Which statement is NOT a cultural control method for weeds?

• A. Chemical herbicides
• B. Mulching and sanitation
• C. Landscape fabrics
• D. Tilling as a tactic

Answer: (A)

Cultural weed control relies on changing the growing environment to suppress weeds rather than applying chemicals. Chemical herbicides do the opposite—they use chemical methods to kill or inhibit weeds, which makes them not part of cultural control. Mulching and sanitation reduce weed pressure by blocking light, conserving moisture, and removing weed sources. Landscape fabrics physically prevent weed germination by shading the soil. Tilling disturbs the soil and weed seedlings, disrupting their growth as a mechanical, non-chemical tactic. So the statement that is not a cultural control method is the use of chemical herbicides.
