Which of the following is an example of a cultural control? (Second example)

• A. Plant spacing
• B. Adjusting the time of planting
• C. Creating unfavorable conditions for the pest
• D. Selecting the right variety

Answer: (D)

Cultural controls aim to reduce pest pressure by altering the crop or its environment, without using chemical treatments. Choosing a variety that has inherent resistance to pests is a clear example because it changes the crop itself to be less susceptible, providing ongoing protection across the season without requiring repeated actions. This makes it a preventive, crop-centered strategy that works with the plant’s natural defenses.

Other options are also cultural practices, but they rely on timing or environmental manipulation that may vary season to season. Plant spacing and adjusting planting time change how pests and diseases encounter the crop, and creating unfavorable conditions modifies the environment to hinder pests. While useful, these approaches are more situational, whereas selecting the right variety establishes durable, built-in protection.
