What sign and posting duration are required when applying an herbicide-fertilizer mixture to turf?

• A. Landscape warning sign; until sunset of the following day
• B. ATCP 29 warning sign; for at least 24 hours
• C. Fertilizer warning sign; until sunset of the following day
• D. Landscape warning sign only; for at least 48 hours

Answer: (A)

When herbicides are mixed with fertilizer and applied to turf, the notice must come from a landscape warning sign that specifically marks landscape areas like lawns. This sign should stay up until sunset of the following day, providing a clear, visible warning for the immediate post-application period when exposure risks are highest. The ATCP 29 warning sign is a broader pesticide notice and isn’t the required choice for turf in this scenario, and a fertilizer warning sign alone wouldn’t communicate the pesticide hazard after treatment. So, landscape warning sign posted until sunset the next day best fits the safety and regulatory intent for turf treatments.
