different colors for different messages. When posting, include clear details such as what product was used and the date of application, and place the sign at the boundary of the treated area to alert others to the treatment.
