Adjusting irrigation schedules to manage disease is an example of cultural control.

• A. True
• B. False
• C. Not sure
• D. Sometimes

Answer: (A)

Cultural controls involve changing the growing environment to reduce disease pressure. Adjusting irrigation schedules is a classic example because the amount and duration of leaf moisture strongly influence many plant diseases. By watering in a way that minimizes foliar wetness—using methods like drip irrigation, watering at the soil level, and scheduling irrigation for early in the day so leaves can dry before night—you reduce the window when pathogens can infect. Improving drainage, avoiding overwatering, and promoting better air movement around plants further lowers disease risk. These practices manage disease without chemicals, so this is a cultural control.
